This paper uses the large sample questionnaire survey on Shaanxi Province and structural equation model to discuss the relationship among the psychological contract of the core military enterprises and network members, cooperation satisfaction and the network stability, from the perspective of technology innovation network in military-civil industry integration. The results show that the psychological contract between the network member and the core military enterprise is composed of three dimensions such as transaction-oriented, relation-oriented and development-oriented. The fulfillment of the psychological contract has a significantly positive impact on the innovation network stability.
