本研究目的在於比較台灣的集團與非集團企業兩者間,於新上市、櫃當年度之裁決性應計項目盈餘管理與實質盈餘管理行為。本研究係以2001年至2012年間,台灣的新上市、新上櫃公司為研究對象,並基於研究目的採用台灣經濟新報對集團的定義,將樣本公司劃分為集團企業與非集團企業進行比較。裁決性應計項目盈餘管理係參照Kothari et al. (2005)之模型估計,實質盈餘管理則參照Roychowdhury (2006)及Cohen, Dey and Lys (2008)之模式估計。實證結果顯示:台灣新上市、櫃公司於新上市、櫃當年度,集團企業較非集團企業不會有從事裁決性應計項目盈餘管理之行為;另外,在實質盈餘管理方面,實證結果同樣顯示,新上市、櫃公司於新上市、櫃當年度,集團企業較非集團企業不會有從事實質盈餘管理之行為。
