In June 2008, the Ministry of Finance, the China Securities Regulatory Commission, the National Audit Office, the China Insurance Regulatory Commission and the China Banking Regulatory Commission jointly issued the Basic Guidelines for Enterprise Internal Control (hereinafter referred to as the new guidelines), which stipulated that it would be implemented within the scope of listed companies from July 1 2009, and encouraged large and medium-sized non-listed companies to implement it, requiring listed companies to conduct self-evaluation on the effectiveness of internal control and disclose annual self-evaluation reports, indicating that the company's internal control system has been established and improved. At this point, the disclosure of internal control information has changed from non-mandatory to mandatory. Internal control information belongs to qualitative information, and the quality of internal control information disclosure of listed companies directly affects the acquisition of investors' information, which is the information basis for investors' investment decisions. The internal control information disclosure of listed companies in China has gone through a process from scratch, and the quantity and quality of information disclosure are constantly improving, but compared with quantitative accounting information disclosure, it is still in its infancy, and many problems will arise in its implementation.
