The role of corporate transparency in determining the relationship between government political support and the performance of the companies listed on Tehran Stock Exchange

This research aims to investigate the role of corporate transparency in determining the relationship between government political support and the performance of the companies listed on Tehran Stock Exchange. The results of analyzing panel data for the years 2003 2010, demonstrate that there is a negative and significant relationship between government political support and information transparency, but according to the results, there is not any significant relationship between government political support and information transparency with ROA. However, when, firm performance is peroxide by Tobin-Q, there is a positive and significant relationship between government political support and firm performance. Results also demonstrate that information transparency acts as a mediating variable in the relationship between government political support and Tobin-Q.In the other words, government political support reduces information transparency and in turn, low transparency caused better performance.
