Renewable energies are more compatible with the environment and their preparation and production have less pollution. In addition, since there is no end in sight for this type of energy, renewable energies take on a greater share in the world's energy supply system day by day, even in countries with fossil energy. The purpose of this research is to investigate the factors affecting the consumption of renewable energy in OPEC member countries using the panel data approach in the period from 2004 to 2018. In this research, the effects of factors such as good governance index, human capital, intensity of carbon dioxide emission, income (GDP) and crude oil price were investigated. The results of estimating the model using the feasible generalized least squares (FGLS method indicated that the good governance index, human capital, carbon dioxide emission intensity and income (GDP) have a positive and significant effect on the consumption of renewable energy in OPEC member countries, but the price Crude oil has no significant effect on the consumption of this group of energies in the mentioned countries. Factors such as the high cost of establishing renewable industries in OPEC member countries and the dependence of these countries' economies on oil revenues can be considered among the reasons for this result.

The National Development Fund was established as a development fund with the aim of providing intergenerational benefits, preventing the spread of fluctuations in oil revenues to the economy, and also supporting the country's development plans. Despite this, until now, there has not been a detailed evaluation of how the allocation of resources of this fund affects macroeconomic variables. However, by studying and examining the successful global models of such funds, in addition to the limited impact of this fund on the macro-economic variables in Iran, there are also flaws in the way its resources are allocated. Based on this, the main goal of this research is to design a dynamic stochastic general equilibrium model to evaluate the impact of the allocation of National Development Fund resources on macroeconomic variables with the Bayesian estimation approach using quarterly data for the period 2011-2021. The results of the simulation show that if the National Development Fund spends part of its resources on direct and indirect investment, although at the beginning of the period (about one year) its effects are the same as before (only facilities), but after that the level of production, capital and investment will increase, which will lead to higher economic growth. Also, the results obtained from the minimum variance portfolio method show that among the existing methods, buying shares of capital market companies directly and investing in various types of investment funds, can bring higher returns than the current method (facilities) for the Fund at a certain level of risk.

This paper focuses on the analysis of the petrochemical products manufacturing value chain and the presentation of petrochemical products' optimal manufacturing pattern in petrochemical industries affiliates of pension funds. The case study in this research is JAM and MASJIDSOLEYMAN Petrochemical companies. Period of this research is 5 years. In this case study, the determiner faces paradoxical objectives simultaneously. The fuzzy multi-objective linear programming (FMOLP) method has been used based on the α-cut of fuzzy parameters in this research. The goal of this research is to extract the amount of products that have maximized profit and value-added and minimized risk simultaneously which face technological, market, financial, budget, legal, and national interest-related limitations. This method is often interested in the proper POSs that have finite tradeoffs between objective functions. One numerical sample has been used to show the possibility of using the said method in multi-objective optimizing issues for the production of propylene. Because of the efficiency and satisfaction of the obtained new solutions for this method, this method undoubtedly can be useful to solve the FMOLP problems. A decrease in the production of ethylene and light polyethylene and an increase in propylene and butadiene production is the most important policy recommendation of this research.

The characteristics of crude oil and the factors affecting the price of this energy carrier have made its price forecast always considered by researchers, oil market participants, governments, and policymakers. Because the price of crude oil is affected by many factors, ongoing studies should be done to make more accurate and reliable estimates over time. In this paper, a combination of GM (1,1) and ARIMA models and a hybrid model (GM-ARIMA) for crude oil price forecasting is proposed. The Brent crude oil price data for seasonal (2015Q1-2021Q2), monthly(2020m3-2020m12), and weekly(w12-2020: w16-2021) periods were used to examine this method. The results show that based on the evaluation criteria of mean absolute error percentage (MAPE) and square mean square error (RMSE), the evaluation criteria of MAPE and RMSE in the combined GM-ARIMA model are always lower than the GM and ARIMA models alone. Therefore, the GM-ARIMA hybrid model will be able to predict more accurately than the GM and ARIMA models. Therefore, for more accurate prediction, the GM-ARIMA hybrid model can be used instead of single models.

Investigating the effects of climate change on different aspects of social life has been the focus of research in recent decades. The importance of energy for development and growth as well as pollution caused by energy carriers has made it necessary to assess the impact of climate change on the consumption of various energy carriers including natural gas. This study designed a model for natural gas demand in which in addition to the conventional economic factors, climate variables are considered. Then, we estimate this model for Iran during the years 2003-2015. In addition, variables of GDP and electricity consumption as well as trend variable had the greatest effect on natural gas consumption in the country.

