Abstract: Developing new infrastructure plays a crucial role in enhancing the security protection capabilities of critical information infrastructure. The approaches adopted by relevant countries in advancing new infrastructure—such as boosting global competitiveness, prioritizing key technology R&D, attracting deep private sector participation, promoting unified standards and regulations, and strengthening supply chain resilience—offer valuable insights. Although China’s new infrastructure has seen continuous improvements in recent years regarding development scale, technological autonomy, digital and intelligent capabilities, and its capacity to support critical infrastructure, it also faces challenges such as significant intrinsic security risks, risks associated with introducing new technologies, and lagging standardization efforts. It is recommended in terms of to drive the highquality development of new infrastructure by leveraging intelligent upgrades as the driving force, functional expansion as the connecting link, and boundary governance as the focal point.

Key words: new infrastructure, critical information infrastructure, security threats, security protection, highquality development
