摘　　要：本文基于演化博弈理论,针对交易双方的有限理性,建立了一个引入博弈参与人学习调整的农产品买卖交易模型,分析了个体策略选择机制在模型中的动态演化过程,得出了博弈参与人通过不断的学习调整,最终形成"强-弱"或"弱-强"要价策略组合的稳定均衡结果的结论。在此基础上,进一步探讨了买卖双方偏离独立的个人价值差异区间中心点的程度对演化稳定均衡解的影响。Based on the evolutionary game theory,and according to the bounded rationality of transactions between two sides,this paper establishes the evolutionary game model of agricultural product trade in which introduces learning to adjustment of participants are introduced,and analyzes the dynamic evolutionary procedure of system. And it analyzes the stable equilibrium of strategy profiles that is ＇ strong-weak＇ or ＇ weak- strong＇ through continual learning adjustment of the participants. Finally,it further explores key factors affecting the evolutionary stable equilibrium of system,which is the deviation degree of differences of personal values between buyers and sellers.
