在供应链逆向选择问题中,代理人只获得基本的保留收益或者可怜的信息租金,导致对代理人的激励不足,缺乏效率。为了解决这个问题,文章在一个供应商和一个销售商组成的二级供应链中,引入不占有利润的虚拟第三方进行集中控制、利润分配、信息甄别。最后制定了逆向选择的最优契约,并且证明了在虚拟第三方控制下,各参与者均可获得正的租金,应用数值分析说明供应链的整体收益有所增加。
On common adverse selection of supply chain,the agent can only gain basic retained earnings or poor information rents,so the agent can not be incentive enough.The paper analyzes the supply chain,consisting of only one supplier and one retailer,with the control of virtual third-party.The virtual plays the role of centralized control,represents the interests of the supply chain,designs and implements the incentive mechanism to adverse selection.At last,we establish the first best incentive contract,and all partners can gain some rents.
