Infrastructure is the backbone of a city and the lifeline of its security and development. Recently, the General Office of the Communist Party of China Central Committee and the General Office of the State Council issued the "Opinions on Promoting the Construction of New Urban Infrastructure and Building Resilient Cities", which clearly stated the need to "promote the construction of digital, networked, and intelligent new urban infrastructure". Under the new situation, using cutting-edge technology to promote the digital transformation of infrastructure has become a necessary path for cities to strengthen their muscles and bones. Currently, the technology and level of urban infrastructure construction in China continue to improve, and the total amount of infrastructure has significantly increased. As of 2024, the built-up area of urban areas in China exceeds 60000 square kilometers, with a water supply pipeline length of 1.103 million kilometers, a drainage pipeline length of 913500 kilometers, a natural gas pipeline length of 980400 kilometers, a heating pipeline length of 493400 kilometers, and a total operating mileage of rail transit exceeding 10000 kilometers. The urban space has formed a massive and interconnected infrastructure system. At the same time, due to the aging of infrastructure, rust and microbial growth on the inner walls of water supply networks, as well as exposure, displacement, and even leakage of pipelines, problems occur from time to time. The disaster bearing capacity of urban infrastructure is clearly insufficient, which poses significant safety hazards to the normal operation of society and people's work and life. Practice has shown that the digital transformation of urban infrastructure can not only safeguard urban safety, but also become a "new trend" for the development of related industries. Hefei not only promotes the construction of digital urban infrastructure, but also strengthens the urban lifeline safety industry cluster through "government industry university research" cooperation, making the urban "lifeline" a "new engine" for development; Foshan City uses digital means to monitor urban water supply, drainage, gas, heating, comprehensive pipe galleries, bridges and other infrastructure in real time, connecting the "neural tentacles" of urban perception, drawing a "panoramic portrait" of infrastructure operation, and successfully handling tens of thousands of gas leaks, ground collapses and other alarm situations; Wuxi city has achieved synergy among people, vehicles, roads, and cloud through improved infrastructure, with a network control rate of over 95% for 2756 intersection signal lights in the main urban area. This has been used as an opportunity to promote cluster development. From the practices in these cities, we see the enormous potential of new infrastructure construction. Digitization provides a "thousand mile eye and a smooth ear" for the operation, maintenance, and management of urban infrastructure. Various regions need to accelerate the construction of infrastructure data platforms, connect cross industry and cross departmental "data chimneys", establish a big data base that aggregates all types of infrastructure, create a "one map" platform for panoramic visualization of urban infrastructure, and achieve intelligent operation, maintenance, and management of infrastructure. Efficient organizational linkage is the key to the construction of digital infrastructure. The construction and management of urban infrastructure involve numerous departments, and whether data applications can receive coordinated responses from organizations determines the effectiveness of digital transformation of infrastructure. Each region needs to clarify the rights and responsibilities of data providers, managers, and users, establish a "responsibility matrix" of comprehensive management departments, industry regulatory departments, and ownership responsible units, refine the responsibility list for the entire process of "operation and maintenance supervision, graded warning, disposal intervention, and emergency dispatch", and eliminate the "responsibility ambiguity zone" in infrastructure operation and maintenance supervision. The construction of digital infrastructure requires huge investment, as well as high post operation and maintenance costs and system upgrade iteration costs. To make the construction of digital infrastructure sustainable, we need to consider the long-term strategy of "doing big things with small money". Each region should avoid duplicate investment, adhere to the principle of "utilizing old and current", make good use of existing systems, and use resources on the "cutting edge". At the same time, following the principles of controllable risks and commercial autonomy, we will promote the establishment of a diversified investment and financing system, clarify the rights and responsibilities of all parties in various stages such as investment, construction, management, operation, and maintenance, and reduce the financial burden on the government. In addition, we need to leverage the agglomeration advantages of urban agglomerations, create a distributed network with multiple centers radiating, and achieve wider digital service coverage with limited resources. Whether the people are satisfied is the standard for testing the effectiveness of digital infrastructure construction. The digital transformation of infrastructure should focus on improving people's livelihoods and promoting sustainable urban development. Only by closely adhering to the needs of citizens' lives and social development, and eliminating the "quick success and instant benefits" political achievement concept, can we continue to strengthen the backbone of urban safety and high-quality development, truly empower urban resilience construction, and promote urban safety development.
