公司治理是指一種指導及管理企業的機制,以落實企業經營者之責,並保障股東的合法權益及兼顧其他利害關係人的利益。完善的公司治理制度可以提高董事會的決策品質及財務報表的可靠性,有效地降低代理問題,以提升公司的經營績效與價值;反之企業進行盈餘管理、交叉持股及特權消費等事項都可能傷害股東權益。
有鑑於公司治理議題的重要性,且公司治理是影響公司績效與盈餘管理的重要變數之一,然而相關文獻將公司治理、盈餘管理及公司績效做整合性地研究不多;所以本文主要研究目的在於探討公司治理對公司績效之影響,其次探討盈餘管理對公司績效之影響。
研究對象為台灣證券交易所列之上市半導體公司,研究期間為2011年到2015年,研究結果實證公司治理中董事長兼總經理、董監質押比率、股權集中度與董監持股比率為影響公司績效之重要因素。盈餘管理對公司績效變數(ROA、ROE、EPS) 皆呈負向影響;而盈餘管理對Tobin’s Q反呈正向影響。
有鑑於公司治理對公司績效重要性,本研究建議上市櫃公司應積極取得中華公司治理協會之「公司治理制度評量」認證,除能提高企業的經營品質,創造企業價值,更有助於企業永續經營發展。
