Abstract:  The rise of the closed-loop supply chain mode perfects the ecological cycle of product life cycle, and its commercial value and environmental advantages are being explored and verified in many ways Recycling enterprises are the main participants in the closed-loop supply chain, but compared to the traditional small and medium-sized enterprises, they confront more severe financing environment, which is a major obstacle to the development of the closed-loop supply chain Based on the research of domestic and foreign scholars, a closed-loop supply chain financial framework is constructed, and operational decision-making analysis method is used to discuss the financing choice of recycling enterprises under different project success probability from the perspective of financing income-cost Comparative analysis of the closed-loop supply chain finance and traditional financing methods is made to find the financing optimization strategy The results show that the closed-loop supply chain financing mode greatly expands the financing possibility boundary, effectively reduces the risk brought by information asymmetry, and can achieve greater profits compared with traditional financing modes
