Abstract
The impact of corporate governance on risk has been studied in different researches and has led to different results. To justify these conflicting results, the impact of corporate social responsibility moderation was assessed by Lee et al. (2016), which showed that corporate social responsibility has a moderating effect on the relationship between corporate governance and firm risk. Considering the cultural and economic differences in different countries, this research aims to help risk management, has examined this issue in companies listed on to the TSE. the hypotheses were tested using regression method on panel data. Investigations on 104 companies during the period of 2004 to 2015 showed that the ratio of non-executive directors, the board size and the company's social responsibility are positively related to the company risk. Also, social responsibility of the company moderates the relationship between the corporate governance criteria and the company's risk, and with the introduction of social responsibility variable, an increase in the ratio of non-executive directors and the number of board members leads to risk mitigation.
