Operation Optimization of Supply Chain Financial System Based on System Dynamics

Supply chain finance solves the problem of financing difficulties for small- and medium-sized enterprises, reduces the risk of financial services of financial institutions, and brings new profit growth points to logistics enterprises. Therefore, supply chain financing has achieved rapid growth in a short period of time in China. This paper aims to study how to analyze and study the collaborative development of supply chain finance based on system dynamics. This paper puts forward the problem of system operation optimization, which is based on system dynamics, then elaborates on the concepts of SD and SCF, and designs and analyzes a case of a supply chain financial system based on system dynamics. The experimental results show that increasing the "bank input" from 0.1 to 2 can bring considerable economic benefits in the long run. As far as the simulation results are concerned, the promotion effect on the supply chain is the most significant. The output value of the supply chain can be increased from 2,963.04 billion yuan to 4,211.73 billion yuan, an increase of 42.14%. The simulation results showed that the financial industry has a significant positive effect on the factor of supply chain support, which provides evidence support for further guiding practice.
