چکیده [English]

The present study investigates the relationship between governmental affiliation and firm`s systematic risk. In this study, data have been gathered from 76 listed companies in Tehran Stock Exchange from 2005 to 2015 and the research hypothesis has been examined by utilizing the regression coefficient analysis. The results indicate that there is a direct and significant correlation between governmental affiliation and systematic risk. In other words, companies which depend on government may encounter political risk and it can be one of the effective factors on the systematic risk. According to Levine (2005), governmental managers affect the firm`s risk by political decorum. Therefore, governmental affiliation can be used as a significant variable in firm`s risk.
