Abstract: In order to analyze supply chain structure, cost model of firms in market entry game was developed by borrowing Cournot competitive model and Newsvendor problem model, the feasible and equilibrium structures of two-tier supply chain were analyzed and solved in theory. For those multi-tier supply chain or enterprise with more complicated cost structure, evolutionary game theory was introduced, and enterprise acting as player of game in supply chain adopted self-adaptive learning mechanism. In application of the framework of evolutionary game model, the equilibrium structure of supply chain was solved through a simulation, and the outcome was consistent with the theoretical studies. Therefore, it provided theoretical evidence and feasible method for analysis of market entry game in complicated supply chain via evolutionary game.

Key words: supply chain structure, market entry game, evolutionary game
