New infrastructure construction from the perspective of high-quality development

The new infrastructure should be the infrastructure of the new urbanization and support the high-quality urbanization strategy

Along with the process of industrialization, the process of urbanization will continue to advance, which is a universal law of modernization. With the deepening of China's new industrialization process, China has also begun to continuously promote new urbanization. In March 2014, the Central Committee of the Communist Party of China and The State Council issued the National New Urbanization Plan (2014-2020), which clearly pointed out that we should closely focus on comprehensively improving the quality of urbanization. We will follow a new urbanization path with Chinese characteristics that puts people first, synchronizes the four modernizations, optimizes layout, promotes ecological progress and inherits culture. Urban development requires a large number of inter-city and intra-city infrastructure, urbanization requires a large number of infrastructure construction, and new infrastructure should also meet the requirements of new urbanization. High-quality economic development requires the "four modernizations" development, that is, the deep integration of new industrialization and information technology, and new urbanization should interact with new industrialization, and urbanization should be coordinated with agricultural modernization. In a broader sense, the new infrastructure should be the infrastructure of the "four modernizations" development, not only to meet the requirements of the deep integration of new industrialization and information technology, but also to meet the requirements of benign interaction between urbanization and industrialization, and coordination with agricultural modernization.

Specifically, the requirements of new urbanization can be reflected in the construction of smart city, green city, forest city, sponge city, humanistic city, livable city and a series of types of modern city requirements, but also reflected in the requirements of urban agglomeration, metropolitan area construction, these requirements are also the goal of high-quality urbanization strategy. "New infrastructure" is to build infrastructure that meets the requirements of modern cities, urban agglomerations and metropolitan areas. To support the high-quality urbanization strategy, "new infrastructure" on the one hand, the layout of a new information, intelligent, green urban infrastructure, such as a new generation of intelligent information network, including F5G (gigabit fiber broadband), 5G, Internet of Things, cloud computing, edge computing, new Internet exchange center; On the other hand, the new generation of information technology and green technology is used to integrate with traditional urban infrastructure such as transportation, energy and water conservancy, municipal administration, environmental protection, and public health, and the traditional urban infrastructure is constructed by digitization, networking, intelligence, and green upgrading. For example, through the deep integration of information technology and traditional infrastructure, the formation of industrial Internet of Things, vehicle networking, power Internet of things, city perception facilities, intelligent municipal management, etc. 

The high-quality urbanization strategy not only includes the development of single towns, but also includes the development of urban agglomerations and metropolitan areas. The spatial structure of China's economic development is undergoing profound changes, and central cities and urban agglomerations are becoming the main spatial forms carrying the development factors. There is a great demand for infrastructure construction in urban agglomerations and metropolitan areas in the future, which includes high-speed, convenient, green and intelligent transportation infrastructure construction between cities in urban agglomerations, as well as transportation, information and other infrastructure and various public facilities between cities and suburbs in metropolitan areas, central cities and satellite cities. In short, supporting the new urbanization strategy will be a main battlefield for "new infrastructure".

The new infrastructure should be the infrastructure of a modernized economic system and adhere to supply-side structural reform

China's economy has shifted from high-speed growth to high-quality development, and the corresponding economic system also needs to shift from the traditional economic system to the modern economic system, and the construction of a modern economic system is an inevitable requirement for high-quality development. Modern economic system inevitably needs modern infrastructure, information, intelligent, green are the direction and requirements of modernization, therefore, the new infrastructure is modern infrastructure, constitute the infrastructure of the modern economic system. The key contradiction restricting the transformation of the traditional economic system into a modern economic system is that the quality of the supply side is not high. To build a modern economic system, we need to improve the quality of the supply of the economic system, and we need to eliminate ineffective supply and increase effective supply to better meet demand. Similarly, to build a modern economic system, it is necessary to carry out infrastructure innovation through "new infrastructure", so as to improve the quality of infrastructure supply, promote the development of digital economy, smart economy and green economy, and then promote economic transformation and upgrading, so as to achieve the goal of supply-side structural reform.
