基于进化博弈的供应链市场进入博弈分析

为分析供应链的结构，在借鉴古诺竞争模型与报童问题模型的基础上，建立了市场无法出清条件下供应链的市场进入博弈模型，从理论上分析并求解了两级供应链的可行结构和均衡结构。对于多级供应链或者企业成本结构更加复杂的问题，引入了基于进化博弈的分析模型，模型中的企业作为博弈参与人采用适应性学习机制，利用仿真试验，分析供应链市场进入博弈问题，验证了实验与理论结果的一致性，从而为分析复杂的供应链结构提供了理论依据和可行方法。

Market entry game in supply chain based on evolutionary game

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.
