This study explores the impact of corporate governance on the performance and risk of Taiwan semiconductor companies. The empirical results found the financial characteristic variables have a significant impact on business performance. Among them, (1) cash flow ratio, total asset turnover rate and asset size have significant positive correlation with business performance. (2) Debt ratio and capital intensive have a significant negative correlation with business performance. Subsequently, it explores the impact of corporate governance characteristic variables such as shareholding structure, professionalism of directors and supervisors, information transparency, stability of senior management functions, and group control patterns on business risks. The empirical results found that (1) institutional shareholding and shares pledged by directors and supervisors has a significant negative correlation with roa risk, but the deviation between voting rights and cash flow rights has a significant positive correlation. (2) The manager's shareholding has a significant negative correlation with roe risk, but the turnover rate of chief financial officer in the past 3 years has a significant positive correlation. (3) Shareholding of directors and supervisors have a significant negative correlation with business risks, but Shareholding ratio of the controlling shareholders and directors and supervisors ever working for the government have a significant positive correlation. (4) The turnover rate of internal audit manager in the past 3 years and co-operative governance did not have a significant correlation with business risks. Overall shareholding structure does help reduce business risks. Keywords: business performance; business risk; corporate governance; semiconductors.
