New infrastructure construction (referred to as: new infrastructure), mainly including the construction of 5G base stations, ultra-high voltage, intercity high-speed railroads and urban rail transit, charging piles for new energy vehicles, big data centers, artificial intelligence, industrial Internet seven major fields, involving many industrial chains [2], is the concept of new development, driven by technological innovation, based on the information network, and oriented to the needs of high-quality development to provide Digital transformation, intelligent upgrading, integration and innovation services infrastructure system. Compared with the original infrastructure, the new infrastructure focuses more on the direction of high technology and artificial intelligence, and the past is not quite the same as the road, railroad and basic social facilities, and it is more the construction of digital China, which will be the main theme and the main tone for a long time to come. The first information infrastructure. What we know better is the construction of communication networks represented by 5G base stations, in fact, there are also new technology infrastructures represented by artificial intelligence and blockchain, and finally the arithmetic infrastructure represented by data centers and intelligent computing centers, and so on. Second, convergence infrastructure construction. This is a little complicated to understand, because this is upgraded and transformed on the basis of the original. To make an analogy, our traditional transportation communication will become intelligent transportation infrastructure through upgrading, which is the representative of convergence infrastructure construction. Third, innovation infrastructure. This part we can understand as innovative technology and artificial intelligence, high-tech incubators and learning centers. The main role is for learning and guiding cutting-edge technology to provide a solid theoretical and talent base for the development above.
