債權人在考量借款給公司所面臨的風險時，不只應考慮公司過去信用狀況，更須了解一家公司之公司治理對於未來現金流量穩定性有相當的影響力，故本研究探討公司治理對信用風險之影響，檢視良好的公司治理是否比較差的公司治理擁有較佳之信用風險評等。 　　研究發現，在控制公司特性之後，信用風險評等和十大股東持股比例、集團企業與否呈現負相關，顯示十大股東持股比例高與公司為集團企業時信用風險評等表現較差；與法人持股比例、經理人持股比例、資訊揭露透明度、獨立監察人比例、董事會持股比例呈現正相關，顯示法人持股、經理人持股、資訊揭露透明度、獨立監察人與董事會持股等比例的提高時有助於信用風險評等提升。 　　公司若提升公司治理，將擁有較良好的信用風險評等，債權人會因不確定性的減少而要求較低之必要報酬率，同樣減輕了企業的債務負擔，但有許多公司並未因此而加強其公司治理制度。研究中發現，當獨立董事比例低與董事會持股比例低時，平均董監薪酬水準顯著較高，可見在公司治理較差時，董監反而得到較高之薪酬，解釋了公司治理機制無法完善的原因。

本研究從家族治理、機構投資人持股、董事會組成、董事會效能之角度探討公司治理機制對企業績效與董監薪酬之影響。家族治理方面，家族持股愈多，企業績效愈好，但家族參與經營程度愈高，企業績效卻愈差；而家族治理下，董監薪酬水準、薪酬績效連結性均較低。機構投資者方面，本國金融機構持股愈高，企業績效愈高。董事會組成方面，董事長兼總經理下，企業績效較差、董監薪酬績效連結性較低，而執行董事、獨立董監席次比例愈高，企業績效、董監薪酬績效連結性均愈高；董事長兼總經理下及執行董事席次比例愈高時，董監薪酬水準愈低，而獨立董監席次比例愈高，董監薪酬水準愈高。董事會效能方面，正常營運下之企業，董事會開會次數愈多、出席率愈高，企業績效均提升；董事會出席率愈高，董監薪酬水準、薪酬績效連結性均愈高。 / The study uses family governance, institutional ownership, board structure, and board activities to empirically investigate the influence of corporate governance on firm performance and board compensation. Empirical result shows that the firm performance is higher when family ownership, institutional ownership, executive directors, independent board members, and board activities increase, and that the firm performance is lower when family involvement increase and when chairman and CEO is the same person. In addition, the board compensation is higher when independent board members and board activities increase, and the board compensation are lower when family governance, institutional ownership, executive directors increase and when chairman and CEO is the same person. Moreover, the pay-performance sensitivity is higher when institutional ownership, executive directors, independent board members, and board activities increase, and the pay-performance sensitivity is lower when family governance increase and when chairman and CEO is the same person.

本研究主要探討我國上市櫃公司的董監薪酬影響因素，採用新制董監薪酬揭露制度，將董監事兼任經理人、兼任員工的薪酬與分紅排除後，以董監薪酬合計和平均董監薪酬作為研究對象。本研究以2005年至2013年所有上市上櫃(含下市下櫃)的公司為研究樣本，並使用普通最小平方法則和固定效果模型進行檢測影響董監薪酬因子。 研究結果發現我國上市櫃公司的董監薪酬確實受到董事會特性、公司特性以及公司經營績效影響。董事會特性中以董事會規模、董監事持股比例和董事兼任經理人比例具有顯著之影響；公司特性以公司規模、負債比例、股價日報酬波動度和投資機會均對董監薪酬具顯著影響；最後，公司經營績效指標中以Tobin's Q、資產報酬率、營業收入淨額與股利殖利率與董監薪酬呈顯著正向影響。這表示我國公司在制定公司董監薪酬時，確實會考量其董事會特性、公司特性以及公司之經營績效。 最後，本研究使用迴歸式的殘差項由大至小組合投資組合以觀察其績效表現，殘差項最大(小)投資組合表示支付過高(低)董監薪酬的公司，研究發現並無法從投資組合的績效表現看出支付過高(低)董監薪酬對公司股價報酬表現之影響，本研究認為這可能是因為支付過高董監薪酬可能同時包含因為該公司的董監事之能力佳而支付較高的薪酬亦可能該公司的董監事僅為坐領高薪的肥貓。 / This study empirically examines variables that influence director compensation of Taiwanese companies. With new disclosure rule for board compensation, we exclude the salaries and bonus of concurrently serving as managers or employees, and divide board compensation as total director compensation and average director compensation. We collect 2005 to 2013 listed companies on Taiwan Stock Exchange and Taipei Exchange as research samples. In our regression analysis, we distinguish three types of determinants: board characteristics, firm characteristics and corporate performance. Using ordinary least squares estimator method and fixed effect method, our results show that board characteristics, firm characteristics and corporate performance do affect board compensation. We find board size, directors’ equity holding ratio and the ratio of director concurrently serving as manager that significant influence director compensation. From the aspect of firm characteristics, results show that firm size, leverage ratio, daily stock returns volatility and investment opportunity also significant influence director compensation. We also provide evidence that higher Tobin’s Q, ROA, sales and dividend yield, higher director compensation. Finally, we use residuals from the regression to construct portfolios and observe their performance. The portfolio with highest (lowest) residuals considers as companies overpaying (underpaying) their directors. However, from performance of portfolios, we cannot conclude that directors are overpaid or underpaid can reflect companies future performance, since directors are overpaid may because of their extraordinary ability or simply because they are fat cats.
