The military supply chain finance is an important driving force to ensure the stable and efficient development of the military supply chain. The existing military supply chain finance has some problems, such as poor information cooperation, which seriously restricts the development of the military supply chain finance business and limits the development of the military industry to a certain extent. For this problem ，an evolutionary game model of cooperation was constructed among government guidance, military core enterprises and military supply chain financial service platform. The strategic choice of the three parties in the military supply chain financial information cooperation was analyzed. The research shows that the willingness of the three parties to cooperate has an impact on each other. Different government support methods have different degrees of impact on the military core enterprises and the military supply chain financial service platform, and the degree of information cooperation between the military core enterprises and the platform has a great impact on the platform.
