Research on the Evolution Path of Supply Chain Financing for Small and Medium-sized Enterprises

Information asymmetry is the main reason why it is difficult and expensive for small and medium-sized enterprises to obtain financing. This paper uses the system dynamics method to construct an evolution model of the supply chain financing system of small and medium-sized enterprises, simulates the dynamic changes of the financing amount of the supply chain financing system of small and medium-sized enterprises, and explores the relationship between various influencing factors and their effects on the financing amount. The research shows that the supply chain financing of SMEs is a complex and dynamic system, and the overall financing amount has a significant cumulative effect, and is more sensitive to the solvency of SMEs, the relationship between core enterprises and financial institutions, government support, and the degree of supply chain information sharing. In order to alleviate the financing difficulties of small and medium-sized enterprises, the government should increase support for the supply chain financing of small and medium-sized enterprises, banks and other financial institutions should strengthen the supply chain financing service capabilities of small and medium-sized enterprises, small and medium-sized enterprises should pay attention to the improvement and upgrading of internal management, and the main body of the supply chain should strengthen cooperation and communication.
