Abstract：Technology is a“critical element”for national competitiveness and strategic security,and high standard sci-tech security serves as a prerequisite and guarantee for high-quality development.This paper constructs a research framework for assessing sci-tech security levels and conducts an empirical study on 31 Chinese provinces and municipalities via global principal component analysis.The alignment and weighting of underlying indicators with three sci-tech security subsystems are explored,and the temporal evolution trends and the trajectory of the center of sci-tech security across provinces and municipalities are analyzed.The main findings are as follows:①From 2010 to 2023,the overall sci-tech security level in all provinces and municipalities showed a steady upward trend,characterized by a distribution pattern of“higher in the east and lower in the west,stronger in the south and weaker in the north”;②The 31 provinces and municipalities were classified into three types-leading,developing,and weak-with significant gradient differences observed in their scores on the innovation input subsystem of sci-tech security;③During the study period,the center of China's provincial sci-tech security was observed to shift southeastward,with the migration speed following a non-linear trend of first decreasing,then increasing,and subsequently declining again.This indicates that sci-tech security levels gradually increased from west to east and from north to south,thereby exacerbating regional imbalances.The findings reveal the evolutionary characteristics of sci-tech security levels across China's provinces, providing a robust theoretical and decision-making basis for advancing China's sci-tech security risk monitoring,optimizing its spatial configuration,and implementing its national security strategy.
