基于演化博弈的双渠道供应链服务合作策略

Dual-channel Supply Chain Services Cooperative Strategy Based on the Evolutionary Game Theory

文章运用演化博弈论的方法,建立了由单一制造商与单一零售商组成的两级供应链中服务合作的博弈模型,分析了影响双方合作的因素。结果表明:当零售商成功地单独提供服务时,只要双方合作的收益大于不合作时的收益,双方就会进行服务合作;零售商单独提供服务失败时,如果双方合作时的收益大于不合作时的收益,则服务合作会出现两种演化稳定状态,此时,合作时的超额收益、零售商合作和制造商服务"搭便车"时的收益增量、合作与非合作时的服务成本、制造商的服务成本分担率等因素会影响双方合作的演化方向。

Using the evolutionary game theory, a game model of service cooperation was established in two-level supply chain composed of single manufacture and single retailer, and the factors affecting the bilateral cooperation were analyzed. The results show that： when the retailer can successfully offer the services alone and the two sides＇ cooperation benefits greater than the benefits of noncooperation, the two sides will conduct cooperation service; when the retailer failed to the service cooperation and the two sides＇ cooperation benefits greater than the benefits of noncooperation, two evolutionary stable state will appear in the cooperation service. In this case, the excess profits of cooperation, income increment of retailer＇s cooperation and manufacture＇s service ＂free-rider＂, cooperative and non-cooperative service costs, the manufacturer＇s service cost sharing rate and other factors will affect the evolutionary of cooperation between the two sides.
