The results indicate that the impact of financial and banking development indices on economic growth is different for economic growth rates above and below 6%. Therefore, if the economic growth rate is higher than 6%, then we have a regression and when economic growth is lower than 6% will have another regression in order to effect of financial development of economic growth.

- چکیده:
- چکیده انگلیسی: Considering oil-rich status of OPEC member countries, abundance of energy resource and its low cost, environmental quality is at low level due to production and extraction of energy resources. Iran is also a part of this collection, thus, the higher greenhouse gas emission in these countries makes more problems for the human beings and other creatures and control, and observation of standards in this regard becomes more important than ever. Therefore, the present study was conducted to investigate the relationship between carbon dioxide emissions and economic growth with emphasis on the social welfare index of OPEC member countries. To this end, the data of OPEC member countries from 2000 to 2014 were analyzed using the data panel approach. The results showed that CO2 emissions have a positive and significant relationship with the economic growth of OPEC member countries, which means that the higher the CO2 emissions, the higher the nominal growth. However, when the relationship between CO2 emissions and economic growth is calculated by emphasizing the welfare index, it shows that this effect is declining. It means that the effect of pollution on declining welfare ultimately reduces the rate of economic growth. Give. Therefore, countries should take a constructive step in improving economic growth and reducing pollution by improving the quality of the environment and creating a suitable foundation for realization of this goal, because one of the main goals of societies and governments is to improve the welfare of society.

After designing information asymmetry evaluation indicators, the transaction information has been collected from the Stock Exchange in the five year period of 2011-2015. A statistical sample of 155 companies was selected using a systematic elimination method, which was a total of 775 years-firm. In this research, linear regression and correlation were used to analyze the hypotheses of the research. What can be said in the summing-up and conclusion of the general test of research hypotheses is that the company with a higher information asymmetry is less likely to pay dividends, as well as government-affiliated companies with higher information asymmetry pay more dividends compared to non-governmental corporations. Finally, the results indicated that structural reform in order to increase the transparency of information leads to a positive moderating effect on the relationship between information asymmetry and dividend policies
