會計師傾向與收入認列之關鍵查核事項

The Effect of Internal Governance and External Monitoring Mechanism on Firm Value

會計師特質影響審計結果，但文獻僅證實會計師的產業知識影響審計品質，尚未實證會計師個人傾向對審計品質的影響。本研究實證關鍵查核事項係反映會計師之傾向，抑或是反映受查公司之審計風險。研究設計以2016年關鍵查核事項溝通收入認列議題之情形，作為衡量簽證會計師傾向之代理變數；受查公司2017年審計風險之衡量，則為該公司自行認列之全年收入數，與審計簽證核定年收入數間之差異。研究結果顯示2017年關鍵查核事項係反映會計師2016年之傾向，而不是反映受查公司2017年之審計風險。改用二階段迴歸以減輕內生性，或使用不同方式衡量主要變數，仍得到相似的結論。

Audits' characteristics are critical to the results of auditing. Prior studies find that audits' expertise in industries affects auditing quality. However, the literature does not examine how auditors' tendency affects auditing quality. This study empirically tests whether auditors' tendency or companies' audit risks determine the contents of key audit matters (KAMs) for the year of 2017. Our research design measures auditors' tendency by the contents of their KAMs for the prior year (i.e., 2016) regarding revenue recognition. We measure companies' auditing risks by the differences in revenues for 2017 between companies' filed numbers and audited numbers. Empirical results indicate that the contents of 2017 KAM reflect auditors' tendency but not companies' auditing risks. This conclusion remains valid even when we use two-stage regressions to mitigate endogeneity, and when we use different measures of the key variables.
