The continuous advancement of urbanization brings more challenges and pressures to urban planning, construction, management and development. In this context, China further proposes to build a new type of smart city based on the previous theory and practice of smart city. In recent years, many Chinese cities have carried out smart city pilot projects, which have effectively improved the level of public services, enhanced management capabilities and promoted urban economic development.

On April 11, 2016, the National Development and Reform Commission, the communist party of China central network security and information commission jointly chaired a "new type of intelligent city inter-ministerial coordination working group meeting for the first time", the meeting pointed out that to promote the new wisdom city construction of the CPC Central Committee and the State Council China based information and practical new type of urbanization development, to improve service level of urban management, promote the scientific development and make big decisions, is the implementation of the new industrialization, informatization, urbanization and agricultural modernization, greening the synchronous development of positive practice, to the "big five" concept of development "as the guidance, New ideas, new ways and new means will be used to promote the new development of smart cities in China.

On October 9, 2016, xi jinping in the Political Bureau of the CPC Central Committee general secretary 36 times explicitly pointed out that, when collective learning to understand deeply the role of the Internet in the country management and social governance, to carry out electronic government affairs, the construction of new cities and other communities in wisdom, in the data set and sharing as the way, the construction of the integration of national major data centers, propulsion technology integration, business integration, data integration, implementation across hierarchy, cross-regional, across different systems, across departments, business management and service together.

In recent years, the development of China's new smart cities has shown a good development trend, with remarkable progress in policy environment, infrastructure and application system, and is developing in depth with the support of artificial intelligence.

01 Policy environment continues to lead the development of new smart cities 

China attaches great importance to informatization and smart city construction. A number of policies and measures have been introduced in areas such as "Internet + government services", information integration, and the new generation of artificial intelligence. Some local governments have seized the development opportunities and issued relevant policy documents to make overall plans for urban IT application and smart city development.

The national level

The 19th National Congress of the Communist Party of China set forth the vision of a digital China, a smart society, and a cyber power, and called for efforts to focus on people's education, social security, quality employment, targeted poverty alleviation, health management, and social governance, thus defining a new development path for the building of smart cities. Put forward to promote the Internet, data fusion, artificial intelligence and the depth of the real economy, the development of digital economy, sharing economy, cultivate new growth points, forming a new kinetic energy, strengthen water conservancy, railways, highways, water transport, aviation, pipeline, power grids, information, logistics infrastructure construction measures such as network, will provide new support for the development of city information.

The central committee of the communist party of China, the State Council has promulgated the new generation of artificial intelligence development plan "about further expand and upgrade information consumption continues to release potential domestic demand guidance," "about" Internet + advanced manufacturing industry "development of Internet industry guidance" "to promote the Internet protocol version 6 (IPv6) scale deployment plan of action" outline of national innovation driven development strategy "about promoting the healthy and orderly development of the mobile Internet opinions such as policy, clearly put forward to modernization drive information as the main line, push the big data, information sharing and wisdom to the development of the society.

Ministry level

In April 2017, the Ministry of Industry and Information Technology, PRC issued the Three-Year Action Plan for the Development of Cloud Computing (2017-2019), which put forward the guiding ideology, basic principles, development goals, key tasks and safeguard measures for the development of cloud computing in China. The Guidelines for the Construction of a Comprehensive Standardization System for the Mobile Internet have been released to build a standard system for the mobile Internet. It is pointed out in the Notice of National Development and Reform Commission on Printing and Ispressing the "13th Five-Year" National Government Affairs Informatization Project Construction Plan that an integrated public infrastructure platform of government affairs information should be formed to jointly build and share, and generally meet the needs of government affairs application.

The former Ministry of Land and Resources and the former National Administration of Surveying, Mapping and Geographic Information promulgated the Notice on Promoting the Construction of Territorial-Spatial Basic Information Platform, which clearly defined the objectives, tasks and overall requirements for the construction of Territorial-spatial basic information platform. Standardization Administration of the People's Republic of China issued the national standards "Smart City -- Technology Reference Model" and "New Smart City Evaluation Index".

Among them, Smart City -- Technology Reference Model points out the concept reference framework of smart city, stipulates the business framework of smart city supported by information and communication technology, knowledge management reference model and technology reference model, as well as the technical principles and requirements for the construction of smart city. The new wisdom city evaluation indicators including huimin service, precise management, ecological livable, intelligent facilities, information resources, network security, reform and innovation, and citizens to experience 8 level evaluation index (figure 1), is the main basis of evaluation to carry out the new wisdom city, is to guide the healthy development of China's cities around new wisdom.

Office of the National Development and Reform Commission issued "about to organize the implementation of a new generation of 2018 notice information infrastructure construction project, points out that accelerating the" broadband China "strategy implementation, the demands in municipalities directly under the central government, provincial capital cities and the pearl river delta, Yangtze river delta, beijing-tianjin-hebei region as the focus, to carry out the 5 g network construction scale and application demonstration project. The quantum secure communication network operation service system should be constructed to further promote its application in the field of information and communication as well as government affairs, finance, power and other industries, and provide better network support for the development of new smart cities.

