本文研究了外資持股與公司治理對公司績效的影響。研究對象為台灣上市櫃電子業，研究期間為2013年至2022年，共計十年。公司績效是以會計衡量指標總資產報酬率 (ROA) 及市場衡量指標托賓Q比率 (Tobin’s Q) 來衡量；外資持股以外資持股率來衡量；公司治理以董事會規模、董事長兼任總經理及獨立董事比率來衡量。本文使用多元迴歸模型來分析，實證結果發現，長期來說外資持股和公司治理提高了台灣上市櫃電子業公司的績效，且研究結果皆為顯著。

This paper examines the impact of foreign ownership and corporate governance on corporate performance in the listed electronics industry in Taiwan for a period of ten years, from 2013 to 2022. Firm performance has been measured using accounting-based measure Return on Assets (ROA) and market-based measure Tobin's Q. Foreign ownership is measured by the percentage of a company’s shares held by foreign investors, and corporate governance is measured by variables which include board size, CEO duality, and the proportion of independent directors. Multiple regression analysis is used as the research method, and the empirical results indicate that foreign ownership and corporate governance positively and significantly affect firm performance in the long run for listed electronics companies in Taiwan.
