Then the author use the statistical method to demonstrate the credit risk in a certain commercial bank, including analysis of the index of loaning quality, analysis of the index of decentralization and analysis of mortgage, then the high rate of idle loans and bad loans, over-centralized loans and low rate of mortgage loans reflected low-grade on the quality of credit of the bank.Then in chapter two, the author pointed out that the original cause of formation of the credit risk can be divided into outside reason and inside reason.
