Abstract: The instability of the cooperation between the two parties is caused by the low service quality of the franchisees, their own affairs, the weak headquarters management and so on. Based on the evolutionary game model as the main theoretical tool, this paper develops an interactive evolutionary game system for expressing the behavior of company headquarters and affiliates under incomplete information.By solving Jacobian matrix, the influence of the change of initial conditions and decision parameters on the evolutionary stability results is revealed. Then, taking Stoexpress as an example, the numerical simulation is carried out by using MATLAB software. The results show that the system presents three evolutionary stable results and a periodic stochastic state when franchisors cooperate actively, and when the revenue, the fines, the degree of information asymmetry and the cost of supervision are located in different thresholds. Meanwhile, it is found that the unit price has a positive effect on the cooperation stability of the two parties. Finallyreducing the service cost of express franchisees and improving the quality of service, establishing a moderate penalty system for breach of contract and improving the profitdistribution mechanism, strengthening the information sharing of the platform and promoting the transparency of information, and creating a good competitive atmosphere and avoiding unnecessary price warfare will help guide the evolution of the system to the ideal state.
