Abstract: Through the actual investigation, it is found that the cross-border e-commerce logistics alliance has the following problems in the operation: First, the language of China’s information system is mainly Chinese, and it is inconsistent with the conversion format, data table processing, concept and other standards of foreign information systems. Second, due to cross-border and cross-regional restrictions, it is difficult to integrate information resources between alliance enterprises, which led to the phenomenon of “information islands”, and it is difficult to track international logistics information in real time. A cross-border e-commerce logistics alliance model is proposed based on information collaboration to promote the effective integration of cross-border information systems, the seamless connection of cross-border electronic documents, and the real-time transmission and sharing of cross-border information. Then the evolutionary game theory is used to analyze the dynamic game process between cross-border e-commerce platforms, domestic logistics company and foreign logistics company, and a tripartite evolutionary game model based on information collaboration is constructed. Based on the investigation of enterprises and experts, system dynamic is used to simulate and analyze the dynamic game process of the three-party information coordination selection. The results show that: (1)Only when the information collaboration standardization level is higher than 0.47, can we promote cross-border logistics alliance members to choose information collaboration strategies. (2) Compared with other factors, the three parties of the alliance are the most sensitive to the impact of information collaboration risk, and the convergence speed of strategy selection is the fastest. (3) Equalized income distribution can further promote the choice of alliance members’ information coordination strategies. If the income distribution coefficient of the cross-border e-commerce platform is higher than 0.7, information coordination will be difficult to implement. (4) Compared with other alliance members, domestic logistics companies are more sensitive to the four influencing factors of information synergy.
