利用演化博弈的理论, 探讨了供应网络中处于不同位置的核心企业和非核心企业两个群体间的成员其投入合作的策略根据收益变化而改变的演化过程; 建立了复制动态方程并求得平衡点解, 据此通过复制动态的相位图直观反映了博弈的演化稳定策略; 并通过Netlogo软件对企业行为选择与收益的关系进行了仿真, 其行为选择的演化结果与相位图展示结果具有一致性。研究结论表明, 收益获得及变化是企业合作行为改变以及合作策略选择的重要依据, 企业间演化稳定策略不仅仅局限于参与合作与放弃合作, 长时间观望也是企业可能的策略选择; 最后针对如何提高供应网络企业间合作的稳定性提出了对策建议。

Using the evolutionary game theory, this paper discussed the cooperative strategy evolution process with profit changes between the core enterprises and non-core enterprises in supply network. It established the replicated dynamic equations and obtained equilibrium solutions, according by the phase diagram of replicate dynamic reflected the stable strategies of evolutionary game. It carried out the simulation on the relationship between enterprises' behavior and the profits using Netlogo software, proved the results had consistency with the phase diagram showing. The research results indicate that the profit obtained and changes are the most important basis for enterprises to change behavior and select strategy, the stable strategies of evolutionary game for enterprises not only participate and cooperate, give up cooperation or watching for long time are also the possible strategy choice. Finally it put forward suggestions for how to improve the stability of enterprises cooperation in supply network.
