One of the effective factors influencing the interaction of individuals with the environment is ecological attitudes which have a key role in forming and changing environmental behaviors. Due to the increasing consumption of energy resources in Iran, the intensive need for energy, the limits of resources, and other environmental problems, it is really needed to study the impact of ecological attitudes on environmental behaviors, especially those in the field of optimal energy consumption. Therefore, the main question of the article is: what effects do ecological attitudes have on the realization of optimal energy consumption behavior? To do this, the present paper is based on the paradigm of the ecological attitudes of Dunlap, Catton, and Van Liere. Research data was collected using a questionnaire and a statistical sample of 440 residents of Sanandaj City by cluster sampling. Questionnaire validity was assessed using the factor analysis technique and KMO calculation and its reliability was assessed by calculating Cronbach's alpha. The main hypothesis is confirmed that there is a significant relationship between ecological attitudes and energy consumption behaviors. In other words, in forming and changing behaviors directed to the consumption of energy, ecological attitudes are very influential. The findings also show that ecological attitudes have great importance among the consumers in Sanandaj City. This importance implies that these consumers devote enough space to environmental behaviors in their socio-cultural lifestyles and are aware that life has an important part to do with the environment.

A major factor in the Iranian stock market is the risk-taking of the economy. The stock index falls when the economy is at higher risk, either by protests or the possibility of war. The present study was conducted to investigate the existence of fluctuations in the currency, stock, gold, and oil markets during the period 2017-2021 using the common t-test and the DCC-GARCH approach. The statistical population includes all companies listed in the Tehran Stock Exchange during the period 2017 to the end of 2021. The period was chosen due to significant fluctuations in exchange rates, coins, oil, and stocks. To achieve the purpose of the study, first, a descriptive study of coin price trends, exchange rates, and stock and oil indices in the Iranian economy was presented and then the conditional correlation between the returns of these assets was estimated using the dynamic DCC-GARCH conditional correlation method. Conditional correlation between currency and stock markets as well as coins and stock exchanges has increased significantly from a period of calm to a period of turmoil. These results are consistent with the results of the transfer test using t-test statistics. The results showed the existence of transitions between the markets and transitions between the foreign exchange and gold markets. The results also showed that the oil market, because it is the most important source of Iran's income, has a major impact on the gold, currency, and stock markets.

Making long-term investments in the oil and gas industry to maintain the current production levels and increase its capacity is one of the ways to increase economic resilience in the country's upstream documents, including the resistance economy's general policies. In recent years, there have been intense sanctions on the country, especially in the energy field. The importance of proper use of China's allocated credit lines to finance these projects is revealed due to the high need for investment in oil and gas industry projects and the impossibility of covering the investment needs of this industry from domestic sources, and the challenge in effective communication with international monetary and financial institutions. Anyway, the conducted studies indicate serious challenges in using the capacity of these credit lines. For this purpose, this research tries to investigate these challenges from many aspects. After studying the background of the research and reviewing various sources, this article conducted targeted interviews with financing experts. Also, the challenges of using credit lines were extracted and classified into four categories: financial and economic, executive and operational, structural and institutional, and juridical and legal, utilizing the method of thematic analysis and focus group. The extracted challenges were exposed to experts to validate the findings. Finally, the formation of the focus group presented the corrective solutions for the use of credit lines to finance oil and gas industry projects.

Energy is one of the essential inputs in production that due to inefficient and inappropriate use of its resources, its consumption has increased significantly. In this regard, the identification of factors affecting energy consumption in the provinces is important. This study aims to investigate the effect of urbanization on energy consumption in Iranian provinces. To do so, we used the STIRPAT model to design the econometric model. The spatial error econometric model in panel data was used to estimate the effect of urbanization on energy consumption in 28 Iranian provinces from 2002 to 2015. The results show that the relationship between urbanization and energy consumption is inverted U-shaped. This finding indicates that an increase in urbanization first causes to increase and then decreases energy consumption.

Improving energy efficiency as one of the most important tools for managing energy demand leads to a phenomenon called Rebound Effect, which causes the energy savings achieved by improving energy efficiency not equal to the expected level. In this study, with employing Input-Output approach and the structural decomposition analysis, we quantify the changes of electricity, natural gas and oil products consumption according to the final demand variations and technological progress in terms of changes in energy efficiency and intermediate demand during the period of 2001-2011. After examination of the economic sectors in which they experience improving energy efficiency, the rebound effect of the energy consumption for each energy carriers has been measured. The results of this study show that electricity, natural gas and oil products from 24 economic sectors in 11, 4, and 20 economic sectors have experienced improvements in energy efficiency due to technological advances. "Construction of basic metals", "Electricity" and "Manufacturing of non-metallic mineral products" have the highest reduction in energy consumption associated with these carriers respectively, and the "postal and support services" 62.83%, "Construction of coke and products from oil refining and nuclear fuel" with 147.72%, "Construction of chemical and chemical products" with 86.33% have the highest efficiency in electricity consumption, Natural gas and oil products. Considering inter-sectional and intra-intermediate interchanges, the rebound effects is increased in all sectors.

