Recently in Mainland China, with the lasting corporate scandals, arguments have been taken up to amend the corporate governance code to provide stronger protection to stakeholders. To see whether companies following different corporate governance standards would have different probability of frauds, this paper study two groups of companies, A-share and H-share companies, which are incorporated in Mainland China but listed in different markets following different corporate governance standards. It investigates whether A-share companies would be associated with lower governance scores and more likely to be involved in scandals than H-share companies. Overall, findings are consistent with the hypothesis that A-share companies score lower in corporate governance and are more associated with corporate scandals. However, the negative relationship between corporate governance scores and corporate frauds is not significant on logistic regression analysis.
