Abstract: One of the common reasons for the financing difficulties of modern enterprises is that there is information asymmetry between investors and financiers, which can easily lead to "adverse selection" or "moral hazard", so to a certain extent, it will become an obstacle to the cooperation between the two sides. In view of this practical problem, this paper proposes the cooperation strategy to improve the success rate of enterprise financing. The concrete measure is that the information asymmetry between investors and financiers can be effectively reduced by strengthening their communication and exchanges to enhance their mutual trust and understanding. When the two sides reach a consensus on the expected benefits and risks, and agree on the distribution scheme of benefits (i.e., benefits generated by cooperation or reduction in costs), the two sides will make rational choices and are more willing to cooperate, which means that the success rate of financing transactions will be successfully improved. In addition, the feasibility of the cooperation strategy is partially verified by using the mixed model of non-cooperative game and cooperative game, combined with the methods of conditional enumeration and numerical solution. Furthermore, the effectiveness of cooperation strategy proposed in the paper is proved by using the mixed model of non-cooperative game and cooperative game, and the enumeration cases are partially verified by means of the numerical solution method. The results show that cooperative strategy in the process of financing game is beneficial to improving the success rate of enterprise financing.
