Evolutionary Game Research on E-commerce Credit Behavior Based on Platform Supervision

With the popularization of the Internet and the development of information technology, e-commerce develops rapidly with low cost, high efficiency, and cross-region. Online shopping has become more and more important in daily life. However, due to the asymmetry of information between sellers and consumers, the discredit of e-commerce becomes serious. As the medium of e-commerce transaction mode, the regulation of the platform cannot be ignored. Based on the evolutionary game theory, this paper constructs an evolutionary game model with e-commerce platform and seller as the behavior subjects, establishes the replication dynamic equation of the two parties, and analyzes evolution path and the influence of relevant parameters on the behaviors of sellers and e-commerce platform. The study provides decision support for reducing regulatory costs, standardizing honest operation, and promoting the steady development of e-commerce economy.
