Abstract
The increase in greenhouse gas emissions is one of the crises in today's world. Because it doubles global warming and environmental pollution. The increase in greenhouse gas emissions has encouraged many countries to substitute renewable energy instead of fossil fuel. The effective use of green energy such as renewable energy and nuclear energy is highly dependent on the technology used in the production of this type of energy. For this reason, the aim of this study is to investigate the impact of importing information and communication technology goods on renewable energy production in Iran. In this research, has been used the Computable general equilibrium model based on the social accounting matrix of 2014. The results show that in all scenarios, the production of fossil electricity in both peak and base times, as well as the production of ICT goods, will decrease because with the release of the import of these goods, foreign ICT goods will replace domestic ones and the production of these goods will be domestic. Also, the production of other sectors has increased and the largest increase is related to the gas sector. By applying the first scenario (10 to 100% change in tariff, without change in the productivity of production factors related to the production of renewable energies), with the further reduction of the tariff, the production of renewable electricity will also decrease in both peak and base times, but when The fact that the import of ICT goods is accompanied by a 3, 5 and 7 percent increase in the productivity of the production factors related to the production of renewable energies (scenarios two to four) will increase the production of renewable electricity in the base load. The production of renewable electricity at peak load has decreased in all scenarios and the results do not change with the increase in efficiency. By reducing the tariff on the import of ICT goods, the amount of CO2 emissions will decrease. Also, as the productivity of the production factors related to the sector of renewable energy production increases, CO2 decreases to a greater extent. It should be noted that with the reduction of the tariff on the import of ICT goods, the price of the goods has decreased in the investigated sectors. As a result, reduce the pollution caused by the consumption of fossil fuels and use them optimally.

Abstract
Today, information and communication technology affects all aspects of human life. The result of which is a transformation in all methods of production and distribution to education, exchanges and human relations. On the other hand, the requirement for the realization of economic development and growth is the higher growth rate in poor and underdeveloped areas than in rich and developed areas, which is proposed as the hypothesis of convergence. In this regard, regional inequalities are a fundamental challenge for the development of regions and these inequalities are a serious threat to create a balanced development of regions. Therefore, the main goal of the current study is to investigate the convergence of Fava among the provinces of the country. The results using the Nahar and Inder method during the period of 2002-2013 showed that out of the 30 investigated provinces, divergence in land use occurred in 22 provinces. Also, at the infrastructure level, the average slope of 31 provinces is positive, but the t-value is significant for the provinces of South Khorasan, Khuzestan, Alborz and Fars, which shows that digital divergence has occurred in these provinces during the period under review. Therefore, it can be seen that although in terms of infrastructure, we have had less divergence at the level of the provinces, but in terms of usage, this gap and divergence has increased.
