Abstract Guided by systems theory,this paper constructed a provincial-level science and technology security evaluation index system.The system encompasses internal factors such as the integrity of the scientific and technological system,control capability over core technologies,independent innovation capacity,and risk resistance capacity,along with external environmental variables including international scientific-technological cooperation and competition,economic and trade conditions,legal environment,and socio-cultural factors.The science and technology security levels of China's provincial administrative units from 2018 to 2022 were assessed.The weights were assigned and evaluated using the entropy weight method and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS).The results reveal that during the study period,provincial science and technology security levels exhibited an overall spatial pattern of“higher in the east and lower in the west;stronger in the south and weaker in the north.”Beijing,Guangdong,Jiangsu,and other coastal regions emerged as prominent“high-high agglomeration zones.”Moreover,spatial correlation analysis indicates a general positive correlation among regional science and technology security levels across China,though the autocorrelation gradually weakened over time.

Key words： Provincial dimension Science and technology security Spatiotemporal difference Entropy-TOPSIS method