The main purpose of this study is to investigate the migration of bubbles from the oil market to the stock exchange. First, using the method of Phillips et al. (2015), bubbles were discovered and dated in the Iranian heavy oil market in the monthly period 1980-2020 and the Tehran Stock Exchange in the period 2008-2020. Then, using the method presented by Gomez-Gonzales et al. (2018), the migration of bubbles from the oil market to the Tehran Stock Exchange in the period 2020-2008 was investigated. The results showed that Iranian heavy oil has 9 bubble cycles in the period under study. Also, six bubbles were observed in the period under review for the Tehran Stock Exchange. The findings indicate the closeness of the ninth bubble in the oil market and the fourth bubble in the Tehran Stock Exchange. The hypothesis of bubble migration from the oil market to the Tehran Stock Exchange was tested in this period. The results of the hypothesis test indicate the acceptance of bubble migration from the oil market to the Tehran Stock Exchange.

Today, in most countries, especially developing countries, economic growth is at the heart of planning. Since the place of economic activity is the environment, unfortunately, growth has had unfortunate consequences for the human environment. The main objective of this study is to measure the reduction of environmental pollutants and greenhouse gas emissions under policy-making scenarios compared to the reference scenario. The research method in this study is using the scenario analysis method based on Long Term Alternatives Planning Model (LEAP). The research findings show that by designing demand-side and supply-side management scenarios, meaning that replacing renewable energies and electricity in place of fossil fuels (crude oil and natural gas), reducing the amount of environmental pollutant emissions for the year 1420 (year horizon) 2014 (Year Zero Planning) is 123.5 million tonnes.

The impact of technological advances on energy consumption is one of the topics that has been considered by many researchers and policymakers. Numerous researchers have tried to evaluate this relationship based on various technology indicators. The index of economic complexity is one of the new indicators that has been used in recent years to measure the level of knowledge and technology in the production structure. In this paper, the index of economic complexity along with energy prices and GDP have been used as determining factors of energy consumption in Iran during the period 1976 to 2018. Quantile regression results show that the coefficients of the variables are different in the deciles. The impact of economic complexity on energy consumption in all deciles has been positive, indicating the dominance of the rebound effect on energy consumption. Price elasticity is less than one in all deciles and less in the higher consumption deciles. In contrast, the income elasticity of energy demand was higher in the upper deciles

This study examines the correlation and causal relationship between energy carriers' consumption and Iran’s provinces' gross product for the period 1988-2017 using wavelet analysis with panel data and the Dumitrescu-Hurlin causality test. The results of correlation analysis show that the correlation pattern between energy consumption and GDP, in different energy carriers, is different. The correlation between natural gas, gasoline, kerosene, and electricity with GDP is strong at all energy intensity levels. The correlation between furnace oil and GDP is reported to be low and weak for all provinces in the long run. Furthermore, the findings show that in provinces with high energy consumption intensity, consumption of gasoline, fuel oil and total energy have led to GDP in the short run. In high-intensity cases, consumption of kerosene, gas oil, fuel oil and natural gas, in medium intensity all types of energy, and in low intensity, consumption of kerosene, furnace oil and gasoline have led to GDP. In provinces with very low energy consumption, energy carriers' consumption has not led to GDP while in the medium and long term, the feedback hypothesis is proven

