摘　　要：供应链中的物流、资金流都依赖于信息流,然而供应链中的信息具有不对称性,供应链下游企业掌握的需求信息,恰恰可以帮助供应链上游企业进行库存决策,从而降低成本、提高效益。构建一个供应商和多个零售商组成的二级供应链模型,以库存成本作为价值尺度量化信息分享价值。零售商处于不同的市场需求环境中,因此需求波动也各不相同。创新性地加入零售商面对的市场需求波动的相关性这个变量,分析零售商和供应商分别在需求信息不分享和分享时的最优库存决策以及库存成本,并进行算例研究。算例研究中讨论四个变量对信息分享价值的影响,它们是:市场需求波动程度、需求在时间上的相关性、零售商需求间的相关性、进行信息分享的零售商数量。得出的一系列分析结论对供应链上需要进行信息分享的厂商具有一定的启示。The material flow and the fund flow depend heavily on the information flow in the supply chain where information is asymmetry.The specific information on demand acquired by downstream enterprises may help upstream enterprises in inventory decision-making so as to reduce the cost.This paper constructs a two-level supply chain model to quantify the value of information sharing by measuring stock costs.The variances of retailers＇ demands are different in different markets.In this paper,the variable denoting relevance of market demands in which retailers operate is added to the model,analyzing the impact of information sharing to stock cost under different variable choices,and carrying the numerical study.In the numerical study,we discuss the impact of four variables on the value of information sharing： demand fluctuation,demand correlation in time,demand correlation among retailers,and the amount of information sharing retailers.This paper has drawn a series of conclusions,which are considerably useful to enterprises which want to implement information sharing in the supply chain.
