第三方电子商务平台与加盟商家联盟稳定性的演化博弈分析

针对电商平台的加盟商家的“跳单”现象,建立了第三方电子商务平台与加盟商家的博弈模型,利用演化博弈的方法分析了第三方电子商务平台的监管和加盟商家违约跳单的策略选择演化过程,给出了不同情形下他们的演化稳定均衡策略。若双方的策略不符合演化稳定均衡策略,则会影响他们形成的联盟的稳定性。此外,本文根据实际情况做了相应的参数设置和变量假设,并通过理论分析和情景仿真得到了加盟商家跳单的金额、平台因加强监管且加盟商家没有跳单而获得的额外收益等参数变化时对演化稳定均衡策略的影响。

Alliance Stability between Third-party E-commerce Platformand Cooperative Merchant Based on Evolutionary Games

In view of“jump-dealing”phenomenon in cooperative merchant,this paper establishes the game model between third-party e-commerce platform and cooperative merchant,and analyses the evolutionary process of supervision from third-party e-commerce platform and“Jump-dealing”of cooperative merchant based on evolutionary game theory-And the evolutionary stable strategies(ESS)for this model under different circumstances are given.The stability of alliance will be affected if their strategies do not conform to the evolutionary stable strategies(ESS).In addition,parameter settings and variable hypothesis are also made according to actual situations,and how the different parameters,for example,the amount of money merchant jumping and extra revenue gained by the platform by strengthening supervision,can influence the evolutionary stable equilibrium strategy is analyzed based on theoretical analysis and scenario simulation.
