摘　　要：研究在由两个竞争制造商和一个共同零售商组成的二级供应链中,制造商创新投资对零售商信息分享策略的影响.首先构建3种信息分享策略(不分享、部分分享和均分享)下的博弈模型,并对比分析得出零售商最优信息分享策略及不同策略下制造商/供应链利润大小关系;然后,探讨竞争制造商创新投资效率不等和存在横向溢出效应情形下零售商的信息分享策略.研究结果表明:当制造商投资效率相等时,若投资效率较低,则零售商没有动机分享预测信息;若竞争强度较小且投资效率较高,或者竞争强度较大且投资效率适中,则零售商总是倾向于均分享策略;若竞争强度较大且投资效率较高,则零售商选择部分分享策略.当制造商投资效率不等时,零售商更愿意与投资效率较高的制造商分享信息.此外,横向溢出效应更能激励零售商分享信息.This paper investigates how manufacturers’ innovation investment affect retailer’s information sharing strategies in a two-echelon supply chain involving two competing manufacturers and a common retailer. Three information sharing models(i.e., no sharing, partial sharing and full sharing) are established, and the relationships of manufacturers’ or the whole supply chain’s profits under different strategies are obtained by comparative analysis. Then, we extend the basic model to examine how asymmetric investment efficiency and horizontal spillover impact retailer’s information sharing strategies. The results show that when manufacturers’ investment efficiencies are equal, if the investment efficiency is low,the retailer has no incentive to share information;if the competition between two manufacturers is less intense(intense)and the investment efficiency is high(moderate), the retailer always tends to adopt full sharing strategy;if the competition intensity is intense and the investment efficiency is high, the retailer prefers to choose partial sharing strategy. When the investment efficiency is asymmetric, the retailer is more inclined to share information with the manufacturer having higher investment efficiency. In addition, spillover effect always incentivizes the retailer to share information.
