The separation of ownership and management is one of the biggest characteristics of the stock company. One of the main reasons for the information disclosure of the modern company is to solve the problem of information asymmetry caused by the separation of the two rights. The owner of the company needs to understand the operation of the company through the accounting information disclosure materials prepared by the company's operators, and supervise the operators to fulfill their duties. If the managers of the company deliberately conceal the real business situation of the company, it will lead to the distortion of accounting information, making the owners unable to make correct decisions, which will damage the rights and interests of the owners of the company. The management of listed companies regards information quality as the main basis for managers to make some major investments or decisions, so it is a top priority to ensure the quality of accounting information. The correct accounting information can also make the management of the company further enhance the efficiency of corporate governance, and the correct corporate governance can also improve the quality of accounting information to a certain extent. If the enterprise does not establish a set of relatively standardized control mechanism, which can not restrict the behavior of the relevant personnel, the accounting information can not reflect the company's operation status in a timely and real way, reduce its control ability, thus resulting in the continuous decline of its quality.
