Abstract: The current stock market in China is experiencing a crisis amid a prosperous time,as for which many scholars have given their proposals from the perspective of enhancing supervision. This paper believes that there is a certain connection between the exposure of accounting information and securities business supervision. Importantly, an analysis of the agent relation in the process of accounting information exposure is required based on enhancing supervision, in order to establish an accounting information exposure system that is mainly based on market mechanism. A change of macro supervision approach is urged in the hope of systematically assuring the authenticity of accounting information exposure and improving the efficiency of securities business supervision.