Economic sanctions in the field of international relations affect the trade pattern of countries. One of the effective channels of sanctions is exports (as the most important source of foreign exchange supply for countries). In this regard, oil exports to OPEC member countries, especially Iran, are among the most important economic revenues and have a high share in the country's budget. In the present study, the effect of sanctions on the pattern of trade in Iranian crude oil and petroleum products and also the effect of these sanctions on OPEC member countries in the framework of the generalized gravity model using panel data econometric models have been investigated. The research model is based on statistical data from 1988 to 2018 in the form of four periods of sanctions, including the first period of US sanctions, EU sanctions, UN sanctions, and the second period of US sanctions. The findings show that US-era sanctions and EU sanctions have had less of an impact on Iran's oil exports, but UN sanctions have had a significant impact on these oil exports and Iran's share of OPEC exports. According to research findings, other OPEC member countries have not had a significant impact on the replacement of the Iranian oil market, and this shortage has been mainly met by countries outside the OPEC.

Energy has always played a very important role in human life and is one of the factors that can make economic growth possible. Today, many countries are struggling to invest in new technologies by using renewable energy sources such as solar energy, wind energy, or water energy as their needed sources of energy, which, as compared to fossil fuels, generate lower environmental pollution. The purpose of this study was to evaluate the economic growth of the selected countries of the MENA region from renewable energy sources using the Panel Vector Autoregressive Model in the period of 1990-2015. The results of the study showed that the variable of the total energy produced from renewable sources has the largest share in explaining the changes in the economic growth of the countries under study and its explanatory value reaches 56% in the long run. Given the significant impact of renewable energy consumption on economic growth, suitable policies for renewable energy are needed to achieve a high level of production and social welfare. In this regard, granting financial incentives, establishing a fund for renewable energy by the government, and creating conditions for developing the renewable energy industry in the country could be solutions

This research conducts a quantitative comparative analysis of the dynamic international crude oil trade network of Iran by using the network connectedness measures of Diebold and Yilmaz (2015) and also the asymmetric short-term and long-term impact of the increasing and decreasing key driving factors and obstacles in the crude oil trade development through the gravityrelation and by using the nonlinear panel auto-regressive distributed lag (ARDL) model during 1980–2017. Results indicated the dynamic spillover flow of the crude oil trade of Iran during the investigated period of time. Moreover, the crude oil trade flow of Iran is a net shock transmitter to Middle East and a net shock receiver from the crude oil trade flow in countries of America, Eastern Europe- Eurasia, Africa, Western Europe, and Asia Pacific, respectively. The focus on the divided regional trade scheme and adopting the biased foreign trade policies by Iran may not lead to the vulnerability reduction of its economy from crude oil trade flow volatilities. Findings also reveal the asymmetric behavior of the crude oil bilateral trade flow in response to the increasing and decreasing of gross domestic product (GDP) per capita variables in both crude oil exporting and importing countries and international crude oil transportation costs in the short-term and long-term period that it can be used in identifying the effective factors on the volatility transmission to adjust the crude oil trade flow. Therefore, concerning the high degree of the integration in the international crude oil trade network of Iran, it seems that it is necessary to prioritize cooperative over competitive behavior in the crude oil trade of Iran and respond appropriately to market shocks and volatilities during the time (risk management) in the economic plan of the country.

In this paper, the Panel SVAR model has been utilized on monthly data (2006-2018) to study and compare the direct and indirect effects of oil shocks on real price changes of selected agricultural products in oil exporting and importing countries. The results show that oil shocks, besides direct effect, indirectly affect the prices through aggregate demand, currency and monetary shocks. The response of selected products to different types of shocks in two panels, depends on their degree of substitution to fossil fuels. As the soybeans and to some extent corn price changes, which are most used in the production of biofuels, vary by direction and pattern in two panels, while the price dynamics of wheat is similar. The share of currency shocks and interest rates in explaining price changes in importing countries is higher than the exporting countries, which the main cause can be traced to the more developed financial markets in importing ones. Also, the difference in price response to idiosyncratic and common currency shock in two panels indicates the necessity to study the behavior of each panel member separately. Therefore, a separate model for Iranian economy was also estimated for the purpose of more precise conclusions and policy proposals.

