Intensive construction of new infrastructure to support high-quality urban development

In the information age, new infrastructure is an important and decisive factor for high-quality urban development, providing a solid foundation for building a cyber power, a digital China and a smart society. At present, China's new infrastructure has played an important role in the process of urban economic and social development, but there are also problems such as repetitive construction, blind investment, greed for innovation, and low input-output ratio. It is necessary to coordinate the construction of new infrastructure from four aspects: top-level design, demand traction, mining characteristics, and long-term operation. We will give full play to the role of new infrastructure in supporting high-quality urban development.

First, the new infrastructure plays a significant role in supporting high-quality economic and social development

Since the 18th National Congress of the Communist Party of China, China has successively deployed development strategies such as broadband China, network power, digital China and smart society at the national level, which have greatly promoted the construction and development of information infrastructure. According to the "Digital China Development Report (2020)", during the "13th Five-Year Plan" period, China's information infrastructure construction scale is leading the world, and the world's largest optical fiber network and 4G network have been built. By the end of 2020, the number of Internet users has reached 989 million, the Internet penetration rate has reached 70.4%, and 718,000 5G base stations have been built. 5G terminals connected more than 200 million data. In addition, the construction of integrated infrastructure, represented by the digital transformation of infrastructure in the fields of transportation, water conservancy, energy, and municipal administration, has continued to accelerate, making the city's perception ability and thinking level achieve a leap forward, innovative infrastructure has strongly supported science and technology research, and the national major science and technology infrastructure has played a leading role in scientific and technological innovation and economic development.

From the perspective of urban development, the scientific and rational layout and effective application of new infrastructure plays a fundamental role in improving the energy efficiency of urban management, the level of service and the quality of economic development. In the short term, the investment and construction of new infrastructure plays a positive role in stabilizing investment, expanding domestic demand, increasing employment and driving economic growth. 5G base stations, smart charging piles, and data centers have become hot spots for planning and investment construction. New business forms and new models enabled by new infrastructure have flourished. Help enterprises to resume work and production; Online shopping and unmanned distribution ensure the efficient circulation of the domestic consumer market. In the long run, the new infrastructure itself is the meaning of high-quality urban development, which is conducive to deeply empowering the modernization of urban governance system and governance capacity, promoting the facilitation and inclusiveness of social services, the application of urban integrated management service platform has improved the city's perception, thinking, and emergency response capabilities, and the cross-provincial communication office and the one-Netcom office have facilitated the mass enterprises from the government service side. Smart medical care and smart education make it possible to realize cross-regional and cross-level flow sharing of scarce resources. The changes in industrial structure brought about by the construction of new infrastructure and the concentration of high-end factors promote the optimization of local industrial environment, the reshaping of industrial structure and the construction of innovation ecology, and the new infrastructure has become an inevitable choice to enhance the core competitiveness of the future development of cities.

Second, local governments are speeding up the construction of new infrastructure, but there is also the problem of duplication of investment

Due to the construction of new infrastructure and the localization of services, local governments have become the main body of planning and important participants in investment and construction, hoping to accelerate economic and social transformation and development through the construction of new infrastructure. At the provincial level, the "2020 White Paper on the Layout and Development of New Infrastructure in Chinese Cities" released by CCID Research Institute shows that the number of new infrastructure projects in Anhui, Guangdong and Jiangsu, the top three in the country, reached 280, 165 and 109, respectively, and Chongqing focuses on new infrastructure construction from 2020 to 2022. In accordance with the principle of "mature batch, start batch, reserve batch", we will focus on promoting 7 major sectors, 21 special projects, and 375 projects, with a total investment of 398.3 billion yuan. The proportion of new infrastructure in Hebei, Shandong and Guangdong is as high as 43.5%, 35.0% and 34.1%. At the city level, Hefei proposes to implement no less than 200 new key infrastructure projects from 2020 to 2022, with a total investment of no less than 200 billion yuan; Kunming has proposed 394 key projects focusing on new infrastructure such as 5G, data center, artificial intelligence, industrial Internet and Internet of Things, with a total investment of 1001.18 billion yuan, of which 58.984 billion yuan is planned to be completed in 2020; Guangyuan City has specified that from 2020 to 2022, 70 new infrastructure projects will be implemented, with a total investment of 17,642.27 million yuan.