The local level

Provincial-level governments in Beijing, Tianjin, Shanghai, Chongqing, Guangdong, Jiangsu, Zhejiang, Anhui, Shandong and Ningxia have vigorously promoted the construction of new smart cities. Specific work plans will be made for "Internet Plus" public resource transactions, integration and sharing of government information systems, smart supervision, smart fire control, smart approval, smart finance, and smart families. At the same time, guangzhou, shenzhen, nanjing, hangzhou, ningbo, fuzhou, hefei, yinchuan and other cities issued the implementation of the central government about cloud computing, big data, Internet of things, and informatization policies and regulations, tries to build up a new city of wisdom, wisdom hospitals, intelligent community, markets, transportation, intelligent network, wisdom, civil air defense, wisdom is widely used in the field of logistics, wisdom, urban management, etc.

02 Innovative infrastructure development supports the construction of new smart cities

As the core of a smart city, infrastructure is the lifeline supporting the healthy operation of a smart city and the cornerstone of its sustainable development. Its construction level directly determines the development prospect of a smart city. Relevant studies point out that a smart city is a collection of hardware infrastructure (or physical capital) and the use and quality of knowledge communication and social infrastructure. The use of new digital technologies to coordinate and integrate traditional infrastructure is an important way to promote the upgrading of smart city infrastructure.

(1) Intelligent transformation of traditional infrastructure, including the perception and intelligent construction of water, electricity, gas and heat pipe networks, as well as roads, Bridges, stations, airports and other facilities;

(2) Information network infrastructure, including broadband, Internet of Things, convergence of three networks, etc., which is the information transmission system of smart cities;

(3) Information sharing infrastructure, including space-time information cloud platform, information security service facilities, etc., which is the public data storage, information exchange and operation support platform for smart cities.

At present, China's new smart city infrastructure construction continues to deepen. Steady progress has been made in the Broadband China strategy, and 5G trials have been launched, further enhancing the capacity of urban information infrastructure. New achievements in communication satellite and navigation technology have enhanced the ability of urban information acquisition and its application in urban construction, environmental monitoring, emergency response and disaster reduction. The continuous construction and evolution of big data center and space-time information cloud platform have expanded the application of big data and cloud computing in smart government affairs, smart urban management, smart transportation, smart medical care, smart pension, smart environmental protection and other fields.

New development of the Internet and communication technology has improved the level of urban information infrastructure

Broadband network is a strategic public infrastructure for the development of new smart cities in China. The development of broadband network plays an important supporting role in promoting information consumption and driving the transformation of development mode. In recent years, the central government has proposed to transform the economic development mode, accelerate the construction of "broadband China" and the deep integration of information technology and industrialization, so as to fundamentally change the economic development mode. With the steady progress of the construction of "broadband China", the effect of broadband speed is obvious. China Mobile's broadband users are accessing the Internet at a significantly higher rate using 4G networks, and 5G development has made another breakthrough. For the first time in the world, 5G base-station to terminal connectivity based on the 3GPP R15 standard has been realized.

In January 2018, the China Internet Network Information Center (China Internet Network Information Center, CNNIC) issued 41 times, the China Internet Network development state statistic report, according to a report by December 2017, scale of Chinese Internet users reached 772 million, accounting for 25% of the total number of global Internet users, Internet penetration rate of 55.8%, more than the global average of 4.1% (51.7%), 9.1% above the Asian average level (46.7%), 753 million mobile Internet users, Accounting for 97.5% of the total Internet users. The Global City Informatization Development Report 2017 also shows that among the 20 largest cities in the world, Beijing and Shanghai rank the 14th and 15th in the global smart cities respectively.

Smart city is the product of the new information technology revolution and scientific and technological change. It can deal with urban problems in a more intelligent and convenient way, facilitate the life of urban residents, and enhance the competitiveness and innovation of cities. The development of Internet communication technology and promote wisdom city construction supplement each other, inseparable, through the communication technology development can realize adjustment of economic structure, the new thinking, new service mode in traditional industries, government service and social management, culture, entertainment and other fields is widely used, make the mobile Internet, benefiting the people and help to achieve information new wisdom urban construction.

For example, in the culture and entertainment industry, mobile live streaming is expected to see explosive growth. According to the "Deep Research Report on Business Model Innovation and Investment Opportunities of Online Live Broadcast Industry", the number of online live streaming users reached 398 million in 2017, with a growth rate of 28.4%. It is expected that the number of online live streaming users will reach 460 million in 2018 and 507 million in 2019.

New achievements in remote sensing satellite and navigation technology have broadened access to urban information

Remote sensing technology is a "six" wisdom city construction concept (that is, a system architecture, a piece of heaven and earth one grid network, a general functional platform, a collection of data, run a city center, a set of standards), "a piece of heaven and earth the integration of city information service grid network" one of the key technologies and its space covering large, fast and efficient, abundant information, etc, is the dynamic of urban spatial information acquisition and monitoring the indispensable important technical means. With the development of remote sensing technology, remote sensing data has obvious characteristics of big data, and remote sensing has entered the era of big data.

China's satellite remote sensing data acquisition technology is constantly mature and has made new progress. The China Meteorological Administration and national defense industry bureau jointly issued the China's new generation of geostationary orbit meteorological satellite cloud image, and the first to obtain the 4 data (figure 3), marked the geostationary orbit meteorological satellite upgrade is implemented, and the successful launch "of the three, 04 star", become an international one of the most advanced wide imaging remote sensing instrument. As a result, China has the largest number and most comprehensive types of in-orbit meteorological satellites in the world, providing comprehensive observation information in meteorological, oceanic, forestry, agriculture and other application fields.

