Existing C2C´s credit evaluation system is an important tool to help buyers and sellers who make transactions online to regulate their credit. Since sellers´credit, which imposes profound reference for buyers to decide whether to purchase or not, to safeguard their own interests, some sellers use a variety of ways to undermine the credit evaluation system after they received a bad evaluation from the buyer. By applying evolutionary game theory, this paper simulates the online trading mutual credit evaluation process. An evolutionary game model between buyers and sellers is built to study and analyze the evolving process of participant´s behavior and key factors affecting evolutionary stability. It promotes government and the Third-party platform to make effective decisions maintaining the authenticity of the credit evaluation system.
