Specifically, we examine the relation between firms’ pre-COVID-19 corporate social responsibility (CSR) scores and their post-COVID-19 performance and risk. Using a sample of 1685 non-financial firms listed on the Taiwan Stock Exchange, the empirical results show that firms with high-CSR scores have higher abnormal returns, better operating performance, lower stock price volatility, and less idiosyncratic risk relative to those of low-CSR firms. The results are robust to various sensitivity tests. We also find that the results are mainly driven by the overall CSR investment rather than individual CSR activities.zh社會資本企業社會責任COVID-19 疫情危機Social CapitalCorporate Social ResponsibilityCOVID-19 Pandemicmaster thesis
