Abstract: In the context of regarding the depth development of civil-military integration(CMI) as a national strategy, civil-involved military has become the most important models of the civil-military integration collaborative innovation. This paper extracts 18 influencing factors of the knowledge transfer in civil-involved military by combing the relevant literatures. On this basis, we find five types of main factors such as integration environment, innovation subject, operation mechanism, subject interaction and cooperation obstacle by using exploratory factor analysis. The article builds the influencing factors model of the knowledge transfer in civil-involved military process under the perspective of civil-military integration collaborative innovation. Meanwhile, we apply the structural equation model and the factor analysis method to verify hypotheses and corrections combined with the questionnaire data. The research results show that: a good integration environment, operation mechanism, innovative subjects, subject interaction have significant positive influences on the performance of knowledge transfer in civil-involved military process. Conversely, cooperation obstacle has a significant negative effect on the performance of knowledge transfer; Operation mechanism has positive impact on subject interaction. Integration environment and operation mechanism effect on cooperation obstacles are negative; Specially, operation mechanism is the greatest factor to the performance of the knowledge transfer in civil-involved military process and it plays the key boosting role in transfer process.