The global growth in energy consumption especially in fossil fuels together with environmental considerations has produced a prospect of considerable increase in the demand for natural gas. The particular conditions prevailing the Iranian gas industry such as the existence of the World largest gas reservoir, the excellent geopolitical location, the access to the free seas and the availability of necessary infrastructures for pipelines as well as natural gas storage offers actual and potential advantages towards this objective, accordingly by benefiting these advantages, we can define the objectives and formulating appropriate actions towards promoting regional and global gas trade, perform an active role in the gas market. The realization of this objective may contribute towards advancing the international status of Iran in political and economic relations.For study the aforementioned topics, the feasibility study of establishing gas-trading hub in Iran is carried out with using SWOT approach. By focusing on the strengths, weaknesses, opportunities and threats in the Iranian gas industry, these points are examined within the SWOT matrix. Finally, the best strategies involving SO, WO, ST and WT strategies are analyzed regarding the transformation of Iranian gas industry into gas-trading hub in the region. The results show that the establishment of gas-trading hub in Iran is possible, although the domestic shortcomings and the international threats, the possibility of achieving this objective in the foreseeable future is rather weak.

This paper examines the response of the natural gas price to the crude oil price in regional markets.The price of natural gas varies in regional markets, mostly follow the crude oil price. Natural gas and crude oil are substitute in consumption and also complement in production. Economic variables such as the crude oil and natural gas prices have inflammations and severe fluctuations over time that conventional linear regressions do not fit these fluctuations. The regime Switching Model provides a flexible and dynamic framework for nonlinear models and sudden reciprocal transfers. In this paper, by using the Markov switching model framework, the impact of the crude oil price on natural gas price has been measured during the period of the January 1992 to June 2017. The results show that in some regimes the price of crude oil has a direct effect on the price of natural gas and in some other ones has a reversible effect. In Europe, the first lag of crude oil price has a reverse effect for 1 month, and 18 months of direct effect, and the second lag of oil price in both regimes has a direct effect on the natural gas price. However for Asia in both regimes, the impact of oil price on natural gas price is straight and the prices are in the first regime for 28 months and 26 months under the second regime.

The main purpose of this study is to evaluate general strategies of the national document of Iran's energy strategy according to World Energy Council scenarios and based on robust strategy framework, to doing so, a standard political framework and its requirements was introduced and then surveyed to realize which strategies are robust to apply the mentioned political framework in the world depicted by each scenario. In compare to standard political framework in National Energy Strategy Document, no suggestion on energy sources diversification and new energies is proposed and no strategy is seen in the field of energy industry safety and to reduce the political and economic risks of investors. Eventually based on robust strategy, we only have two robust strategy in research and development context. But, in other seven political domain no robust strategy is observed, especially in Hard Rock Scenario, no strategy was seen in five axis from eight axis of main political context. Thus, it is advised to review the existing strategies according to opportunities and threats available in any scenario, and to formulate a comprehensive pattern for national energy policy accordingly. In this regards, it seems very important to design a mechanism to develop new energies, to reduce the political and economic risks for oil companies, to create a surveillance and evaluation system for national energy data, to provide a legal mechanism for negotiation, and finally to select an administrator capable to aggregate resources to implement the strategies in the best way possible

The rapid development of gas distribution in Iran causes considerable dependence of consuming sectors on Natural Gas production .The share of South Pars Gas Field from the entire gas production in the end of sixth Five-Year Iranian Economic Plan will be over 62%. The pressure of reservoir gradually reduces and subsequently the volume of gas production declines in the production period due to the natural technical condition of South Pars reservoir. Installation of gas compressor platform is necessary in order to delay the reduction of the production. In spite of installation of these platforms,unofficial announcements indicate that production from South Pars field will decrease significantly in the twenty–year prospect and supply of new gas fields cannot compensate this reduction. Hence, in order to prevent gas shortage crisis in the coming years, it is required to predict some strategic actions and prioritize the supply of gas for new demand sectors. The "AHP" model has been applied to determine the priorities for this purpose. The relevant calculations have been carried out for solving the model by selecting a total of 8 options and 6 criteria by using the Expert Choice Software. The priorities of this study for each option are as follows respectively: Injection into Oil Reservoirs, Gas supply to Power Plants, Export, Feedstock for Petrochemical Units, Gas supply to Industries, Gas supply to Residential& Commercial , Transportation
