Combined with related literature, this paper argues that the application of blockchain technology to supply chain carbon emissions and financial regulation can play a role in reducing the credit risk of corporate supply chain finance. To verify the inference, the initial model of supply chain financial credit risk assessment is constructed using factor analysis and logistic regression analysis. The study selects 105 sample enterprises that utilize blockchain technology in supply chain carbon emissions and financial regulation to construct a final model for supply chain financial credit risk assessment as P=1-11+e5.366-5.594F1+1.114F2+3.368F4

. The risk-taking capacity of Enterprise Z, which utilizes blockchain technology for supply chain management, is calculated at 92.05% using this model, which is 32.05% higher than the standard value. The conclusion supports the inference of this paper.
