Analysis of the Impact of Supply Chain Finance on Working Capital Management in Small and Medium-sized Enterprises

In the current economic environment, small and medium-sized enterprises (SMEs) commonly face dual pressures of working capital constraints and financing difficulties, as traditional financial models often fail to effectively meet their capital allocation needs. As an innovative financing model based on supply chain transactions, supply chain finance integrates information flow, logistics, and capital flow, thereby providing SMEs with new pathways for capital management. This paper focuses on the impact of supply chain finance on the working capital management of SMEs, conducting a systematic analysis from three dimensions: theoretical foundations, impact pathways, and digital transformation. Firstly, it elucidates the theoretical framework of supply chain finance and working capital management, along with their integration mechanisms. Secondly, it analyzes the pathways through which different types of supply chain finance tools affect working capital performance. Finally, it explores how digital technologies drive innovation in supply chain finance and optimize capital management strategies. The research indicates that supply chain finance significantly enhances the turnover efficiency and overall performance of working capital in SMEs through structural integration and procedural embedding, while digital transformation further strengthens the precision and synergy of this process.
