The Evolution Game Analysis on Lacking Credibility of the Network Consumer Market

The research on network consumer market credit has great significance to the prosperity and development of the transaction. To the online shopping system constituted by the network platform operator and E-tailers,we have established credit relationship evolution game model in order to study the credit autonomy among retailers. The change of the relevant parameters has a certain impact on the network strategy,and the evolution and stable state of the system are affected by the initial state of the system. Then introduced the supervision mechanism into model and data simulation analyzed,the results show that the changes of related parameters have certain influence on the system evolution direction. When the supervision and punishment mechanism of the platform operator is introduced appropriately,the betrayal of E-tailers can be effectively reduced,and make the system evolve to a steady Pareto direction.
