Abstract:
This article aims to investigate corporate governance factors that infl uence the performance in terms of return on equity ratio, return on total assets ratio, net profi t margin ratio, and fi rm value of fi rms listed on the Stock Exchange of Thailand (SET 100). We conducted a quantitative study, collecting data from the annual registration statement (Form 56-1) and the Securities and Exchange Commission of Thailand's information system, focusing on 493 companies from 2019 to 2022. Statistics used for data analysis include maximum, minimum, mean, standard deviation, and multiple regression analysis. The research fi ndings revealed that the size of the board of directors infl uences fi rm performance in terms of the return on equity ratio, the proportion of shareholding by the board of directors infl uences fi rm performance in terms of the return on total assets ratio, and the proportion of independent directors infl uences firm performance in terms of the net profi t margin ratio. However, corporate governance factors have no eff ect on the fi rms performance in terms of fi rm values listed on the Stock Exchange of Thailand.
