Core technologies subject to foreign countries have become the top priority of China's economic security. The issue of techno-economic security needs urgent attention. This study draws on the concepts of "sensitivity" and "vulnerability" from interdependence theory, and proposes four categories of attributes and corresponding indicators of technological sensitivity, economic sensitivity, technological vulnerability and economic vulnerability for China's industrial sectors based on the perspective of techno-economic security. Factors of sensitivity and vulnerability are extracted using the factor analysis method and 38 industrial sectors are divided into four categories:High sensitivity and high vulnerability, high sensitivity and low vulnerability, low sensitivity and high vulnerability, low sensitivity and low vulnerability. This classification can provide a basis for conducting classified monitoring and evaluation of the techno-economic security status of various industries as well as for better safeguarding national economic security.
