中文摘要：

在节点企业地位相当的二级供应链中,销售商隐藏努力行动、供应商隐藏成本信息,从而导致供应链效率低下。为此,运用委托代理理论,引入虚拟第三方为协调主体,从供应链整体利益最大化出发,对供应链进行集中控制、利润分配,对供应商和销售商实施双向激励。结果表明,与供应商主导供应链时的情形相比,当销售利润共享比例α＊和成本共担比例β＊满足更为苛刻的关系时,供应链才能实现协调。但是,此时的虚拟第三方承认了供应商的信息租金,其决策的角度是供应链期望利润的α＊倍。最后,通过一个算例对研究结果进行了说明。

英文摘要：

In a two-stage supply chain,the supplier and retailer are equal in market power.The supplier hides its information about production cost and the retailer hides its action about sales effort,which results in low efficiency of supply chain operation.To cope with this problem,a virtual-third party is introduced to represent the whole interests of the supply chain as coordination main body.The virtual-third party realizes centralized control,profits distribution and double incentives.Main results reveal that compared to the situation in the retailer-led supply chain,only when the revenue sharing ratio and cost sharing proportion satisfies the more stringent constraint,the supply chain coordination could be achieved.However,because the virtual third-party admits the supplier＇s information rent,it made decision on how many times of the whole supply chain＇s expected profit.Finally,the study results are illustrated by a numerical example.
