多寡头供应商横向联盟的综合博弈机制研究

近年来,产业寡头垄断供应商为同业竞争者服务的现象日益普遍,寡头供应商之间的合作型竞争关系开始成为供应链研究的新领域.本文应用Bernd价格竞争模型,以3家成本差异的寡头供应商为研究对象,分析了成本差异的垄断供应商之间联盟的建立与博弈机制,阐释了寡头供应商为同业竞争者服务的动机与经济效益.研究表明,供应商成本差异程度与替代系数是决定联盟能否建立的关键因素,实现联盟利益最大化的单位服务费用与联盟供应商的议价能力无关.

On Synthetically Game Mechanism of Horizontal Alliance of Multi-oligopolistic Suppliers

In recently years,it is increasingly common that monopoly suppliers serve their competitors in the industry.The cooperative competition relationship among oligarch suppliers has become a new field of supply chain research.A game model is proposed based on Bertrand Model in this study to analyze establishment and game mechanism of the alliance among monopoly suppliers with cost difference by adopting the three competitive monopoly suppliers as research objects.The study explains the motivation and economic benefits of the supplier serving its competitors.The research shows that cost difference of the supplier and alternative coefficient are factors to determine establishment of the alliance.There is no connection between unit service fee of maximizing the union benefits and bargaining power of supplier.