China's independently developed SuperView-1 01/02 commercial remote sensing satellite has successfully received images from all over the world, marking the official operational capability of China's first independently developed 0.5m-class high-resolution commercial remote sensing satellite constellation.

The Beidou Navigation Satellite System (BDS) is a global navigation satellite system that is being implemented by China, developed independently and operated independently, making China another country with an independent satellite navigation system after the United States and Russia. The navigation system is stable in performance and easy to use, and has the functions of positioning, speed measurement, timing, and short message communication. It is an important infrastructure of smart city, and plays a vital supporting role in the development of industries such as earthquake relief, Marine fishery, transportation, logistics, and the Internet of Things in smart city.

At present, China's independently developed Beidou Global Navigation Satellite System has entered the third stage of rapid development. China national accreditation supervision and management committee and under the guidance of industrial information technology, electronic company car networking product certification union, launched China's rapid positioning beidou chip "level" m, navigation accuracy from the original 10 m to 1 ~ 2 m, ended China's high precision satellite navigation and positioning products "organic coreless" history, marked the beidou satellite navigation of China independently controllable entering level meters positioning era (figure 4).

In addition, China's satellite navigation and positioning benchmark service system has been completed and put into operation. The system is China's largest satellite navigation and positioning service system with the widest coverage. It can provide free and open real-time sub-meter level navigation and positioning services to the public, as well as centimeter and millimeter level positioning services to professional users. The system consists of 410 national-level satellite navigation and positioning reference stations and more than 2,300 reference stations from provincial surveying, mapping and geographic information departments. The high-speed data transmission network is used to connect the national and 30 provincial data centers, forming a nationwide satellite navigation and positioning service "one network".

The construction of big data centers is improving day by day to enhance the city's information processing capacity

With the improvement of the urban Internet of Things and the increase of network information, a large number of user-generated content, audio, text, video, pictures and other unstructured data have become the main body of big data. Single big data technology cannot meet the requirements of data storage and analysis, and it is urgent to build a big data platform to meet the new needs. Big data platforms can promote the sharing, opening and exchange of data, and help to streamline administration and delegate power, innovate the way of government governance, optimize market services and strengthen market regulation.

From the perspective of application field, big data platform is mainly used in e-commerce, public security, public transportation, telecommunications, simulation and other fields, which can be divided into power big data platform, public transportation big data evaluation platform, telecommunications big data platform, water utilities big data platform, etc.

From the perspective of system construction, it is usually divided into data acquisition layer, computing storage layer, capability service layer, application layer, platform management layer, etc. Through the analysis of the research work on big data at home and abroad, it can be found that the research on big data platform is still scattered at present, and many business information systems such as public security and e-government are still at the primary processing level, lacking comprehensive development and application.

At the practical level, with the continuous advancement of new urbanization and "Internet +", the development of new smart cities has entered a stage dominated by massive data. In order to deepen the integration of the Internet and social and economic fields and promote the development and application of big data, provinces and cities have carried out the construction of government big data platforms. In November 2017, the second "number of DAMS in China" and the China Internet conference "to support the games zhangjiakou division" summit held in zhangjiakou, meeting around beijing-tianjin-hebei the construction of big data in test area, the convergence and application of large data resources as the core, the butt joint of Internet, big data resources platform, and the industry to discuss and share with large data push Beijing ji transformation and upgrading of industrial structure mode and experience.

In December 2017, the world conference on intelligent manufacturing "manufacturing industry data + technology" theme on the BBS, jiangsu, zhejiang, Shanghai big data federation held a signing the memorandum of cooperation, jointly promote the jiangsu, zhejiang industry cloud, big data platform construction, speed up the corresponding data applications, push the big data the promotion and application of generic technology in manufacture industry, help to improve industry standards of data construction and large data resource circulation and complementary development, to achieve resource sharing and common development.

Construction of spatiotemporal information cloud platform to support urban management and service decision-making

With the development of smart city, the public service platform of geographic information at the stage of digital city shows some deficiencies, such as single data application content, single sharing method, scarce real-time data, heavy workload of operation and maintenance, etc., which directly leads to the construction demand of spatiotemporal information cloud platform.

Wisdom city spatial and temporal information cloud platform is through the ubiquitous network, new high-tech means such as sensing devices, intelligent computing, real-time collection city all kinds of information of time and space, and form more thoroughly, wider perception of interconnection, smarter decisions and more spiritual services and more safe and reliable geographic information service platform, the wisdom of urban geographical spatial information infrastructure important and basic content.

Smart city spatiotemporal information cloud platform has the advantages of better experience, stronger real-time performance, greater mobility, higher controllability and more autonomy. The construction of cloud platform can realize the extensive sharing and full application of geographic information resources in smart cities, and reduce the difficulty of various departments and industries to obtain information. From the perspective of technical architecture system, the new spatiotemporal information cloud Platform of smart city is based on cloud architecture and consists of Infrastructure as a Service (IaaS), Data-as-a-Service (DAAS), Platform-as-a-Service (PaaS), and Softhare-as-a-Service (SaaS) (Fig. 5).

