摘　　要：　从博弈参与人的有限理性出发,探讨了合作竞争博弈中复杂性存在的根源,在此基础上应用演化博弈论的方法探讨了合作竞争博弈的演化模型,这是一个复制动态模型,因而我们可以借用生物学中的"复制动态"机制来模拟参与人的学习与调整机制,用"进化稳定策略"来描述合作竞争博弈的长期演化趋势,最后分析了一个水平差异化产品的合作竞争博弈的演化均衡与稳定性,及其演化过程中所表现出来的复杂性.From the bounded rationality of player in cooperation games, the sources of complexity are discussed. Based on this idea, the evolution model of co-petition games is studied, this is a replicator dynamics model, so we can describe the learning and adjustment of players by using the mechanism of replicator dynamics, and describe the evolution of co-petition in the long run by using the evolution stable strategy. At the end of this paper, the evolutionary equilibrium and stability of co-petition in a horizontal differential market are explored, the complexity in evolution is studied.
