The topic of corporate social responsibility (CSR) has frequently been analyzed, but it slightly relates to banks industry. This study investigates the link between CSR and market valuation in Taiwanese banking industry. To measure CSR, a bank included in CommonWealth magazine is defined as CSR bank, otherwise, it is a non-CSR bank. Regarding market valuation, we consider the short-term and long-term horizon. The empirical results show that CSR is a driver of long-term stock price rather than short-term stock price. Moreover, we find that environmental protection can also explain better long-term stock price. Finally, corporate governance is both highly correlated with short-term and long-term stock price.
