Information flow is a key parameter in an economic activity that acts as the main factor in the capital market emergence, stability, and efficiency. The purpose of the current research is to investigate the effect of the environmental points of cooperate governance on the pricing of information asymmetry. In this regard, we have extracted data related to companies accepted in the "Tehran Stock Exchange" from 2009 to 2018, and a panel-data regression model was utilized to test research hypnosis. The results show that information asymmetry and environmental points of cooperate governance have a significant effect on the expected return (cost of capital) on an investment. In addition, the effect of environmental points of cooperate governance on the relationship between the information asymmetry and the cost of capital has been verified. Finally, the results show that environmental points of cooperate governance leads to the differences in the cost of capital in the different levels of information asymmetry.
