Coordination Research Of Sales Rebate Contract Under Different Supply Chain Financing Modes

With the further development of social specialization and economic globalization,competition between enterprises gradually transfers into the competition betweensupply chains. The effective integration of supply chain logistics, information flow,and fund flow is the key point to improve the competitiveness. At present, enterprisesand research institutions pay more attention to the cash flow of supply chainespecially capital constraint problem. Powerful core enterprise of supply chain oftendelays the payment of suppliers accounts and requests its downstream to paypurchasing cash in advance, and so on, which can easily result in capital constraint ofsmall and medium-sized enterprises upstream or downstream, influence their normaloperation, and also cause low efficiency of the entire supply chain. In order to solvesuch problems, supply chain finance joined by the banks arises rightly, which bringthe gospel to the small and medium-sized enterprise as the effective solution.Supply chain contract as the operation optimization method of supply chaincoordination, has been widely used. Supply chain contract coordination underdifferent supply chain financing modes also gets more and more scholars’ attention.This paper studies three kinds of supply chain financing modes-traditional loanfinance, confirmer wharf finance, delayed payment, uses Stackelberg game to buildthe optimal parameters setting model of sales rebate contract, analyses whether supplychain coordination is achieved, and compares supply chain overall income and eachparty’s earning of the three modes. Based on our assumptions of research, We findthat, sales rebate contract can motivate retailers to increase their order, profit ofsupply chain members can also be improved; Comparing traditional loan withconfirmer wharf finance, the latter can improve the optimal order quantity, and whenretailer receive retained profit, the whole supply chain profit rises, and manufacturer’sprofit also increases, so the supply chain realize Pareto optimization, the sameconclusion can be achieved by the comparison of traditional loan with delay payment;retailer’s optimal order quantity is always smaller than the system’s optimal one incentralized decision under the three modes, so sales rebate contract can’t realize theperfect coordination of supply chain. At last, an actual case is computed to verifythese.
