本研究主要探討中國上市公司內部控制品質與盈餘管理是否有關聯。在本研究中分別使用兩種盈餘管理方式進行實證，結果顯示內部控制品質和盈餘管理程度呈顯著負相關，意即內部控制品質越好，越能抑制公司管理者進行盈餘管理。精確來說，良好的內部控制品質可以抑制管理者利用裁決性應計數美化財務報表，意即好的內部控制可以減少應基礎盈餘管理；在實質盈餘管理方面，本研究發現良好的內部控制品質可以減緩管理者透過過度生產向上盈餘管理，降低管理階層增加裁決性費用已達到預期盈餘目標以及抑制公司透過操控銷貨以影響盈餘之情況，意即好的內部控制能有效減少管理者進行實質盈餘管理。整體而言，本研究結果發現好的內部控制，能有效減少管理者進行應計基礎及實質盈餘管理。 / The objective of this thesis is to investigate whether there is a relationship between internal control and earnings management. In this thesis, I use two types of earnings management: accrual-based and real activities earnings management and I find that there is a significantly negative relationship between quality of internal control and earnings management. Specifically, my results show that high-quality internal control inhibits managers from earnings management through discretionary accruals, implying that high-quality internal control could lower the level of accruals-based earnings management. Moreover, I document that high-quality internal control could reduce upwards real earnings management through increase production, decrease influence through decreasing manipulation discretionary expenses and lessen level of abnormal cash flow. Collectively, I find that high-quality internal control can lower the level of real and accrual-based earnings management behaviors.
