Abstract: Manufacturers invest R&D production costs in their leading green supply chain, and retailers also make some sales efforts.Considering delayed payment and risk-free interest rate, this paper analyzes the impact of retailer and manufacturer′s fairness concerns behavior on the pricing strategy, sales input and product green degree decision of green supply chain.The results show that the optimal result of decentralized decision-making is always smaller than that of centralized decision-making, and the larger the risk-free interest rate is, the more obvious the gap between them is;taking the solution of Nash negotiation as a fair reference point, the interaction law between the level of fairness concerns, the green efficiency of products and the rate of return on sales will have different effects on the green degree of products, sales efforts and price decision-making;although the fairness concerns behavior always achieves utility fairness by damaging the other party′s earnings, the overall utility of the supply chain will increase to a certain extent compared with the retailer′s fairness concerns behavior.

Key words: green supply chain, trade credit, fairness concerns
