In this paper the author studies this problem from the real basis of audit activities, in view of an endless stream of the performance of listed companies notice ＂change＂ phenomenon. The author finds that auditing is the important reasons of listed companies notice ＂change＂, auditor can improve disclosure quality, is the gatekeeper to accounting information. The author also finds that there may be exist collusion of listed company with auditor, SEC should enhance inspection of the implementation of listed companies notice of earnings.展开更多
