业绩预告偏离度、内部控制质量与审计收费

The Bias of Earnings Forecast,Internal Control and Audit Fee

本文以2010~2014年A股上市公司为研究样本,实证分析了上市公司前期业绩预告偏离度是否会对次年审计定价产生影响,以及高质量内部控制对两者关系的调节作用。研究发现,公司前期业绩预告偏离度与当期审计费用呈显著正相关关系,而高质量的内部控制能够有效缓解这一正相关关系。进一步检验表明,高质量内部控制的调节作用仅在前期业绩预告为乐观偏差时显著存在,同时业绩预告偏离度与下一期获得非标审计意见的可能性正相关,高质量的内部控制同样能够对此起到调节作用。研究结果表明,上市公司业绩预告偏离度是一个有助于审计师进行重大错报风险评估的警示讯号,而高质量的内部控制有助于降低审计风险。

Based on the samples of A-share listed firms in China from 2010 to 2014,we empirically study the rela- tionship between the accuracy of management earnings forecast for the last year and the pricing of audit services, and the influence of internal control quality on the relationship. The results indicate that the bias of management earnings forecast for the last year positively correlated with audit fees, and high-quality internal control can effective- ly reduce this positive correlation. Further research shows that this effect is only significant in the firms that disclose optimistic earnings forecast. Moreover, the lower the accuracy of management bias forecast for the last year, the？ more ？ likely？ the companies will get modified audit opinion, while high quality internal control can also reduce the correlation. The study shows that the bias of earnings forecast is a warning signal helpful for auditors to evaluate major wrong report risks, and high-quality internal control can effectively reduce audit risks.
