买方势力下零供关系的演化分析

Analysis of Evolution of Retailer-supplier Relationship under Buyer Dominance

建立了买方势力下供应商与零售商合作的博弈模型,在分析占主导地位的零售商与供应商的不同策略时各自成本和收益的基础上,运用混合战略NASH均衡及演化博弈理论研究了双方的博弈关系,模型分析结果表明:零售商对机会主义供应商的监督成本、对提供劣质产品供应商的惩罚力度,都将影响博弈结果;供应商与零售商两个群体,在三类情况下都存在演化稳定策略,而且一定情况下他们的博弈过程表现为一种周期性行为。

In this paper, we built the model to describe the game in the cooperation between the supplier and retailer under the dominance of the buyer, then on the basis of an analysis of the respective cost and benefit of the dominant retailer and supplier under different strategies, used the Nash Equilibrium and the evolutionary game theory to study the game relationship of the two, and reached and elaborated on the findings.
