In order to explore the present situation and development trend of science and technology security research, this paper makes comprehensive analysis and comment on the research of science and technology security at home and abroad from the elements, structure, function and external environment of science and technology security based on system theory. The research shows that science and technology security has strong integrity, hierarchy and linkage, and future research should focus on the governance of science and technology security, the construction of science and technology security early warning and monitoring system, the impact and evaluation of science and technology security on the overall national security.
