交叉上市、双重审计对境内审计费用和审计质量的影响: 基于我国 A＋H 股的经验证据

This paper chooses Chinese A-share listed firms in the years 2007～2014 to empirically test the impact of A and H shares cross-listing with dual auditing on domestic audit fees and audit quality. Empirical results show that, ceteris paribus, cross-listed and dual-audited companies' domestic audit fees (domestic audit quality) are (is) higher than those (that) of noncross-listed or non-dual-audited companies. Further research suggests that the main conclusion is still valid after controlling for either possible endogeneity problems or the effects of auditor characteristics; the conclusion remains robust in the subsample of observations after the dual auditing system cancellation; in addition, when the auditor is from a “Big4” audit firm, it has a negative influence on the relationship between A and H shares cross-listing with dual auditing and domestic audit fees, while the relationship between A and H shares cross-listing with dual auditing and domestic audit quality isn't affected by whether the auditor is from a “Big4” audit firm or not. The conclusion has some theoretical and practical significance for developing China's institutional environment, auditing cross-listed companies and improving audit quality.
