Corporate Governance debates raised seriously in scandals and financial crisis of recent decades in large companies and banks. The focus of this debate is not merely the corporate governance system, and its main function is to preserve the interests of stakeholders. At the macro level, economic efficiency, sustainable growth and financial stability are important effects of the system. Establishing an efficient corporate governance system in the banking system and evaluating and ranking them requires a comprehensive model that encompasses all the internal and external mechanisms affecting corporate governance and localized indices and relevant international principles. In this research, corporate governance in banks has been evaluated via a model developed in the framework of systematic thinking which includes three dimensions 1) Inputs (structures and inputs), 2) Roles and processes, and 3) Outputs (goals, performance and results of them). The main objectives of this study are to evaluate the compliance status of 27 banks with the indicators of corporate governance model and their efficiency and effectiveness, as well as to examine the correlation between the components of corporate governance within the system including inputs, processes and outputs. According to the results, 47.8% of the qualitative indicators are covered in the current situation of the banks of the country, but there is a significant gap between the full compliance with the model. Based on the results in the performance sector, private banks scored the highest and state banks scored the lowest. The results of evaluating the correlation between the components of corporate governance model showed that there is a positive and significant relationship between the dimensions of inputs and processes with the goals, results and performance of banks. Accordingly, by improving the status of input indicators and the corporate governance model process, the status of target indicators, results and performance of banks will also improve

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.
