The emergence of cross-border e-commerce has brought new opportunities to traditional enterprises. This paper discusses the partner selection of cross-border e-commerce companies in the B2B mode. It constructs a theoretical model of partner selection of cross-border e-commerce enterprises based on literature review. Through the mathematical analysis of an asymmetric evolutionary game model, it is considered that the model has an evolutionarily stable strategy. Based on it, a multi-agent model is constructed. The results of the simulation reveal the mediation role of trust between corporate reputation and enterprise cooperation. Simultaneously, it verified the moderation effect of information sharing between the trust and cooperation of cross-border e-commerce companies. It also provides explanations for the inconsistency in the relationship between trust and cooperative behavior. From both mathematical and data perspectives, this paper attempts to test the theoretical model proposed, which enriches the methodology to test the theory.

跨境电子商务的出现为传统企业带来了新的机遇。本文讨论了B2B模式下跨境电子商务公司的合作伙伴选择。在文献综述的基础上，构建了跨境电子商务企业合作伙伴选择的理论模型。通过对非对称演化博弈模型的数学分析，认为该模型具有演化稳定策略。在此基础上，构建了多主体模型。仿真结果揭示了企业声誉与企业合作之间信任的中介作用。同时，验证了跨境电子商务公司信任与合作之间信息共享的适度效果。它还为信任和合作行为之间的关系不一致提供了解释。从数学和数据角度来看，本文都试图测试所提出的理论模型，从而丰富了测试理论的方法。
