本研究以89年至93年間適用批次審查簡化作業之上櫃轉上市公司為研究對象,樣本公司共計176家。因樣本公司申請轉上市前一年度及轉上市當年度有盈餘管理動機,所以本研究以樣本公司申請轉上市前一年度及轉上市當年度財務資料為觀察值,合計352個觀察值,探討大型會計師事務所相較於非大型會計師事務所與產業專精會計師事務所相較於非產業專精會計師事務所是否越會抑制轉上市公司利用裁決性應計數進行盈餘管理的能力來衡量審計品質。本研究實證結果發現,(一)大型會計師事務所相較於非大型會計師事務所不能越會抑制轉上市公司利用裁決性應計數進行盈餘管理的程度。(二)由產業專精會計師事務所查核之轉上市公司其裁決性應計數的程度低於由非產業專精會計師事務所查核之轉上市公司,而這種關係主要係產業專精會計師事務所越會限制轉上市公司向下操縱盈餘所導致。(三)針對結果(二)進一步比較分析轉上市前一年度及轉上市當年度資料發現:轉上市前一年度,產業專精會計師事務所相較於非產業專精會計師事務所不能越會抑制轉上市公司利用裁決性應計數進行盈餘管理的程度;但轉上市當年度,由產業專精會計師事務所查核之轉上市公司其裁決性應計數的程度低於由非產業專精會計師事務所查核之轉上市公司。
In this research, we targeted on the GTSM-TWSE Transfer Companies applied with simplified batch review between 1990 and 2004. The population is 176 companies. Since the companies in the population had the motives in earnings management the year before and current year of GTSM-TWSE Transfer, therefore this study consists of 352 observations of 176 transferring firms to examine whether auditor size (measured by big5) and industry specialization are associated with lower earnings management during the year before and the current year of GTSM-TWSE Transfer. The empirical findings of this research are: 1) Big5 can not constrain transfer listing firms’ discretions over earnings than non-big5. 2) Transfer listing firms audited by industry specialist auditors engaged less in earnings management than transfer listing firms audited by non-industry specialist auditors, that is driven by industry specialist auditors’ tendency to limit transfer listing firms’ income decreasing–accruals. 3) Based on the finding 2), it is found that by comparing the data of the companies one year before and the current year of transferring into TWSE ,on the year before transferring, the industry specialist auditors can not constrain transfer listing firms’ discretions over earnings than non-industry specialist auditors , but on the current year of transferring, transfer listing firms audited by industry specialist auditors engaged less in earnings management than transfer listing firms audited by non-industry specialist auditors.
