本研究主要目的有二。首先,探討與財務報導有關的內部控制(Internal control over financial reporting, 以下簡稱ICOFR)的品質不佳時,是否會降低財務報導的可靠性、盈餘穩健性、盈餘價值攸關性等三種財務報導品質。第二,探討董事會及會計師兩種與財務報導有關的內部控制監理機制,是否可改變ICOFR對財務報表可靠性、盈餘穩健性,以及盈餘價值攸關性之間的關聯性。 本研究以1998年至2006年為研究期間,3664筆觀察值為研究對象,使用公開說明書中具有「會計師提出最近三年內部控制改善建議」的資料作為ICOFR品質的衡量方式,並分別以修正式Jones模型所計算的裁決性應計數、Dechow and Dichev (2002)應計雜訊模型所計算的應計雜訊、經Ball and Shivakumar (2005a)修正之Basu模型以及盈餘反應係數模型,作為探討ICOFR對財務報導可靠性、盈餘穩健性及盈餘價值攸關性之研究方法。研究結果發現,ICOFR的品質不佳時,會產生較大的裁決性應計數及應計雜訊,代表財務報導之可靠性會因而降低。本研究尚發現ICOFR的品質不佳時,盈餘中的暫時性損失之持續時間較長,代表盈餘較不具穩健的特性。然而,ICOFR的品質不佳時,並不會降低盈餘對股票報酬的解釋能力。此外,本研究進一步將內部控制資料加以分類,發現交易循環之內部控制缺失是造成財務報導品質降低的主要因素。其次,本研究以董事會及會計師作為兩種內部控制監理機制,發現兩者皆無法改變ICOFR對應計品質及盈餘穩健性之影響,然而會計師之監理能力卻能改變ICOFR對盈餘反應係數之負面效果,進而提升盈餘之價值攸關性,最後,本研究以Fama MacBeth (1973)之橫斷面迴歸模式為基礎之敏感性分析結果與上述結論相似。
This paper, based on 3664 observations with internal control deficiencies reported from 1988 to 2006, investigates the relation between financial reporting quality and internal control over financial reporting. My research employs quality of accrual to measure reliability of financial reporting and find that, firstly, firms with internal control deficiencies reported get lower quality of accrual in terms of discretionary accruals and accruals noise than those without internal control deficiencies reported. Secondly, firms with internal control deficiencies reported are usually with higher persistence of transitory loss components in earnings as well, and, therefore, has lower earnings conservatism; however, my research doesn’t show that firms with internal control reported deficiencies have lower earnings value relevance. Thirdly, the effect of internal control deficiencies on financial reporting quality is mainly from that of transaction cycles. Finally, governance mechanism of internal control either from board of director or accounting firm can’t change the impact of internal control deficiencies on all financial reporting quality while accounting firm can improve the relation between earnings value relevance and internal control over financial reporting. Collectively, the results are supported by cross- sectional regression of Fama MacBeth.
