Effort Allocation in Integrated Audits and Implications for Financial Reporting Quality
研究了整合审计中审计师在内部控制与财务报表审计之间的努力分配如何影响财务报告质量，发现增加对内部控制的依赖会降低财务报告质量，但客户重要性可缓解此负面效应。
SUMMARY This study investigates the implications of effort allocation in integrated audits on financial reporting quality. We examine whether increased-reliance on internal controls, defined as auditors allocating greater effort to the audit of internal controls and less effort to the financial statement audit, relative to expected levels of effort, negatively impacts financial reporting quality. Based on a sample of 9,094 firm-year observations from companies listed on China’s stock exchanges during 2012–2019, we find evidence that increased-reliance on internal controls is associated with lower financial reporting quality. However, client importance mitigates this negative effect. Our main findings are robust to controlling for endogeneity, excluding observations whose abnormal audit fees are close to zero, and using a sample with stable total audit fees over time. Overall, our findings suggest that disclosure of fees related to internal control audits and financial statement audits provides information relevant to assessing financial reporting quality.
