Further, it considers the moderating effect of corporate governance on the relationship between corporate social responsibility and stock price crash risk in Egypt. This research covers seven years period spanning from 2015 to 2021, including a sample of 62 Egyptian listed firms. The ordinary Least Square (OLS) regression analysis is employed to test the research hypotheses.

Further, the results indicate that there is a positive significant direct effect of corporate governance on stock price crash risk.
