摘要: 利用不完全信息博弈研究了两个竞争性品牌供应商通过同一电商网络平台销售产品的需求信息共享问题。结果显示,网络平台共享信息会给自身带来更多的期望利润。当无信息合约时,网络平台愿意将需求信息至少与一个供应商进行共享。特别地,当广告竞争效应较高且收取的佣金比例较小时,网络平台只会对一个供应商共享信息。基于供应商之间的博弈结果,得到了网络平台需求信息的两种定价策略,使得至少有一个供应商会购买信息。当广告竞争效应较高时,网络平台的定价策略使得只有一个供应商会购买信息;而当广告竞争效应较低时,网络平台的定价策略使得两个供应商均会购买信息。最后,通过数值分析进一步说明了论文的结果。

Abstract: By using static game with incomplete information, this paper explores information sharing strategies of an Online platform with two competitive brand suppliers. The results show that demand information sharing benefits both the platform and suppliers. Without information contracts, the online platform is willing to share demand information with at least one supplier. Especially, when the consumer's sensitivity to advertising is larger and the commission fee charged by the online platform is small, the online platform will shares information with only one supplier. Based on the game outcomes between the suppliers, two pricing strategies for information are proposed under which at least one supplier purchases information. If the consumers are less (more) sensitive to advertising competition, pricing strategy of the online platform induces that both suppliers (only one supplier) purchase(s) information. Numerical studies further illustrate the findings in this paper.
