Credit decision is one of the major businesses for banks, and it plays a vital role for a bank ’ s development. It is of vital importance to improve the identification accuracy of debtors financial situations, though there are many tools for financial data analysis. Support vector machine (SVM), a technique of artificial intelligence, has a relatively high accuracy for solving binary classification problems with small samples. This paper used ST (Special Treatment) together with an improvement of long-term loans for two consecutive years and non-ST (never under special treatment) of Chinese listed companies as two classes of financial situations and employed financial indicators as variables to construct SVM models for banks credit decision-making, along with the discussion of related recent patents. Our conclusion is that SVM has relatively higher classification accuracy than some other classifiers, including neural network, decision tree, and discriminant analysis. Therefore, application of SVM to bank credit decision-making is feasible and efficient. The review also discussed relevant patents.
