水平竞争中制造商之间信息共享问题研究

文章分析了在一个两层供应链（包括一个零售商和多个制造商）模型中，处于需求不确定环境下，制造商与零售商以及制造商之间关于信息共享的问题。供应链中垂直方向的信息共享为制造商带来双面影响：直接影响和间接影响，而这些制造商之间又是处于竞争关系的。文章将焦点放在了垂直信息共享所带来的间接影响上，通过建立数学模型的方法分析了零售商的均衡行为和制造商的均衡行为，比较制造商在共享信息与不共享信息的情况下所获得的利润，从而揭示了水平竞争中间接影响阻碍了制造商与零售商之间自愿共享信息。

The Research about Information Sharing during Manufacturers in Horizontal Competition

This paper investigates the question about information sharing during manufactures in an uncertainty environment in a two-level supply chain in which there are one retailer and many manufacturers. To manufactures in horizontal competition vertical information sharing has two effects : direct effect and indirect effect. This paper shows the indirect provides disincentives for manufactures to share information with the retailer voluntarily by analyzing the equilibrium behavior of the retailer and manufactures.
