Abstract:

【Purpose/significance】To construct a national science and technology (R&T) security risk assessment system, which is es⁃

sential for analyzing national science and technology threats, grasping the entire national security posture, and managing national secu⁃

rity risk.

【

Method/process】The national science and technology security risk assessment index system, which covers four aspects of

R&T achievements, R&T talents, R&T activities, and R&T environment, is established based on the overall national security concept

and existing research, and the comprehensive weights of the indexes are calculated by integrating the hierarchical analysis method and

entropy weighting method based on the game theory combination assignment method. Meanwhile, the fuzzy Borda method was applied

to evaluate the combination of the linear weighted assessment model, TOPSIS assessment model, grey relational assessment model,

principal component assessment model and particle swarm optimization projection tracing assessment model, and the national science

and technology security risk portfolio assessment model was constructed

.

【Result/conclusion】The research results show that the risk of

national science and technology security has shown a decreasing trend year by year in the past 10 years, and the importance of S&T tal⁃

ents, S&T achievements, S&T environment and S&T activities decreases. The model can provide reference value for national science

and technology security risks management.【Innovation/limitation】The game theory portfolio assignment method is used to determine

the index weights, and the fuzzy Borda method is applied to the combination of five single assessment models, which makes the na⁃

tional science and technology security risk assessment results more scientific and accurate.
