審計委員會與公司風險承擔相關性

The Relation between Audit Committee and Risk Taking

本研究以最小平方迴歸模型檢測審計委員會與風險承擔的相關性，樣本期間為2004年至2014年。本研究以股東權益報酬率標準差與負債比率衡量風險承擔。研究結果發現，以負債比率衡量風險承擔時，審計委員會之規模、具財務背景之審計委員比率、審計委員會的獨立性三者均與風險承擔呈顯著負相關。而以股東權益報酬率標準差作風險承擔之衡量變數，實證結果發現審計委員會之規模與風險承擔呈顯著正相關；具財務背景之審計委員比率、審計委員會的獨立性與風險承擔呈顯著負相關。 Using the ordinary least square regression, we examine the relation between audit committee characteristics and risk taking for the period 2004-2014. We use two risk taking measures: standard deviation of ROE and debt to assets ratio. Empirical results show that audit committee size, the percentage of financial expert members and the independence of audit committee are negatively related to the first proxy for risk taking - debt to assets ratio. But we find that the second proxy for risk taking- standard deviation of ROE has a positive relationship with audit committee size. As expected, we find that standard deviation of ROE is negatively correlative with the percentage of financial expert members and the independence of audit committee.
