Inventory Financing Decision Based On Double Stackelberg Game

More than 50 million small and medium enterprises in China,accounting for95% of the total number of enterprises.SMEs contribute to more than 60% new wealth,for total tax,SMEs ' contribution exceeds 50%,provides more than 80% or more jobs.However,conditions for SMEs are not as optimistic,more than 80% of SMEs are faced with financing difficulties.SMEs are small,weak,Banks typically defined it as high risk,high cost,so in traditional,SMEs are hard to obtain loans.Less working capital and large of inventory,inventory as collateral for financing has become an important financing for SMEs.With the constant exploration,supply chain finance came into being.This paper focuses on one of the supply chain finance-inventory financing.Inventory financing can help to realize "three-win".SMEs do not have sufficient funds to order goods from the manufacturer,small and medium enterprises taking the inventory as a pledge of stock to the Bank.A core enterprise manufacturer to retailers helps to provide credit guarantees and signs partial credit guarantee contracts with the banks: agreed if in the final SMEs can't repay the loan,the core manufacturer accordance with the contract pays part of principal and interest and of loans to banks.SMEs ' access to loans from banks,can help to order goods from the manufacturer.The demand of inventories are stochastic fluctuates discussed in this paper,based on the assumptions and parameters symbol to calculate the profits of banks,manufacturers,retail.All three seek to maximize their profits.Retailers decide order quantity,manufacturer decides wholesale prices,Bank decides mortgage rate decisions to achieve their profit goals.Because of the strength and status,in the decision-making process,formed the leaders and the followers.Available double Stackelberg game models can describe the decision-making process of the three.In the game between the banks and enterprises,the Bank acts as a leader,in the core game between enterprises and SMEs,core businesses act as a leader.According to the Stackelberg game backward induction,in turn solve retailers the optimal order quantity decision,manufacturer of the best wholesale pricing decisions,the Bank's best mortgage rate decision.Analysis of influence factors of Bank mortgage rates.Banks and manufacturers weigh to decide the Coefficient of partial credit guarantees of credit guarantee contracts According to the decision between banks and manufacturers,we can calculate the optimal coefficient of credit guarantees.Finally,assign a value to the parameter,and use MATLAB programming,to simulate the numerical results.
