Analysis on credit construction of the electronic commerce platform by evolutionary game

Through establishing the dynamic evolutionary game model, this paper analyzes the stable evolutionary equilibrium of China's e-commerce platform service providers and shop operators in the credit construction investment and cooperation, and analyzes the shop operators of weak ability on credit construction investment cooperation which are supported by the platform service providers. Studies have shown that varieties of evolutionary stable equilibrium emerge one by one, (no investment, no investment), (investment, no investment), (no investment, investment) and (investment, investment) in the process of platform and shop's continuous development. What's more, under the situation of (investment, no investment), platform's support has a positive impact on the participation in cooperation of credit construction for the weaker shops.
