摘要:Because small and medium-sized enterprises have problems such as high operating risks and a small proportion of real estate, they are facing difficulties in financing. Commercial bank supply chain finance provides an effective way for small and medium-sized enterprises to finance, and to a certain extent solves the problem of corporate financing difficulties. However, some of its existing problems have restricted its innovation and development. The “blockchain + supply chain finance” dual-chain model has effectively overcome the shortcomings of the banking industry in developing supply chain financial services. This article takes Zheshang Bank’s accounts receivable chain platform as the research object, explores the advantages and related risks brought by the application of blockchain technology, and puts forward the optimization suggestions of Zheshang Bank’s accounts receivable chain in supply chain finance.
