Abstract: Science and technology security is an important part of China's national security system, and science and technology elements play a key role in supporting and ensuring national security. From the perspective of national security, this paper analyzes the evolution and connotation characteristics of the concept of science and technology security, analyzes and puts forward the judgment criteria and internal logic of science and technology security issues, and uses the case of " Neck Sticking" problem to prove it. On this basis, this paper uses the method of system element analysis to study and construct the science and technology security system in the New Era. The results show that the science and technology security system consists of four main components, including the subsystem of science and technology security components, the subsystem of science and technology security output, the subsystem of science and technology security environment and the subsystem of science and technology security governance, which together constitute the national science and technology security system.

摘要： 科技安全是我国国家安全体系的重要组成部分，科技要素在支撑保障国家安全中发挥关键作用。本文从国家安全视角对科技安全概念演化和内涵特征进行解析，分析提出科技安全问题的研判标准和内在逻辑，并以“卡脖子”问题案例加以佐证。在此基础上，本文利用系统要素分析方法研究构建我国科技安全体系，结果表明：科技安全体系主要包括科技安全构成要素子系统、科技安全输出子系统、科技安全环境子系统和科技安全治理子系统等四个主要组成部分，其共同构成国家科技安全体系。
