Estimation Of Bank's Optimum Pledge Rate Based On Supply Chain Finance Confirmed Warehouse Financing Model

Compared with the traditional credit model,the supply chain financial business is a great innovation.It breaks the traditional static risk assessment method which is often used by traditional credit,which is based solely on the financial statements and operation scale of enterprises,but dynamically evaluates the credit risk of financial institutions from the perspective of the overall supply chain.Confirmed warehouse financing is one of the typical supply chain financing.It is mainly participated by upstream suppliers(core enterprises),retailers(borrowing enterprises),third-party logistics enterprises(warehouse receipt supervisors),financial institutions(fund providers)and so on.This model can not only reduce the default rate of the whole supply chain by virtue of the good reputation of core enterprises,but also help SMEs to achieve financing projects.Standards can also share the credit risk of banks to a certain extent.Through quantitative analysis,this paper focuses on exploring and analyzing the optimal pledge rate of banks under the conditions of overall supply chain default rate and downside risk avoidance constraint under the supply chain financial confirming warehouse model and when market demand is uncertain,and further considering the game among the participants(banks,core enterprises,borrowing enterprises)in the supply chain.Equilibrium decision-making,sensitivity analysis of model parameters through numerical simulation,further analysis of simulation results,and to verify the conclusions of this paper.The results show that bank's pledge rate,expected profit are proportional to supplier's repurchase rate and credit contribution,and inversely proportional to retailer's order quantity.The smaller the risk aversion degree of bank,the bigger the pledge rate,the larger the retailer's optimal order quantity and the bigger the supplier's expected profit.When the bank's risk preference reaches a certain range,its risk attitude no longer affects other main body of supply chain.Decision-making and expected profits.Through the above research and analysis,this paper further enriches the theoretical research of confirming warehouse financing,and provides decision-making ideas and practical guidance for all participants in the supply chain.
