Behind the vigorous development of international trade financing is the accumulated risks.In order to alleviate the credit risk of commercial banks in carrying out related business,this paper studies the impact of blockchain technology on the credit risk of commercial banks from both theoretical and empirical aspects.Then,taking the cross-border financial blockchain service platform as a practical case,it analyzes the application effect of credit risk management and control of commercial banks under the platform.The information asymmetry in the game between commercial banks and foreign trade enterprises leads to the problems of constructing false trade background,using documents for repeated financing,misappropriating credit funds,etc.,which are the main sources of credit risk of commercial banks.The consensus mechanism,distributed storage,asymmetric encryption and traceability of blockchain technology can alleviate the problem of information asymmetry.This paper uses non-performing loan ratio to measure the credit risk of commercial banks,constructs the index of blockchain technology development level through "text mining method" and "factor analysis method",measures the degree of information sharing with credit information coverage,and constructs a model based on the panel data of 21 commercial banks from 2009 to 2018.Regression analysis results show that there is a significant negative correlation between the development level of blockchain technology and the credit risk of commercial banks,and the degree of information sharing has a complete intermediary effect.Based on the above theoretical and empirical research,this paper takes the cross-border financial blockchain service platform as an example to analyze the process of export accounts receivable financing.It is found that blockchain technology can effectively alleviate the problem of information asymmetry between banks and enterprises,reduce the possibility of false financing and repeated financing,and thus reduce the credit risk of commercial banks in trade financing business.In order to promote the application of blockchain technology in alleviating the credit risk of commercial banks,the following measures can be taken in the future: expanding the main scope of blockchain platform,enriching the application scenarios of blockchain platform,deepening the technical research of blockchain platform,etc. |