Today, energy supply is one of the most important axes of the strategy of different countries due to its vital role in the continuation of technological and economic development of countries. The Petroleum industry, as one of the most important industries producing energy, has become an important and special industry due to the complexities of its production and extraction. Therefore, classification and prioritization of changes have taken place, and presenting a model of how to deal with changes can play an important and fundamental role in managing changes in executive projects. Of course, no project can completely eliminate the risk of change, but it can be largely prevented by identifying the underlying causes of change.
In this study, an attempt has been made to compile a study and present a questionnaire and interview with experts and specialists in the oil industry, information, and existing records, which resulted in finding 20 of the most effective changes in EPC projects in the field of the petroleum industry. For this purpose, after reviewing and analyzing the changes, the model of dealing with the changes in EPC projects is presented and then according to the main parts of EPC projects, the most effective cases of each part are determined by using multi-criteria decision-making methods consisting of series. Analysis Hierarchy Process (AHP) and Gray Relationship Analysis (GRA) have been proposed to provide a change management structure in EPC projects in the oil industry. Based on the obtained results, it was found that the design and engineering (E) phase has the greatest impact on the changes made in EPC projects, followed by the manufacturing and construction (C) and procurement (P) phases. This research could be useful for prioritizing and managing change and minimizing the impact of unintended changes on EPC projects in the petroleum industry

Due to the problems and limitations of using fossil energy sources, the use of biofuels in order to achieve the goals of sustainable development, reducing greenhouse gas emissions, regional development, and security of energy supply, has received more attention. Therefore, considering the importance of the issue, in the present study, while determining the effective factors on the tendency of farmers to accept the supply of crop residues of wheat and barley products for bioenergy production, the economic value of residues of selected products in biogas and bioethanol energy production is estimated. Accordingly, using a survey approach and by completing a questionnaire by farmers in Boroujerd in 1399, data collection and research hypotheses were tested using the logit regression model. The results of the study indicate that the variables of collection cost (with a final effect of -0.097 and elasticity of -7.39%), non-agricultural income (with a final effect of -0.028 and elasticity of -6.37%), and use from residues (with a final effect of -0.014 and a tensile strength of -11.6%) have a negative effect on the supply of agricultural residues for bioenergy production. Meanwhile, education (with a final effect of 0.09 and elasticity of 4.4%) and farmer experience (with a final effect of 0.022 and elasticity of 17.32%) have a positive effect on the supply of agricultural residues for bioenergy production. According to the results of traction, farmers' experience and farmers' use of agricultural residues have the greatest effect on the supply of agricultural residues in bioenergy production. The results also show that the annual production potential of bioethanol from wheat and barley residues is equal to 63.96 million liters. So that if the same residues are used in biogas production, the annual biogas production potential is equal to 88.98 million cubic meters. Accordingly, the economic value of bioethanol and biogas energy production from wheat and barley residues in the study area has been calculated equal to 15349 and 430 billion rials, respectively. Therefore, based on the results, by planning for the principled management of agricultural residues and investing in the use of biomass as clean sources for bioenergy production, effective measures can be taken to reduce the dependence of the country's economy on fossil energy and provide the energy needs of people in remote areas.

The objective of this study is to investigate policy shocks to the ecological footprints of 33 oil-exporting countries for the period 1961-2017. For this purpose, we apply the panel stationarity tests with both sharp and smooth breaks developed by Bahmani-Oskooee et al. (2014) and Carrion-i-Silvestre et al. (2005) to test the persistence of shocks on environmental degradation. The overall results suggest that shocks to the ecological footprint as an indicator of environmental degradation in oil-exporting countries have temporary effects. In other words, the ecological footprint under the two assumptions of long-term homogeneous variance and long-term heterogeneous variance has a mean-reverting behavior. The results of the univariate test also reveal that the ecological footprint is stationary at a 10% significance level for all oil-exporting countries except Canada, Congo, Egypt, Indonesia, and Iran. This implies that policymakers should design effective long-run policies to reduce the ecological footprint in these countries.

Investigating the relationship between oil revenues and financialization in countries with abundant natural resources is particularly important. Considering the dependence of Iran's economy on oil rent, this paper examines the effect of oil revenues on financialization. The simultaneous equations system approach and time series data for 1979 through 2018 were used to analyze the relationship between variables. The research findings show that oil revenues positively and significantly affect financialization. Also, economic growth, human capital, and institutional quality have a negative and significant impact on financialization. But, physical capital and inflation impress positive and significant effects on financialization. Therefore, oil revenues along with the low quality of institutions, extensive sanctions, and oil price fluctuations conduct in an increase in rents and corruption, weakening of property rights, distrust of government policies, and an increase in speculative incentives. A rise in speculative incentives leads to the deviation of capital from the real to the financial sector; finally, the capital transfer to the financial sector also directs to an increase in financialization.

