Optimal Deeision Of Diferent Channels With Considering Trade Credit Under The Concern Of Fairness

With the development of the economy and the Internet,online direct sales channels have great attraction for the traditional suppliers with only one sales channel.And with the opening of online direct marketing channels,the relationship between retailer and supplier become different,there is no longer just partner relationship between them,they are especially the competitors.it easy to create fairness concerns problem,and fairness concerns not only arises from the dual-channel in the supply chain,in single channel,the suppliers and retailers also will focus on fairness.With the development of the logistics industry,more and more financing products are produced in the logistics field.As a widely used financing product with practical significance,trade credit is used more and more frequently in the supply chain.Research shows that trade credit can improve the speed of capital flow in the supply chain,reduce transaction costs and create more supply chain surplus.Trade credit is an important short-term financing tool in supply chain.Based on the above information,this paper takes trade credit as a financing tool for supply chain members.The retailer uses trade credit as payments to the supplier,and the supplier decides the term of commercial credit to the retailer.Considering a supply chain system with one supplier and one retailer,there is a Stackelberg game between the retailer and the supplier,in which the supplier is the leader.In this paper,a Stackelberg game model with commercial credit decision is established for single-channel supply chain and dual-channel supply chain with different fairness concerns.The comparison between the optimal decisions shows the influence of different fairness concerns status on the decisions of the supplier and the retailer.The results are as following.First,the channel change has a direct impact on the decision-making of supply chain members,but the direction of the decision remains unchanged,that is,the channel change will affect the decision-making of supply chain members,but will not change the impact of fairness concerns on the decision-making.Second,no matter in single channel and dual-channel,when only one party has the fairness concerns,the retailer optimal decision of the price increases with the supplier of fair degree increases,its own fairness concerns will not affect the price decision,but when both sides have fairness concerns,the retailer's decision is not only increases with the supplier's fairness concerns,also with its own fair concernsincreases.Third,regardless of the state of fairness concern,the optimal decision of the commercial credit term provided by the supplier decreases with the increase of the fairness concern of the supplier and increases with the retailer's fairness concerns increases.Fourth,through the decision-making results,we also found that in the dual-channel,the supplier's direct online price is not affected by the supply chain members' state of fairness concern.Through numerical analysis,the conclusion is demonstrated,and the impact of equity concerns on decision making and benefits of supply chain members can be seen more intuitively.In the end,I summarized the research and the future development direction of this paper.
