Research On Decision-making Of Closed-loop Supply Chain Under Fairness-Concern Perspective Of Weak Enterprises

The implementation of closed-loop supply chain management not only can save resources,but also can improve the efficiency of enterprises in the rapidly changing market to enhance competitiveness,so it has important practical significance to do research of closed-loop supply chain.Based on the research of predecessors,this paper puts forward the closed-loop supply chain led by retailer and manufacturer respectively,introducing the fairness-concern behavior and discussing the impact of carbon emission regulation on retailer-led closed-loop supply chain in combination with the background of low-carbon environmental protection.In this paper,we use game theory to study the effects of fairness-concern and carbon emissions regulation on the closed-loop supply chain decision-making,mainly from the following aspects of research and exploration:(1)In the closed-loop supply chain led by the manufacturer,established retailer's fairness-concern and collector's fairness-concern decision-making models,discussed the fairness-concern from two aspects of jealousy and empathy behavior.The study shows that jealousy fairness-concern can improve the bargaining power of decision makers in the closed-loop supply chain;the empathy fairness concern is a kind of altruistic behavior.The retail price increases with the increase of jealousy coefficient,and the collection rate increases with the increase of sympathy coefficient.(2)In the closed-loop supply chain led by the retailer,established manufacturer and recycler fairness-concern decision-making model,discussed the influence from two aspects of jealousy and empathy behavior.The study shows that the collector fairness-concern has no effect on the retailer leading closed-loop supply chain.The retailer's unit product profit is reduction function of the manufacturer's jealousy coefficient and increase with the increase of psychological coefficient.(3)Introducing carbon regulation into retailer-led closed-loop supply chain,the study shows that buy-back price is not affected by carbon emission regulation.Collection rate,retail price,unit product profit and whole-sale price are the increasing function of emission reduction coefficient.The retailer and collector can benefit from the manufacturer's emission reduction measures,the profit is higher than the non-carbon emission regulation.Because of the reduction of the cost of investment,the manufacturer's profit is lower than the carbon emissions regulation.
