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

摘要： 发展新型基础设施对提升关键信息基础设施安全防护能力具有重要推动作用.相关国家提高新基建全球竞争力、注重关键技术研发、吸引私营部门深度参与、推动标准规则统一、提升供应链韧性等发展新型基础设施的做法具有一定借鉴意义.尽管近年来我国新型基础设施在发展规模、技术自主程度、数智化水平以及支撑关键信息基础设施能力上不断提升，但也面临着自身安全风险较大、新技术引入风险、标准制定滞后等挑战，建议以智能化升级为动力、以功能扩展为纽带、以边界治理为重点，着力推动新型基础设施高质量发展.