The main purpose of this study was to investigate the role of trade by export and import of intermediate and final goods on environmental degradation, and carbon dioxide emission, in the form of the Environmental Kuznets Curve (EKC). For this purpose, a panel data set of OECD, and non-OECD countries from 1998 to 2018 was used. According to the results, the EKC was established in all samples. In addition, while with a sample of OECD countries, trade has a beneficial or inverse effect on carbon dioxide emissions; with a sample of non-OECD countries, and that of all countries, a non-beneficial or direct effect from trade on carbon dioxide emissions prevails. Also, an important conclusion is that imports, regardless of the type of goods, had a more destructive effect on the environment than exports in all samples. Therefore, theories supporting beneficial effects of exports, e.g. improving technology, or destructive effects of imports through energy-intensive products, are better explanations of the issue than theories of destructive consumption of energy resulting from exports, or beneficial effects of imports for the environment

Despite the decrease in the share of oil in the world's energy basket, the absolute amount of oil consumption is still increasing. Oil is at the center of the economic and political developments and countries with the oil and gas deposits are trying to maximize their benefit from these reserves. In Iran, there have been many policies and legislations related to optimizing the value and volume of the oil and gas reserve. The term "conservation production" has been mentioned several times in several legislations and guidelines however, it is still ambiguous as to how to implement this framework. This research has sought to use the real data of an oil reservoir (with periods of natural depletion, primary production, secondary and tertiary recovery), different objective functions (reservoir net present value and final recovery factor), and the effect of changes in the optimization period to model the concept of conservation production. The results show that the changes in the objective function and the optimization periods would have a significant effect on the production path.

Today, the issue of significant increases in polluting gases has become a major global challenge. This issue, along with industrial growth and development in developed and developing societies, has attracted more attention in order to prevent their destructive effects. The purpose of this article is to investigate the factors affecting the spread of pollution in the petrochemical sector. In order to test the relationship between the variables, a mild transfer regression model for the period 1399-1396 has been used. The statistical population of the present study is companies producing petrochemical products. The most important variables used in this study include per capita carbon dioxide emissions, product output, energy intensity, technology costs, and added value of petrochemical products. The results showed that there is a nonlinear relationship between the variables of production and pollution. In the estimated nonlinear model section, because the energy intensity variable has been selected as a variable, it was observed that with increasing the intensity of energy consumption from 5.12%, the effect of petrochemical production on the level of emissions is different and significant. The results obtained from the nonlinear model estimate show that the production of petrochemical products in companies producing petrochemical products at different levels of energy consumption has different effects on carbon dioxide emissions in the country. Accordingly, given that greenhouse gas pollution is one of the serious threats facing countries, and due to its nature, factories and companies producing petrochemical products should be required to reduce emissions through tax and incentive policies. In addition, more polluting industries and polluting products should be prevented from entering the production process through strict environmental laws and regulations, especially in the petrochemical sector..

During the last decade, the international price of crude oil has experienced frequent periods of volatility; which has motivated researchers to investigate how oil price uncertainty affects economic activities and financial markets. Reasonably, oil, as a direct or indirect input factor, can strongly affect the cost of production and profitability expectations of companies. Accordingly, oil price changes can change the company's decision-making and performance. In this regard, we have investigated in the present research the impact of crude oil price volatility on the leverage criteria of companies admitted to the Tehran Stock Exchange. For this purpose, we have used the data of 160 selected companies during the period of 2011 to 2019. We used the panel data method in order to analyze the collected data. The findings of the research showed that crude oil price volatility had negative and significant effects on the leverage criteria of listed companies. Therefore, we concluded that companies reduce their demand for financing to overcome the uncertainty of oil prices. Consequently, an increase in uncertainty in oil prices can motivate companies to reduce their demand for external financing and thus reduce their leverage.

The price of crude oil is one of the most important indicators of the global economy, which is monitored by policymakers, producers, consumers, and participants in financial markets. Oil prices are changing course depending on economic conditions, which is why it is so volatile. The knowledge of researchers, policymakers, and stakeholders about the impact of crises on the oil market provides better control over its negative consequences. Studies show that as a result of various crises, the Volatility Persistence of the oil market is very high. Therefore, it makes sense to consider the hypothesis of a unit root in the Volatility shocks of this market. In the present study, the long-term Volatility Persistence shocks due to the Covid-19 epidemic crisis in the Brent and WTI oil markets, which are the two criteria for determining global oil prices, are investigated using a test proposed by Lee and Yu (2010). The results of this study indicate the existence of a unit root in oil market turbulence. Therefore, the oil market and the economic climate are long-term affected by the effects of this crisis. This can have a significant impact on the revenues of exporting countries and investors in the crude oil sector. Thus, market players and governments need to assess the consequences of this crisis more carefully

The equality implications of tariff design for household gas and electricity, two essential substitutes, present a significant concern for policymakers. In this study, we examine this issue using a sample of household income quartiles across various social groups, exploring the diverse effects of changes in electricity and gas prices. The findings reveal that an increase in gas prices exerts a more pronounced impact on low-income groups compared to an equivalent increase in electricity prices. Our partial analysis indicates that gas exhibits less elasticity, likely attributed to the absence of a suitable substitute in the event of a price increase for this commodity. This observation underscores the lack of energy diversity that is rooted in the critical role of gas appliances in cooking and heating. This phenomenon poses a potential threat to the energy security of Iranian households.

