This paper is concerned with the analysis of the creditor＇s ability to collect, analyze and judge business information, which is a realistic problem for the bank to control the risk of loan effectively. We not only know the bank＇s application of financial and non-financial information during the process of credit extension but also investigate the use of non-financial information by questionnaire. It is discovered that the bank even believes the information that directly acquired by itself while collecting, analyzing and judging the reliability of business information. Through some sensitive information such as the changing of accounts receivable and cash flow and the connection trade, it can predict the potential risk further. In addition, the results show that it is the perfection of internal control system of intermediary （such as accounting firm） and the business enterprise itself that make the bank get the true information of business enterprise.
