ABSTRACT

We consider a two-echelon supply chain with a supplier and a retailer, both with capital constraints. The capital-constrained retailer will first apply for loans from the bank, and then apply for trade credit from the supplier. Compared with the single trade credit financing mode, what are the similarities and differences in the contagion and evolution of the associated credit risk in the supply chain when the retailer adopts both trade credit and bank credit (dual-channel financing) mode. Based on Stackelberg game, this paper clarifies the contagion mechanism of the associated credit risk in the supply chain and discusses the influence of financing structure, financing channel and financing costs on the contagion effect of the associated credit risk in the supply chain under a dual-channel financing mode. Combined with the simulation analysis, it is found that compared with the single trade credit financing mode, the contagion effect is weaker under the dual-channel financing mode. The financing structure will significantly affect the contagion effect, which will increase with an increase of the proportion of trade credit financing. Both bank credit and trade credit financing costs can positively affect the contagion effect. Our research can enrich the existing credit risk management literature and provide decision support for the selection of financing methods and risk control of supply chain enterprises.