The increasing population and rising demand for water and energy supply, along with the exacerbation of environmental pollution effects on natural and human resources, demonstrate the vital need for a cohesive movement toward the water, energy, and environment Nexus (WEEN). Since the electricity generation industry has a significant share in water and fuel consumption and CO2 emissions in Iran, in this study, the application of a combined renewable system in the Zarand Steam Power Plant was evaluated based on the Nexus approach. Solar system designing and carbon balance evaluation during plant lifetime was conducted via PVSyst software in 2021. Also, an environmental model of ReCipe was applied to evaluate the effect of carbon reduction on the ecosystem. The results have shown that replacement of at least 1% of the nominal capacity of the fossil power plant with renewable sources, will significantly prevent 1249/46 t CO2 emission annually in this power plant which is equivalent to 362/160 m3 fossil resources storage and 373/73 TOE.year-1 energy savings. Also, the results showed that in addition to protecting valuable natural resources, the combined cycle will lead to a significant reduction in water demand equivalent to 3660 m3 having the capacity of supplying underground water resources. Considering the benefits of saving water and energy resources and reducing carbon emissions, from the NEXUS approach, in addition to managing energy supply through replacing resources and using water and heat recovery technologies, applying energy demand management policies based on energy efficiency and its environmental effects is suggested..

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.

Crude oil is the main source of energy and accounts for about a third of world energy production. Turmoil in this market will have far-reaching economic and financial consequences. Because of this, investors attach great importance to predicting volatility when investing in crude oil markets to hedge risk and portfolio diversification. However, their investment strategies are often strongly influenced by volatility because, in different periods of crude oil markets, there are high and low fluctuations that are attributed to the movement of economic cycles. Accordingly, the present study compares the Markov Regime Switching (MRS) and Hidden Markov (HM) volatility models with the GJR-GARCH asymmetric model on their forecasting capabilities in the WTI and Brent crude oil markets. Empirical results show that the MRS-GJRGARCH model performs better than the HM_GJRGARCH model in predicting volatility in both markets. Accordingly, using the two criteria of value at risk and the expected deficit, the minimum loss and the expected loss for December 2021 were predicted. The results show that the expected shortfall from investing in the WTI market is greater than the Brent oil market

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.

Regarding the role of the energy market, especially oil, on the economy of countries, it is important to identify the future evolution of the market. In this respect, predicting the changeable extreme evolution of the oil price is crucial for decision and policy makers. This study attempts to investigate the maximum changes of OPEC’s oil price by employing the concept of Value at Risk. To this end, GARCH family models based on the normal and extreme distribution were used, and it is expected that the focus on the latter in forecasting Value at Risk, especially in the face of extreme events, may end up in more realistic results. The results of the backtesting of models show that the ARMA-GARCH-EVT model predicts better than the other ones.

Oil and natural gas production is not uniformly and homogeneously distributed across all provinces of Iran, whereas a major part of oil and gas incomes is consumed in provinces that do not have any significant role in oil and gas production. Therefore, any disruption in the production of oil and gas might expose the GDP growth of all provinces at risk. In this paper, the multiregional input-output table is calculated for the year 2015. Then, the hypothetical extraction method introduced by Dietzenbacher and Lahr (2013) is employed for estimating the effect of partial and complete extraction of oil and gas production in Khuzestan and other oil-oriented regions on the value-added of 71 economic activities in each of the regions. The findings reveal that firstly, following the extraction of oil and gas production in Khuzestan, the value added of this region reduces about %32 , while the extraction of the corresponding sector in other oil-related regions will mitigate this region’s value added by %14. Secondly, the relative reduction in the value added of economic sectors and each sector’s contribution of value-added reduction in each region depend on the economic structure of the interested region. The highest share of the total value-added reduction in each region belongs to the service sector in Tehran and agriculture in other non-oil regions. It seems that diversifying energy resources as well as supplying regions, enhancing fuel consumption efficiency, and renovating the transportation system are the most important policies to have more resilience.
