The introduction of physics coupling interaction theory into the measurement of civil -military integration level in military enterprises is of great significance to the study of civil-military integration. First，This article defines the concept of civil -military coupling interaction; Secondly, it refines the the measurement dimension of civil-military coupling interaction, and develops the scale; Thirdly,based on the analysis of reliability and validity ,it tests and adjusts the scale.The results show that the civil-military integration can be measured effectively from 6 aspects, namely, corporate culture coupling, organization and mechanism coupling, product and technology coupling, standard coupling, information coupling and personnel interaction. Based on this, it puts forward some advice for the military enterprises to promote military- civilian integration strategy.
