在過去的研究大多以帳面價值及每股盈餘來衡量公司股價，鮮少討論公司治理變數對公司股價的影響，本研究以Ohlson(1995)所提出股權評價模型為基礎，加入公司治理變數，並以台灣上市櫃公司金融業為研究對象，金融業為高度監管產業，公司治理重要性更加顯著。研究時間為2010至2019年財報資料，探討加入公司治理變數後是否能增加變數解釋的能力。公司治理變數包含前兩大股東持比例、第二代股東持股比/第一大股東持股比、外部董事比例、機構董事比例、轉投資家數、轉投資比例、參與管理、董監持股比例、董事會穩定以及經理人持股比例，以主成分分析(Principal components analysis)分類成分，總共分為五類，再以逐步迴歸篩選顯著之主成分。
本研究發現顯著之變數為外部董事比例、轉投資家數、前兩大股東持股比例，外部董事比例及轉投資家數與公司價值成反比關係，代表外部董事監督能力受到質疑，轉投資項目增加也會增加成本使價值下降。前兩大股東比例則與公司價值成正比，顯示前兩大股東對公司有監督效果，使公司價值提升。

In the past, most studies used book value and earnings per share to measure company stock prices, and rarely discussed the impact of corporate governance on company stock prices. This research is based on the equity evaluation model proposed by Ohlson (1995), adding corporate governance variables, and taking the financial industry of Taiwan listed companies as the research object, the financial industry is a highly regulated industry, and the importance of corporate governance.
The research period is the financial report data from 2010 to 2019, to explore whether the ability to explain the variables can be increased after adding the corporate governance variables. Corporate governance variables include the ratio of the first two largest shareholders, the second-generation shareholder's shareholding ratio/the largest shareholder's shareholding ratio, the ratio of outside directors, the ratio of institutional directors, the number of reinvestors, the ratio of reinvestment, participation in management, and directors’ and supervisors’ shareholding ratio, board stability, and manager's shareholding ratio are classified into five categories by Principal Components Analysis, and then the significant principal components are screened by stepwise regression.
This study found that the significant variables are the proportion of external directors, the number of reinvestors, and the shareholding ratio of the top two largest shareholders. The proportion of external directors and the number of reinvestors are inversely proportional to the company’s value. This means that the supervisory ability of external directors is questioned and the reinvestment project an increase will also increase the cost and decrease the value. The ratio of the first two largest shareholders is directly proportional to the company's value, which shows that the first two largest shareholders have a supervisory effect on the company and enhance the company's value.