The former National Administration of Surveying, Mapping and Geographic Information issued the Technical Outline for the Construction of Smart City's Spatio-temporal Big Data and Cloud Platform in 2017, requiring all regions to speed up the pilot construction of smart city's spatio-temporal information cloud platform, and guiding the construction of spatio-temporal big data and spatio-temporal information cloud platform. The technical outline provides basic guidance for the construction of spatiotemporal information cloud platform of each city, which can give full play to the basic and link role of spatiotemporal information and standardize and guide the development of spatial informatization of smart cities.

With the deepening of the planning and construction of new smart cities, China has set off a boom in the construction of new smart city space-time information cloud platform. Jining City, Ningbo City, Wuhan City, Xiongan New Area, Zhengzhou City, Yunnan Province and other places have successively launched the prelude to the construction of the space-time information cloud platform for smart cities.

In October 2017, the Xiongan New Area held the High-end Forum on Smart Spatio-temporal Big Data for the Construction of the Xiongan New Area, which proposed to build a "Smart Spatio-temporal Big Data and Cloud Platform", and carried out demonstration applications in spatial planning, ecological monitoring, smart communities, public services and other aspects. At the same time, the Xiongan New Area is required to carry out a demonstration of new basic surveying and mapping construction. New basic surveying and mapping products of the Xiongan New Area, which are physical, three-dimensional, spatio-temporal and integrated above ground and underground, will be innovated and established.

"Wisdom in early November 2017, wuhan spatio-temporal information cloud platforms" as China's first wisdom city spatial and temporal information cloud platform is built, the platform in time and space information as the carrier, integration of the urban population, a legal person, such as building foundation information 8500, 250 million, have accumulated 1803 thematic information, in urban planning, land and resources management, the innovation of social management, taxation, wisdom, online public service, wisdom, urban management, emergency command, and the public service more than 30 areas to carry out the application.

At the end of November 2017, "chongqing wisdom spatio-temporal information cloud platform national pilot" project through the acceptance, the platform with cloud computing, Internet of things, big data, intelligent computing, mobile Internet and other new technology as the backing, is an important infrastructure of time and space of chongqing city informatization construction and the city's social exchange the only authority of public information resources sharing platform.

03 The application system continues to expand to highlight the role of the new smart city

Supported by urban information infrastructure, the application system of new smart cities continues to expand, and the application of smart cities has covered smart government affairs, smart urban management, smart planning, smart business, smart transportation, smart medical care, smart elderly care, smart environmental protection and many other areas of urban planning, construction, management, operation and maintenance.

New breakthroughs were made in smart government administration to support the improvement of the government's ability to manage and provide services

The emergence and application of big data and intelligent devices, as well as the arrival of the tide of mobile Internet, make the current social governance model urgently need to carry out modernization reform, and promote the formation and development of the new e-government organization, namely the smart government. Intelligent government is not a new form of government affairs, but an advanced stage after the development of e-government to a certain extent. Its essence is to introduce the information efficient disposal mechanism into the government affairs process of public departments, and then realize the transparency, science and intelligence of government affairs.

Academic circles is generally accepted that wisdom e-government is relying on big data, cloud computing, such as information technology, optimize the governance concept, content, methods, means, in order to realize the running clean and efficient government, the public governance and intensive precise and convenient public services benefiting the people and the social benefit is remarkable outstanding a new government operation mode, the wisdom of e-government is put forward based on the city and wisdom social this big background and macro system, in the urban planning and construction of new wisdom, wisdom, the government is undoubtedly one of the key areas, wisdom is key factor to improve the quality of the wisdom urban construction.

As smart government is characterized by simplicity, transparency, autonomy, mobility, real-time, intelligence and seamless connection, the construction of smart government can make the road of urban wisdom more smooth. Its advantages are mainly manifested in three aspects.

(1) We can make full use of the advantages of network information, change the traditional mode of government affairs and the mode of government management, and make the government information resources gradually change from the original "scattered" management mode to the "centralized" management mode;

(2) It can provide a basis for coordinated actions among urban units and effective cooperation between government and the public;

(3) In the fields of public security, medical and health care, urban management, and people's livelihood services, a convenient, efficient, safe and reliable intelligent social management and public service system should be built based on innovation of management and service modes.

Relevant ministries and commissions of the state have promoted the sound development of smart government affairs at the level of institutional design and top-level planning. In 2017, the National Development and Reform Commission issued the "13th Five-Year Plan for National Government Informatization Project Construction", which is of great significance for promoting intensive innovation and efficient development of government information construction, and forming a government information system that meets the requirements of the modernization of national governance system and governance capacity.

At the same time, some cities are actively exploring the practice of smart government affairs and have made a series of progress. For example, Yinchuan promotes the in-depth integration of online and offline of the physical government affairs service hall and the online citizen hall, promotes the electronic and networking of the whole process of administrative examination and approval, and accelerates the speed of the "do not meet, do it immediately" examination and approval. A 24-hour self-service system for the convenience of the people has been put in place to provide all-weather, multi-field and automated government services to the public through multiple ports and channels.

