Government incentive mechanism of closed-loop supply chain based on information asymmetry
Aimed at the closed-loop supply chain (CLSC) composed of the manufacturer, the retailer and consumers in the waste products market, this paper studies how the government handles the adverse selection problem on the hidden recovery costs of the retailer and deals with the moral hazard problem on the level of retailer's hidden efforts. A government incentive regulation aiming at maximizing social welfare has been established based on the incentive theory in this paper. A list of contracts with transfer payments is presented to reveal the retailer's collection efficiency and motivate the retailer to make the optimal investment. Further, the impact of related factors on the recovery cost and social welfare level according to the numerical simulation are verified. The results show that under the government regulation, only by reporting the true recovery technology type information to the government can the retailer maximizes the profit. In addition, the retailer with high recovery efficiency can obtain both retained profit and additional information rent. Finally, as the retailer makes efforts to improve the recovery level, it also increases investment cost, which affects the enthusiasm of enhancing the retailer's recovery efficiency. Therefore, the government should not blindly pursue the improvement of recycling efficiency regardless of the cost, but should pay more attention to the control of recycling equipment and technology cost.The results facilitate scientific policy development, and provide a reference for promoting closed-loop supply chain operations.
