In the e-commerce supply chain, many risk-averse suppliers face the dilemma of capital constraints. Bank financing helps to alleviate these financing difficulties, and blockchain trust mechanisms can optimize bank financing strategies. To address the issue of capital constraints for suppliers, based on the two operating modes of Consignment and Direct Selling in the e-commerce supply chain, using the Stackelberg game, considering the company's risk-averse behavior and consumers' green preferences, a game model is constructed to explore the impact of factors such as blockchain, risk aversion, product greenness, information verification efforts, and guarantee interest rates on bank financing strategies. Studies have shown that when blockchain technology is adopted within a certain threshold range, suppliers adopting the Consignment method can achieve higher financing returns than the Direct Selling method. Compared to the Direct Selling method, under the Consignment method, the blockchain trust mechanism can better function to improve the supplier's financing efficiency, and managers can choose a more optimal sales model based on actual circumstances. The supplier's financing efficiency also decreases with an increase in the risk aversion coefficient, and under the scenario of using blockchain, the effect of risk aversion on suppliers is greater. However, blockchain trust increases with the increase in the risk aversion coefficient, and managers can optimize internal risk management mechanisms and take measures to reduce the negative effects of excessive risk aversion. Product greenness will increase the selling price of the e-commerce supply chain under the Consignment method, and enhancing product greenness helps to improve corporate cash flow. However, under the Direct Selling method, the impact on price is minimal, and the impact on financing strategies will differ. Information verification efforts will lead to an increase in product greenness and the green preference coefficient, and the improvement in information transparency makes e-commerce more willing to provide guarantees for suppliers. Although the guaranteed interest rate will increase financing costs, it will make banks more willing to provide financing for suppliers with capital constraints, and in practice, managers should comprehensively consider the balance between guaranteed interest rates and financing returns. This study aims to provide decision-making references for managers.
