An Analysis Of Decision Of Supply Chain Finance System Under A Partial Guarantee Contract

SMEs are an important part of the national economy and have the role of promoting the development of the national economy.However,the difficulty of financing severely limits the development of SMEs and reduces the effectiveness of the supply chain system.The innovation of supply chain finance,to a certain extent,can ease the difficulties of SMEs financing.In the supply chain financing model,there emerges a model that the core company provides a credit guarantee for downstream retailers.But the profit of the core company is not clear to the SMEs with the supply chain finance.At the same time,the core company needs to provide certain credit guarantees for SMEs.The enthusiasm of the core company is relatively low in supply chain finance.Based on this,this paper studies the decision-making of the participants in the supply chain financial system and the supply chain system under a partial guarantee contract.In this study,we first design a supply chain finance system comprising a retailer,a manufacturer,and a commercial bank,and formulate a bilevel Stackelberg game model in which the bank acts as a leader,analyzing the decision-making of the participants in the supply chain financial system.The Stackelberg game model is used to give the optimal decision and the maximum profit of participants in the decentralized decision-making situation.At the same time,the profit of the supply chain finance system in the centralized decision-making are calculated.Through calculation,it is proved that under the partial guarantee contract,the retailer has an optimal ordering strategy,and the core company has an optimal wholesale price.T hen,study the changes of the decision-making and profit of various participants by introducing a retailer with the core company's guarantee.By introducing a retailer with the core company's guarantee,it is found that the overall benefit of the supply chain system can increase under the decentralized system.At the same time,the benefit of the retailer and the manufacturer increase too.Finally,combined with the practical application of supply chain finance,the model is extended to the supply chain Stackelberg game model with multiple competitive retailers.A general and universal decision results are summarized.By conducting numerical analysis on the important parameters of the model,we can find that the retailer's loan coefficient and credit guarantee coefficient can narrow the gap between the optimal profit of the supply chain financial system under the centralized decision-making and the total optimal profit of the supply chain financial system in the decentralized.The purpose of this paper is to study the impact of the partial credit guarantee contract of the core enterprise on the decision-making and profit of various participants in supply chain finance and the whole supply chain.At the same time,combined with the results of the model,the paper puts forward corresponding suggestions for developing the supply chain finance business of banks and core enterprises.
