从全球化市场的角度考察了产业竞争结构,构建了两层的上游供应链竞争结构。运用博弈论的基本思想,首次建立了基于两种竞争策略的制造商效用模型,考察了制造商市场竞争中所存在的非对称信息和对称信息两种情况,对制造商和供应商的决策进行了研究。结果表明:制造商在非对称信息和对称信息两种情况下均存在着三种纳什均衡策略参与市场竞争,而供应商存在着选择单位成本的机会主义倾向。本文的研究成果对供应链上位各成员的决策均有重要的指导意义。
In this paper,the structure of industrial competition is studied in global market's view,and the structure of upper supply chain is constructed in Two-echelon.Applying the basic idea of game theory,utility function of manufacturer is established based on two kinds of competition strategies,and possible competition strategies of manufacturers and supplier are analyzed under asymmetric and symmetric conditions.The results indicate:manufacturers would have three Nash equilibrium strategies under the two conditions and supplier would be possible to choose cost per unit in terms of opportunism.This study will provide a valuable guidance to the decision of supply chain.
