各國公司治理方向多以設置審計委員會等功能性委員會為發展重點,台灣之治理監督機構亦將審計委員會列為現階段的推行之重點。本研究以台灣有設置審計委員會之上市(櫃)公司為研究對象,探討設置審計委員會、會計保守性與資金成本之影響。 本研究採用普通最小平方法(OLS)迴歸,來進行研究資料的分析。實證結果發現:1.設置審計委員會與會計保守性呈顯著正相關,表示有設置審計委會之公司,因可以健全公司治理環境,且有效協助及監督公司財務報告,其公司之會計保守性較佳。2.資金成本與會計保守性呈顯著負相關,表示當公司會計保守性較高時,可以降低股東和債權人間的利益衡突,因此能降低公司之資金成本。3.設置審計委員與資金成本呈顯著負相關,表示在良好的審計及監督機制下,可有效降低代理衝突所造成之問題,因此能降低公司之資金成本。
