Study on coordination mechanism of closed-loop supply chain of emergency products from perspective of differential carbon tax
To improve the resource utilization efficiency of emergency products and strengthen the coordinated green develop-ment of emergency system,a game model of the closed-loop supply chain of emergency products was constructed,with the manufacturers in a leading position and the retailers in a subordinate position.From the perspective of differential carbon tax,the equilibrium decisions of the closed-loop supply chain of emergency products under centralized decision-making and decen-tralized decision-making were compared and analyzed,then the conditions for achieving supply chain coordination using the"bargaining"model were derived,and a case analysis was conducted.The results show that the differential carbon tax policy can increase the market share of remanufactured emergency products,thus promote the efficient recycling development of re-sources,and the"bargaining"model can achieve the effective coordination of the closed-loop supply chain.The research re-sults provide a theoretical reference for responding to emergencies.