Hefei held the "Internet + Government Affairs Service" promotion meeting. Relying on the construction of municipal big data platform, it vigorously promoted the integration and sharing of government affairs information system and resources to provide data and information for the "Internet + Government Affairs Service" platform. A platform for exchanging and sharing government information resources at the municipal level has been set up, with 50 units, 161 business systems and 1.55 billion pieces of information collected. The connection between the municipal platform and the provincial platform was completed, and the unified identity authentication and payment functions were called at the provincial level, so as to ensure the real-time issuance of government service matters between the provincial and municipal platforms and the real-time reporting of the whole-process municipal office information.

We will build an information platform for smart planning to promote coordinated urban development

Urban construction fast, at present, the wisdom in the "world map", "Internet + e-government service" and other measures to vigorously promote the government reform background, to carry out the "rules" information platform construction, not only can coordinate different spatial planning in the planning period, planning goal and are obvious differences in the function orientation, can also integrate the National Development and Reform Commission, the ministry of land and resources, housing and urban-rural development, ecological environment, the Ministry of Transport, ten departments such as the state forestry administration of professional planning and management data, implement the data in the same "rules" platform of information linkage Shared and updated in real time, We will ensure that each city and county has one blueprint for its own planning, solve problems such as existing plans that have their own systems, conflict in content, and lack of coherence, and further enhance the application of information in cities and the development of smart cities.

Therefore, under the perspective of wisdom city "more rules and information platform, the wisdom city related data, cloud services, Internet of things, such as information technology applied to gauge one more platform to promote spatial information data sharing, to strengthen the departments in the planning process, to eliminate barriers, an important means of strengthening the functions of the government.

In August 2014, the National Development and Reform Commission, the Ministry of Land and Resources, the Ministry of Housing and Urban-Rural Development, and the Ministry of Ecology and Environment promoted the pilot work of "multi-planning integration", and the information platform of "multi-planning integration" was successively put into construction and continuously developed and improved in all provinces and municipalities across the country. Hainan Province, Ningxia Hui Autonomous Region, Xiamen City, Guangzhou City, Nanjing City, Shenyang City, Changchun City, Wenling City, Jiaxing City, Dali City, Deqing County and other cities have built the "multi-planning integrated information platforms."

We will build a smart urban management big data platform to improve the quality of urban management

Urban management is the basic guarantee for healthy urban operation and sustainable economic and social development. The digitalization, refinement, intelligentization and socialization of urban management are the major requirements of China's new smart city development strategy.

With the continuous advancement of urbanization in China, urban management is faced with a series of challenges under the new situation. In order to solve the urban management dilemma, intelligent urban management has emerged at the historic moment. Originated in the digital urban management, urban management construction essence, wisdom is the sublimation of digital urban management and development, make full use of the Internet of things, cloud computing, mobile Internet, such as a new generation of information technology, strengthen the information automation, supervision and management of fine, business functions, co-ordinated, service means diversification and auxiliary decision-making intelligent, humane law enforcement measures, finally realizes the elements of urban management, urban management process, the wisdom of the urban management decision-making, etc.

Smart urban management is an important part of the construction of smart city. In the construction of smart city, further rational use of urban management information technology will constantly improve the detection indicators of urban economy and environment, and promote the auxiliary management of cities. Smart urban management is based on the overall architecture of the Internet of Things, which is divided into the perception layer, the transmission layer, the support layer and the application layer from bottom to top. At the same time, the security guarantee system and the standard and specification system are built as the support (Figure 6).

Through the construction of smart urban management big data platform, urban management resources can be integrated, urban management behaviors can be standardized, and urban management efficiency can be improved. With the help of urban management map, scientific deployment and intelligent command can be realized to meet the requirements of all-weather, seamless and fine management of the city. The "10,000-meter cell grid method" is adopted to manage urban components and events, discover and deal with various urban problems in time, and improve the efficiency of urban management. Smart city management has become an important part of the construction of smart city. In the construction of smart city, further rational use of urban management information technology will constantly improve the detection indicators of urban economy and environment, and promote the auxiliary management of cities.

At the end of 2012, the Ministry of Housing and Urban-Rural Development issued the Interim Management Measures for the National Smart City Pilot Program, which set new requirements and clarified new directions for promoting the construction of smart urban management. Many cities have been brave in innovation and practice and carried out the construction of intelligent urban management platform, which has achieved remarkable results and accumulated valuable experience for the development and promotion of intelligent urban management.

In January 2017, yuhua district of changsha city management platform officially running wisdom, realize the information acquisition intellectualization, realized the "chengguan", urban management, sanitation, garden and so on should be brought into the unified management, the system with the public security department, the "tianwang" to realize a butt joint and enable the unmanned aircraft, the key area to implement real-time monitoring and management of blind area.

In December 2017, the official opening wisdom in xiuzhou district of jiaxing city urban management system, through the video monitoring point, unmanned aerial vehicles, mobile terminals, mobile terminal equipment and monitoring platform, working system, examination and approval system, single function such as plate, forming a "eye patrol monitor, mouse, smart send single, personnel disposal" efficient urban management model.

We will develop a smart medical care and old-age care system, and improve the level of information benefit the people

(1) Significant achievements have been made in the construction of smart medical treatment in China.

