摘要


本研究主要以我國資本市場資料中,去篩檢公司之查核報告書被出具修正式無保留-分攤式查核意見,以其分析會計師採用其他會計師之比例多寡,是否會去影響其審計品質。實證結果顯示當公司收到分攤式意見機率越高,其異常應計數數值較大,乃因有部份並未經會計師查核,而選擇採用其他會計師之查核報告,藉此分攤部分責任及規避審計失敗而衍生之訴訟風險,換句話說,採用其他會計師意見比獨自簽核審計意見的會計師所出具查核報告書,其審計品質相對來的低,且審計訴訟風險之機率可能會顯著提高。而在分攤比例部分,本文將樣本區分成資產與收入兩子層面研議,從實證中顯示加入會計師分攤比例後對其實證結果有顯著影響,尤其在資產面未查核比例更高於收入面未查核比例,另外更發現當會計師未查核比例越高,分攤式意見被出具之可能性越大,表示會計師出具分攤式意見,乃基於保守原則,對於未查核比例較高時或是他人查核品質較無法輕易控管時,會計師更不願去承擔他人查核責任,更從實證中獲得一致認同。除此本研究與傳統觀念不太相同的是,會計師對向下盈餘管理比對向上盈餘管理更敏感,本文推測,有可能是因為會計師對於盈餘向下調整視為一種潛在危險信號。最後,本文實證結果可以彌補相關不足文獻,並對其相關制定政策之機關提供參考。

並列摘要


In this study, we use Taiwan's capital market data to investigate the impact of shared audit opinions and share ratio in audit reports on audit quality. We apply discretionary accruals as a proxy for audit quality and examine share ratio in asset and revenue perspectives. Our empirical results show that audit reports with share audit opinions have more discretionary accruals which mean an audit report issued solely by an auditor are of greater audit quality relative to that issued by more than one auditor. Besides, we find that an accountant is more likely to issue audit reports with shared audit opinions when the manipulation accruals and the unaudited partition become relatively large and high. Furthermore, the evidences in our study reveal that earnings downward adjustment is more sensitive than upward adjustment to the surplus for accountants in the issuance of shared audit opinions. Besides, our suggestion not only makes up for the existing literature in manipulation accruals with audit opinions but also provide reference to the policy for government institutions recently.
