Research on Coordination Mechanism Design of Closed-Loop Supply Chain for New Energy Vehicle Power Batteries

Taking the power battery closed-loop supply chain system composed of new energy vehicle manufacturers, automobile retailers and echelon utilization enterprises as the research background, this paper constructs a centralized decision-making model and a decentralized decision-making model based on Stackelberg game led by new energy vehicle manufacturers, and investigates the design of coordination mechanisms for the power battery closed-loop supply chain. The results reveal that the decentralized decision-making model fails to coordinate the power battery closed-loop supply chain due to the existence of double marginalization effect. By contrast, the proposed coordination mechanism combining recycling service cost-sharing and two-part tariff can not only effectively coordinate the supply chain, but also achieve Pareto improvement in the profits of all members within the closed-loop supply chain.
