不同力量对比供应链中制造商竞争策略研究

A Research on the Manufacturers' Competition Strategies for the Supply Chain with Different Power Structure

笔者采用纳什博弈和斯坦伯格博弈结构,分别表述力量对等和力量不对等供应链中零售商和制造商的决策过程,分4种情形探讨了2个制造商在不同竞争策略下,供应链中成员的最优决策。从制造商的角度出发,着重分析在不同力量结构的供应链中制造商的竞争策略选择。研究结果表明:制造商竞争策略的选择依赖于产品的差异性及生产成本的大小。

With the game theory , this paer analyzes the manufacturers＇ competition strategies in the two different power structures with equal power and the retailer dominant power： price competition strategy and quantity competition strategy. Firstly , the Nash model and the Stackelberg model are employed to describe the supply chain of equal power and the retailer dominant power, separately, on which, the optimal decisions of the supply chain＇ s players are obtained with the different competition strategies of the manufacturers. Second-ly, from the manufacturers＇ point, the choice of the competition strategies are discussed in the supply chain with different power struc-ture. The results show that the choice depends on the products differentiation and the production cost.
