Smart cities use information and communication technologies to sense, analyze and integrate the key information of the core urban operation system so as to intelligently meet the various needs including livelihood, environmental protection, public safety, urban services and industrial and commercial activities response. The concept of smart city entered China in 2010. By the end of 2015, the number of smart city construction in China has reached 386. With the smart city into reality, will bring a huge market size. Qiao Run-Ling, deputy director of the Development and Reform Commission Urban and Small Towns Reform and Development Center, has said that Smart City is a superposition of countless "Internet +". Internet + transportation, Internet + education, Internet + medical, these add up to form a huge system of smart cities. Therefore, the smart city has huge market space. Ministries and actively promote the development of things Yang Xianwu, deputy director of the Department of High and New Technology Development and Industrialization of the Ministry of Science and Technology, said at the "2016 International Umoja Technology and Standards Summit and W3C World Wide Web of Things Task Force Meeting" on the 11th that the Ministry of Science and Technology will continue to support the Internet of Things And industrial development. In the Ministry of Science and actively promote key R & D programs, the key projects of the Internet of Things and smart cities are expected to start implementation this year. "Strive to make some breakthroughs in cutting-edge technology layout and major core technology research to enhance the core competitiveness of China's Internet of Things technology." Yang Xianwu said. According to the current policy, the key special projects will organize the strengths of industry, university and research institutes to work together to tackle key issues and put forward overall solutions. The implementation of this special key project will have a huge impetus effect on the industrialization of the Internet of Things. "This means that the evolution period of 'IoT technology' to the 'Internet of Things market' will be greatly shortened, and the technological renewal and achievement transformation will be faster due to the vague boundaries of various IoT development stages," said the insiders. At the meeting on the same day, officials from the Ministry of Industry and Information Technology also expressed their attitude of "escorting" the Internet of Things for R & D of enterprises. Lu Xi, deputy director of the Ministry of Industry and Information Technology Department of Science and Technology, said the next step will be the government as the guide to the business as the main body to focus on building a cloud computing, big data and other new industry integration innovation ecosystem. Ministry of Industry and Information Technology will support the development of all kinds of networking technology industry alliance, the effective integration of upstream and downstream industry chain collaborative innovation. Smart city will drive countless "Internet +" IoT technology will make a lot of dream come true, smart city is one of the most likely to be the first to enter reality. Smart cities use information and communication technologies to sense, analyze and integrate the key information of the core urban operation system so as to intelligently meet the various needs including livelihood, environmental protection, public safety, urban services and industrial and commercial activities response. The concept of smart city entered China in 2010. By the end of 2015, the number of smart city construction in China has reached 386. However, traffic congestion, air pollution and urban waterlogging are still serious problems. Smart cities are not wise. The industry believes that smart city "not smart" reason is that there is a lack of data sharing between departments and applications. For a long time, "fragmentation" between departments has caused "information silos". In particular, some vertical information systems are limited to internal departments. In response, Lloyd said the MIIT will promote a number of integrated application solutions in the areas of manufacturing, modern agriculture, smart home, and health services to form a batch of large-scale and unique data opening and sharing mechanisms. "The Ministry of Industry and Information Technology will also support service providers in key areas such as the Internet, chip manufacturing and equipment manufacturing, speed up the iteration of related technical standards and products, keep mature solutions and keep declining costs, and promote the large-scale development of IoT applications."