At present, China's population is aging rapidly and the incidence of chronic diseases remains high. The overall medical and health services for the residents still need to be improved. "Internet + medical treatment" has become a new opportunity for the development of medical services. The proposal and practice of smart medical treatment conform to the demand of the new medical reform for the construction of medical informatization.

Smart medicine refers to the use of the Internet of Things technology to realize the interaction between patients and medical personnel, medical institutions, medical equipment, promote the innovation of medical information mode, and finally realize real-time, intelligent, automated, interconnected dynamic services. Smart medical treatment is an important application in the field of people's livelihood in the strategic planning of smart city, and it is also the industrial upgrading and economic growth point driven by people's livelihood economy. Its construction and application is the trend of The Times.

Smart medicine can benefit the public, hospitals and regulators. For the public, it can provide more convenient, preferential and comprehensive quality medical services. For medical institutions, medical resources can be allocated more reasonably and effectively, and safer medical services and more efficient management can be provided. For regulators, smart medicine means more scientific, timely decision-making and emergency response.

In the country's vigorously advocate and support, the Chinese wisdom medical construction rapid development, health information construction framework has already appeared, regional health information platform construction carried out smoothly, realize the medical information resources sharing between different regions, the main application in the medical services, public health, health care, drug supervision, comprehensive management, and other fields, the intelligent medical system constantly improve. Some cities have made beneficial explorations and attempts, and achieved phased results.

In September 2017, Hefei Binhu Smart Hospital was inaugurated, providing a useful exploration for deepening medical reform and building modern hospitals.

In October 2017, "Peking University medical health data sharing platform in Beijing started, not only with the help of a platform to display for each queue resources for standardization of information, the establishment of a multi-level three-dimensional cooperative strategies and Shared mechanism, and also integrated the quality and health care field data of multi-source gradually form data sharing mechanism, the security and win-win and establish deep cooperation with other data platform.

In December 2017, the national health care big data center officially launched in changzhou, changzhou has completed the "integration of cities and counties" of regional health information platform, formed a relatively complete the total population of residents, electronic medical records and electronic health records database, data storage totaled 480 TB, 300 TB has housed large data centers, municipal platform has collected more than 460 ten thousand residents population information, 3.65 million electronic health records and 68.56 million medical records.

(2) China's smart pension construction has developed rapidly.

With the rapid development of information technology, the intelligent pension comes into being under the background that the existing pension model is difficult to solve the aging problem. With the help of modern information technologies (such as the Internet, social network, Internet of Things, mobile computing, etc.), it provides services such as medical care, entertainment, learning and communication around the life of the elderly, and automatically monitors, warns and even actively deals with information related to the elderly.

Compared with the traditional pension model, the advantages of smart pension in the service capacity, the use of information technology integration to improve the service quality and efficiency, improve the social security system from multiple levels; In terms of service forms, we will innovate social security forms at the family and community levels by using affordable and convenient pack-to-point service forms. In terms of service content, it can meet the multi-level needs of the elderly and extend the ability of artificial pension service.

Smart pension is an important part of the development process of smart city, and also an important practice and inevitable trend of smart city. Smart elderly care in China is developing rapidly, but there are still many problems to be solved at the present stage, including that its research is mainly limited to smart wearable devices, smart home and smart medical products. In addition, the Internet of Things, information security and other related technologies are still in their infancy, and even in some technical aspects are still relatively blank.

Nevertheless, various provinces and cities have done a lot of work in the aspect of intelligent pension, and actively develop urban intelligent pension service system based on information and technology.

In January 2017, Wuzhen launched the "Smart Elderly Care" online platform, which installs "smart home care equipment", "remote health care equipment", "SOS call fall and alarm positioning" for the elderly at home, and makes use of AliCloud server, WeChat, APP and other remote management

We will develop a smart environmental protection application system and innovate models for urban ecological and environmental supervision

In recent years, "urban diseases" such as traffic congestion, population expansion, environmental degradation and resource shortage have appeared in cities. It has become a new challenge for city managers to adopt reasonable and effective measures to deal with urban environmental problems. The development of smart cities has brought new opportunities to urban environmental governance.

"Intelligent environmental protection" is the product of the combination of Internet of Things technology and environmental information, and is the application of Internet of Things technology in the specific field of environmental protection. In order to meet the requirement of the new situation development, give full play to the huge role in the field of information technology in environmental protection, with the help of the Internet of things technology, the sensors embedded in various kinds of environmental monitoring object (objects), through the supercomputers and cloud computing will environmental protection field of Internet of things together, realize the human society and the environment of the integration of business system, with a more detailed and dynamic way to achieve environmental management and decision making "wisdom.

The application of intelligent environmental protection in urban management, governance and decision-making is of great significance. It can not only effectively deal with a series of environmental problems brought about by rapid urbanization, but also help to build a diversified urban governance system and realize effective information screening and information disposal. At present, intelligent environmental protection is mainly used in the fields of monitoring data collection and analysis, environmental quality and pollution source monitoring, hazardous waste mobile management, environmental emergency management, environmental quality simulation and evaluation system and so on.

When the concept of smart city was first proposed in 2009, smart environmental protection was tried to be applied and promoted, but the development of smart environmental protection in China is still in its infancy. With the continuous increase of government investment and the continuous promotion of Internet of Things technology, many cities have still made many achievements in the practice of smart environmental protection.

