为了解决供应商隐藏成本信息、销售商隐藏努力行动所引起的逆向选择和道德风险问题，文章基于委托代理理论，引入虚拟第三方为协调主体，分别站在供应商和销售商的角度，通过设计合适的契约激励销售商努力工作和供应商“说真话”。研究结果表明，当供应链中只有道德风险存在时，可以通过如（16）式的契约（其中契约参数λ∈[0，1]）实现供应链的完美协调；但是，当供应链中不仅仅存在道德风险还存在逆向选择时，该契约参数不再是区间[0，1]上任意的值，而是与供应链交易量q及供应商的生产成本c相关的定值（满足（29）式），此时的供应链才能实现协调；在该契约下，为获得更多的利益，供应商更有动机降低自身生产成本，销售商也更有积极性提高努力水平，从而实现“双赢”。最后，通过数值算例对模型进行了应用分析。

To solve the adverse selection and moral hazard when the supplier hides its information about produc -tion cost, and the retailer hides its action about sales effort , a virtual-third party is introduced as a coordination body to implement double incentives on the basis of principal agent theory .And respectively from the perspective of supplier and retailer, a contract is designed to incent the supplier to tell the truth and the retailer to work hard.The results show that if there is only moral hazard , the perfect coordination of the supply chain could be realized by the contract as expression (16).However, if there is not only moral hazard but also adverse selec-tion, the coordination of the supply chain could be achieved only when the contract parameter has a constant val -ue.And this value is related to the trading volumeq and the supplier ’s production costc(as expression(29)).Moreover, the supplier is encouraged to cut its production cost and the retailer is incented to improve the effort level, so the “win-win” result is reached.Finally, a numerical example is given to illustrate application of this model.
