本研究以會計師簽發財務報告日為2017年2月初至2021年1月底，共計四年之美國公開發行公司為樣本，採用Cook, Kowaleski, Sutherland and Zehms (2020)之作法，以會計師所審計之客戶組成中是否含有「公開發行」、「IPO」或「銀行」公司以衡量會計師是否有聲譽敏感客戶，並檢視會計師擁有聲譽敏感客戶與審計品質之關聯。本研究採用績效調整後之裁決性應計項目的絕對值(ABSDA)、可能發生盈餘管理或誤述的機率(FSCORE)與對內控出具不正確意見的可能性(INCORRECT_MW)衡量審計品質。實證結果顯示在會計師客戶組合中，聲譽敏感客戶比例的高低與審計品質沒有顯著關聯。本研究進一步將樣本拆分成四大與非四大會計師事務所，實證結果發現於四大會計師事務所之子樣本中，當會計師客戶組合中銀行業客戶比例較高時，異常裁決性應計項目(ABSDA)會顯著較低。

This study examines the association between the auditor who serves reputation sensitive clients and audit quality. This paper adopts the auditor reputation sensitivity measures, which whether there are “public”, “IPO” or “bank” clients in the auditor’s portfolio used by Cook, Kowaleski, Sutherland and Zehms (2020). This paper incorporates three various dimensions to proxy audit quality, including the absolute value of performance-matched discretionary accruals, the predicted probability of accounting misstatements, and the incorrect material weaknesses. The sample period of this study covers four years, which is the audit report date from the 1st of February 2017 to the end of January 2021. The results show that the ratio of reputation-sensitive clients in the auditor’s portfolio is not significantly related to audit quality. This research further divides the sample into Big Four and non-Big Four firms. I find that in the sub-sample of Big Four firms, when the proportion of banks in the auditor’s portfolio was higher, the absolute value of performance-matched discretionary accruals is significantly lower.
