本研究以財報重編為財報品質之代理變數，探討自由現金流量是否對內部股權結構與財報品質的關係具有調節效果，期望藉助對於自由現金流量調節效果之了解，以利報表閱讀者更適當地解讀財報訊息，瞭解財報之品質。 實證結果顯示，自由現金流量對內部股權結構與財報品質間確實具有顯著的調節效果，尤其是董、監持股率與董事兼任經理人這兩項因素對於財報品質之關係，很受到自由現金流量之影響。自由現金流量本身與財報重編呈顯著負相關，自由現金流量愈高，財報重編的可能性愈低。但自由現金流量所引發的代理問題，反而可能對董、監持股率、董事兼任經理人與財報品質間的關係產生負面的調節效果，即財報重編的可能性顯著提高。但自由現金流量對於經理人持股率與財報品質間的關係不具有顯著的調節效果。 / This study examines whether free cash flow has the moderating effect on the relation between ownership structure and financial reporting quality, using financial restatements as a proxy for financial reporting quality. This study tries to interpret earnings information more appropriately through more understanding on the moderating effect of free cash flow. The study shows that free cash flow exactly has the moderating effect on the relation between ownership structure and financial reporting quality, especially for stocks holding ratio by directors and supervisors and CEO duality. Firms having more free cash flow are less likely to restate statements. However, free cash flow might trigger agency problem, which might having negative moderating effects, causing higher possibilities to restate statements. Otherwise, the finding of this study shows that there is no significantly moderating effect on the relation between managerial ownership and financial reporting quality.
