As of July 2025, the total number of charging infrastructure in the country will reach 16.696 million, achieving the ratio goal of "one charging gun for every three new energy vehicles", and core regions such as the Yangtze River Delta have been selected "Two hours in line" upgrades to "plug and go". The policy side continues to increase: the state promotes the construction of "counties and counties have charging stations", and Hubei Province has made it clear that 600,000 charging piles will be built in 2025, forming "urban area 3" km, 6 km in towns and villages" service radius; Beijing gives 300 per kilowatt to supercharging stations Yuan construction subsidy, Shanghai implements preferential electricity prices for public pile operation service fees. At the same time, the industry standards are further refined, and electrical safety requires that the insulation resistance of AC piles is not less than 10MΩ, DC piles are not less than 20MΩ, and the grounding resistance needs to be lower 0.1Ω, and the communication protocol is fully compatible with GB/T 27930 and ISO 15118 (supporting V2G bidirectional charging), promoting the upgrading of the charging ecosystem to "safe and intelligent".

　　1. Expansion of infrastructure scale: from "quantitative change" to "qualitative change"

　　At present, our country's infrastructure construction is undergoing a new round of expansion and upgrading. In addition to the traditional "iron public foundation" field, the construction of new infrastructure such as 5G base stations, UHV, new energy vehicle charging piles, and big data centers has become a key direction. According to statistics, in the first half of 2023, new major infrastructure projects increased by 23% year-on-year, of which new infrastructure accounted for more than 35%. This change is not only reflected in the expansion of investment scale, but also reflects the forward-looking layout of the industrial structure.

　　2. Upgrade the standard system: escort high-quality development

　　With the expansion of infrastructure scale, the construction of the standard system has accelerated simultaneously. The newly released "National Infrastructure Construction Standard System (2023 Edition)" has added 8 special standard modules such as green construction, intelligent operation and maintenance, and resilient cities. In a cross-river bridge project, the newly promulgated "Technical Specifications for Bridge Health Monitoring" has increased the efficiency of structural monitoring data collection by 40% and the accuracy of early warning by 25%. The improvement of the standard system is providing strong support for project quality, safe operation and sustainable development.

　　3. Policy and market coordination: build a new pattern of benign development

　　The synergistic effect between policy guidance and market mechanism is becoming increasingly prominent. The recently issued "Infrastructure REITs Expansion Rules" has effectively revitalized existing assets, and the average premium rate of the first batch of 9 infrastructure REITs products has reached 15%. At the same time, through the establishment of a three-level project early warning mechanism of "red, yellow and green", the dynamic supervision of major infrastructure projects across the country has been realized. This model of "policy guidance + market operation + standard constraints" is promoting the formation of a healthier and more sustainable development ecology in the infrastructure industry.

　　4. Future prospects: smart integration and green transformation

　　In the next stage, infrastructure development will show two major trends: first, the deep integration of digitalization, and the application rate of BIM technology will increase from the current 45% to 70% in 2025; Second, greening has been comprehensively accelerated, according to the latest plan, the proportion of green building materials used in new projects needs to reach more than 60%. These changes indicate that infrastructure construction is undergoing a comprehensive transformation from simple functionality to intelligent and low-carbon.