In January 2017, jining wisdom environmental regulation formal operation platform, data center platform based on intelligent city hardware equipment, access to all kinds of supervision and monitoring points, more than 10800 various types of data real-time updates daily, online monitoring street all environmental data, as of December 2017, the platform of the ecological environmental quality monitoring and pollution sources monitoring dynamic database contained waste gas, waste water, sewage, air quality monitoring information, such as more than 600 ten thousand, reported 56000 environmental events, complaint investigated irregularities since 650.

In August 2017, the government and the environmental protection of qinghai province to promote "Internet +" action and ecological environment construction of big data requirements, relying on the ecological environment data resource center has been built, built a "resource sharing, centralized management, dynamic control, business sense," the wisdom of the urban infrastructure, information technology and industry support ecological environment monitoring regulations, air quality forecast environmental risk monitor early warning, early warning, etc.

In October 2017, the general office of jiangsu province issued by the "jiangsu province ecological environment monitoring network construction implementation plan" proposed that by 2020, the province ecological environment monitoring network to achieve environmental quality, complete coverage of key pollution sources, ecological status monitoring, monitoring data of various levels system interconnection and sharing, initially built on land or sea as a whole, heaven and earth, and coordination, information sharing of the ecological environment monitoring network in the province.

The new era of artificial intelligence promotes the in-depth development of new smart cities

Artificial intelligence technology and its application development are changing people's way of life, and will promote the development of new smart cities in depth, showing three development trends in public service, urban governance and sharing economy.

Build a new wireless city and realize "one-stop" public services

Wireless city refers to the use of WiMAX, Wi-Fi and other low-cost wireless access technologies, combined with Skype and other VoIP technologies, to achieve the coverage of wireless network within the whole city, so as to provide faster wireless Internet services anytime and anywhere.

Smart city's requirements for infrastructure network layer are high broadband, wide coverage, massive data, mobile state and collaborative work. Wireless city construction based on optical cable, WLAN and 4G/5G solves the problem of infrastructure network construction in smart city. Wireless city can not only bring rich and colorful network life to smart city, but also bring powerful new driving force for social development. For example, when combined with modern service industry, wireless city can comprehensively enrich the business function of modern service industry, improve the knowledge content of modern service industry, and promote the rapid development of modern service industry.

At present, many large and medium-sized cities in China are actively building wireless urban networks to facilitate citizens' shopping, travel, study, education, health care and other aspects.

In January 2017, Shanghai planned to invest more than 30 billion yuan in the next three years to build a new wireless city, including network, platform, demonstration, industrial agglomeration and public service platform building.

In May 2017, Shanghai Municipality constructed a new wireless city framework, proposed to build a wireless broadband network system with optimized 4G network coverage and the first pilot deployment of 5G network, and built a public WLAN network service system with i-Shanghai as the core, realizing the goal of a broadband network system with gigabit access covering all urban and rural areas. Tongzhou District of Beijing has built 416 "My Beijing" free wireless Internet service outlets, successively opened 11 service halls for free wireless Internet service, and realized the basic coverage of 89 main roads, a total of 416 online sites. With the structural adjustment and transformation and upgrading of China's economy, new business forms have put forward new demands on the innovation of payment methods and provided a strong impetus for the rapid development of mobile payment. According to the 2017 China Smart Living Report, 84 percent of Chinese people don't carry cash when they leave home. It is reported that as of November 2017, the number of merchants receiving payment code by Alipay in Xi 'an has increased by 53%, and 76% of offline stores have connected to mobile payment.

In December 2017, the Xiamen Citizen Card APP was officially launched, which unified the electronic identity of citizens. Citizens can use the APP for credit riding, scanning QR code for payment, self-scanning for book borrowing and return, etc., and enjoy convenience in the fields of medical and health care, government affairs and life services. In 2017, Hangzhou became the "city of mobile payment" and carrying only a mobile phone became the new normal. "Bus card + Alipay + UnionPay cloud flash payment and mobile payment" was fully covered on all bus routes in the main urban area of Hangzhou.

Build a "city brain" to promote intelligent development of urban governance

"Urban brain" refers to the comprehensive use of big data, cloud computing, artificial intelligence and other new generation of information technologies to conduct dynamic real-time analysis of multi-source and multi-dimensional information of the whole city, achieve resource sharing and automatic deployment of public resources, and real-time correction of defects and problems in the dynamic operation of the city.

"City Brain" is an effective way to improve the quality of smart city development. The promotion of the construction of "City Brain" can improve the ability of smart city's livelihood service, monitoring and warning, emergency management, and dynamic planning and management. From the perspective of the architecture of "City Brain", IT mainly includes three levels: data resource platform, integrated computing platform and IT service platform. At present, the "City Brain" is mainly used in traffic control, crime prevention, people's livelihood monitoring and evaluation, public safety management and other aspects.

