本研究探討臺灣上市櫃公司之集團企業盈餘品質,透過建立「資訊不對稱假說」及「應計數抵銷假說」分析集團企業之盈餘品質係受何種因素影響。在「資訊不對稱假說」下,集團企業因多角化後而產生的複雜結構,導致報表使用者需要?多資源與專家,否則難以詳細檢閱公司的財務報表,代?問題因而產生,使得集團企業盈餘品質較差;而「應計數抵銷假說」係從內部資本市場觀點??,多角化公司內部籌資應較有效?,因此多角化公司的管?者在處?應計?上應該會有?多彈性。但因為?同部門的應計?關?性低,甚至會互相抵銷,管?階層難以操縱盈餘及其方向,但集團企業之各分子公司間有許多分子公司之財務資訊係未編入集團合併報表內,因此,應計數抵銷假說未能完全適用於集團企業之研究。本研究以應計數之持續性、盈餘管理及盈餘穩健性衡量集團之盈餘品質,研究結果一致顯示集團企業之盈餘品質較非集團企業差。
This study aims to investigate whether Taiwanese business group firms’ earnings quality. The motivation of this study is that it is presumably more difficult for the public or even analysts to carefully scrutinize the business group firms’ earnings reports because of the complicated structure of business group firms. It may result in information asymmetry between management and investors. This study uses accrual persistence, earning management and conservatism to gauge the earnings quality of business group firms and non-business group firms. The empirical results show that business group firms’ earnings quality are poor than non-business group firms.
