Can Reform of Information Disclosure by an Exchange Restrain Corporate Fraud? Evidence from China*

Abstract

This study examines the impact of information disclosure system reform (IDSR) on corporate fraud. IDSR includes the internet-based communication platforms and the introduction of assessment methods for information disclosure. The study finds that reform in the Shenzhen Stock Exchange (SZSE) reduces the probability, frequency, and severity of corporate fraud. In contrast, the reform in the Shanghai Stock Exchange (SSE) has no such effect. The negative association between the SZSE reform and corporate fraud is more evident for firms with weak internal controls and modified audit opinions. This study suggests disclosing companies' ranking in information disclosure assessments to the public to improve governance.
