Abstract

Critical infrastructures are vital strategic resources, directly impacting national security and the operation of economy and society. Twenty-two megacities and large cities in China, due to the concentration of resources and poorly concealed distribution of critical infrastructure, face multiple risks such as warfare attack, natural disaster, and facilitiy aging. Incorporating the undergroundization of critical infrastructure into national strategy is an imperative choice for national security, resilient city, and high-quality growth. International practices have proven the advantages of underground development in terms of protection and space optimization. During the 15th Five-Year Plan period, it is recommended to adopt strategies such as strengthening top-level design, coordinating planning and management, launching pilot demonstrations, and promoting innovative and integrated development, so as to establish a new paradigm for the development of Chinese super-large and mega cities and consolidate the foundation for urban safety and development.