Many cities have carried out practice and exploration activities in the construction of "urban brain", which has accumulated rich experience and achieved remarkable results. Since the construction of "City Brain" in Hangzhou in October 2016, Alibaba has integrated and managed 128 signallight intersections in Hangzhou, and more than 100 intersections have realized unregulated signallights, saving 4.6 minutes of travel time on elevated roads. In the main urban area of Hangzhou, the average daily traffic incident alarm number reaches more than 500 times, with an accuracy rate of 92%, which greatly improves the efficiency and directivity of law enforcement. In February 2017, Suzhou signed a deepening cooperation framework agreement with Alibaba on the construction of "City Brain", aiming to reshape the urban management model with data thinking, improve the management level of the whole city, and create a new model of smart city. In August 2017, suzhou city brain "project has been gathering, gathering, cleaning, storage, involving public security, the city municipal, rail transportation, tourism, and the company department, the three carriers and the major Internet companies such as all kinds of data, the cumulative with historical business data of more than 3000 one hundred million, at the same time, through the data real-time transmission channel, gathering data every day 680 million, promote the development of intelligent city governance.

We will develop the "Internet Plus" industry and usher in a new era of the sharing economy

With the development of information technology and the mature application of mobile Internet, "Internet +" has had a revolutionary impact on all walks of life. It is in this context that the sharing economy has emerged and thrived. Sharing economy is based on Internet technology support, based on the network platform, to trust as a link, on the premise of owners living are not affected and formation of idle goods or personal resources use, housing, cars, skill and time to share the open exchange system, mainly presented by the use of modern information technology as the support, resources trading as the essence, the efficient use of resources as the goal the characteristics of the three aspects.

Sharing economy brings not only the change of consumption concept and consumption pattern, but also the more profound change is to accelerate the pace of green transformation of economy and society. At present, sharing economy is also accelerating to penetrate into many areas of people's clothing, food, living and livelihood, profoundly changing the way people produce and consume. The sharing economy covers education, health, food, logistics and warehousing, transportation, services, infrastructure, urban construction and finance.

Thanks to the rapid development of mobile Internet technology, it has become possible for people to share excess capacity, and the sharing economy has experienced substantial growth. The Sharing Economy Research Center of the State Information Center and the Sharing Economy Working Committee of the Internet Society of China jointly released the Annual Report on the Development of the Sharing Economy in China. The report shows that in 2017, the market turnover of the sharing economy in China was about 4,920.5 billion yuan, up 47.2% over the previous year. The number of sharing economy service providers reached 70 million, an increase of 10 million over the previous year. About 7.16 million employees were employed in sharing economy platforms, accounting for 9.7 percent of the new urban jobs that year.

By the end of 2017, there were 60 Chinese companies among the 224 unicorns in the world, including 31 companies with typical sharing economy attributes, accounting for 51.7 percent of the total number of Chinese unicorns. This shows that China has become the innovator and leader of the global sharing economy.

As a new thing in the field of sharing economy, shared bikes have attracted widespread attention from the public as soon as they come out. In August 2017, the Human Resource Strategy Conference and "Xianbuxiu" service providers' conference was held in Wuxi, with the theme of "Human Resource Sharing, Flexible Employment", to discuss the transformation and innovation of human resources under the sharing economy. Zhejiang Provincial Health and Family Planning Commission approved Hangzhou While-way Health and Medical Outpatient Department to carry out pilot sharing services such as Medical technology. In September 2017, the approved "While-way International Medical Mall" pilot provides Medical technology departments such as examination, pathology, ultrasound and Medical imaging, as well as shared services such as pharmacy and operating room. Shared hospitals are emerging all over the place.

05 conclusion

Internet of things, big data and cloud computing, artificial intelligence and so on the application of a new generation of information technology bring opportunities for the wisdom of city development, intelligent city is the advanced stage of development of city information, more industrialization, urbanization, information fusion depth, to solve the population expansion, shortage of resources, environmental pollution and traffic congestion, increasing public safety hidden trouble and a series of "city disease" provides a effective way.

As of June 2018, more than 500 cities in China have made clear plans to build smart cities. During the "13th Five-Year Plan" period, the new smart city with "Internet + government affairs" as the core will further improve the ability of fine management and precise governance of the city, promote the improvement of urban function and quality, promote the innovation of government information management, and promote the new development of urban economy.

At present, the theoretical research and practical exploration of China's new smart city are only in the initial stage, and it is of great significance to study the current situation of smart city construction. Based on the framework and evaluation system of new smart city construction, this study analyzes the current situation of new smart city construction in China, including the continuous favorable policy environment, the innovative development of infrastructure, the continuous expansion of application system, and the in-depth development of smart city promoted by artificial intelligence.

However, the new smart city is a strategic complex system engineering, and there are still many problems in the construction. The construction and development of new smart cities should be further discussed and improved from the aspects of top-level design, network security and construction timing.

Top level design. Different regions have different understandings of smart cities and different construction methods, which may easily lead to information isolation islands. Therefore, it is necessary to introduce corresponding construction plans and guidance programs at the national level to guide the construction of smart cities in different regions.

Cyber security. New smart cities greatly rely on the use of new technologies such as the Internet of Things, cloud computing, big data, artificial intelligence, etc. Security problems are more serious than in the era of digital cities. Therefore, it is necessary to establish and improve the information network security guarantee mechanism and technical system to ensure the safe and stable operation of new smart cities.

Construction timing. The short-term construction planning of smart cities should focus on the construction of basic networks and systems such as the Internet of Things and information technology. The medium and long-term planning should gradually expand the application fields of smart cities and improve the functional quality and sustainable development capacity of cities.
