Energy is always a widely used input in the production sector and used in the distribution and consumption of many goods and services, which should be used optimally. One of the indicators showing the optimal use of energy input is the energy intensity index. Obviously, the lower the energy intensity, it means that less energy has been used for each unit of production of goods and services. Several factors can be mentioned that affect energy intensity, of which innovation is one of the key ones. Therefore, the purpose of this article is to investigate the influence of several factors on energy intensity in selected countries of the MENA region during the period of 2010-2020, with an emphasis on innovation and its two sub-indices (Information and communication technology and Access to finance). To achieve the goal of the research, the panel data model (panel data) for 13 selected MENA countries and the GMM estimation method have been used. The results show that the influence of control variables including "government final consumption expenditure", "energy price" and "trade openness" on energy intensity is negative and significant. The estimation findings of the first model indicate a negative and significant effect of the overall innovation index on energy intensity, and the estimation results of the second and third models also indicate a negative and significant effect of the innovation sub-indices (information and communication technology and financial access) on the energy intensity of the selected countries in the period. is under investigation.

Many studies have shown that economic conditions affect energy intensity.As a fundamental component of macroeconomics, business cycles are a fundamental factor in energy intensity.The present study examines the asymmetric effect of business cycles on energy intensity in Iran in the period 1972-2020. In order to analyze the relationships between the variables, Nonlinear Autoregressive Distributed Lag (NARDL)was used.The results of the model show that in the short term, the impact of the negative impulse of the business cycle on the energy intensity has a negative effect until the first break and then a positive effect until the third break, while it is positive in the long term. But the positive impulse to the business cycle in the short and long term has a negative effect on energy intensity. Also the results show that the coefficients related to the logarithm variable of OPEC oil price in the short and long term are positive. But the short-term and long-term coefficients of the logarithm of the industrial structure index show that energy intensity decreases by 0.12%and increases by 0.04%in the short-term and long-term, respectively.Finally the results of Wald's test show that the effects of positive and negative impulses of business cycles on the energy intensity index are asymmetric in the longterm,but in the short term, this effect is symmetrical.Recognizing business cycles can lead to correct decision-making by policy makers in the development of the energy industry and at the same time, it can effectively prevent and even reduce the excessive growth of energy intensity

The main goal of the research is to investigate the impact of various factors on energy intensity with emphasis on economic complexity and mutual relationship between financial risk and financial development. The statistical data used in this research are from the International Country Risk Guide (ICRG), World Bank, energy balance and MIT University website during the years 2000-2022. In order to estimate the target model, the Auto Regressive distributed Lags approach (ARDL approach) has been used in the framework of short-term dynamic model, long-term relationships and error correction model. ARDL model (1,0,0,0,0,0,0,0,0,0,0) was selected with one interval for energy intensity variable and zero interval for all independent variables based on Schwartz-Bayesian criterion. The results of the ARDL dynamic model in the short-term and long-term show: the effect of energy price and capital per capita on energy intensity is indirect. The effect of variables of economic complexity, trade liberalization, urbanization rate and internet users on energy intensity in the short and long term is direct. Despite its statistical significance, the coefficients of domestic investment and labor force are very small and close to zero. The mutual effects of financial risk and financial development, as well as the foreign direct investment variable, did not have a significant effect on energy intensity in both time periods.

Corruption and political risk are important factors affecting the economies that can affect various aspects of people's lives. On the other hand, one of the important economic indicators that shows the intensity of energy consumption, and in other words, the amount of energy consumption in each country, is the energy intensity. Energy intensity is a crucial indicator by which we can understand the trend of changing energy efficiency in different years. Given the importance of this issue, the present study examines the effect of corruption and political risk along with other factors on the energy intensity of selected countries in the Mena region, including Iran, Bahrain, Egypt, Iraq, Jordan, Kuwait, Lebanon, Qatar, Saudi Arabia, and UAE using by a panel data model for 2003 to 2019. The results show that corruption, political risk, and factors such as good governance, foreign investment, and human development are important. Therefore, improving education and awareness by reducing corruption and political risk can lead to better implementation of energy efficiency programs.

GDP is one of the factors affecting energy consumption and climate change. This study examines the impact of GDP on energy consumption in OPEC countries in two stages. In the first stage, based on the panel causality test, the causal relationship between GDP and energy consumption was investigated, and the results indicate a one-way causal relationship from GDP to energy consumption. In the second stage, using a dynamic panel threshold regression model, this study investigated the role of energy intensity (one of the important indicators of energy efficiency) in the relationship between energy consumption and the GDP of OPEC countries. The results showed that at values above the threshold level of energy intensity (7.27), GDP significantly increases energy consumption, while at values below this level, GDP has a positive and non-significant effect on energy consumption. Without considering the control variables, at values above the threshold level of energy intensity (6.91), GDP significantly increases energy consumption, while at values below this level, GDP has a negative and non-significant effect on energy consumption. In energy and environmental policy-making, paying attention to energy intensity can lead to sustainable economic growth. Also, the results of this study are related to the Kuznets Environmental Curve Hypothesis; at low-intensity energy levels, increased GDP does not necessarily lead to environmental damage.

Energy intensity is an important indicator of energy consumption assessment and its reduction is one of the goals of policymakers and planners in countries. Developing effective policies to reduce energy intensity requires a thorough study of the factors that affect it. In this study, the effect of foreign direct investment on energy intensity convergence by Iranian provinces using spatial econometric technique and panel data of 30 provinces of the country from 2010 to 2015 was studied. After confirming the spatial dependence by Moran and Panel (robust) LM and LM tests, the absolute and conditional convergence of "β" has been tested. According to the results, the absolute convergence of energy intensity in the provinces of Iran was confirmed. This means that the rate of decrease in energy intensity in provinces with higher energy intensity is higher than the rate of decrease in energy intensity in provinces with lower energy intensity. To investigate the conditional convergence, the foreign direct investment variable was added to the model. The results indicate a conditional convergence of energy intensity in the provinces of Iran, as well as a decrease in energy intensity with an increase in foreign direct investment. In fact, foreign direct investment with the introduction of new production technology increases the efficiency of the use of production inputs such as energy, and this leads to the convergence of energy intensity among the provinces of Iran. The effects of the spillovers of foreign direct investment on the convergence of negative and meaningless energy intensity can be attributed to the low level of foreign direct investment attraction and its non-distribution at the provincial level. In general, the increase in foreign direct investment in a particular province causes the convergence of energy intensity and its spillovers effect potentially causes the convergence of energy intensity in the provinces of the country.

The purpose of the present study is to examine two hypotheses implying the importance of the resource rent and the governance quality interactive effect on determining energy intensity. Based on the first hypothesis, the resource rent (governance quality) independently increases (decreases) the energy intensity, while according to the second one, the energy intensity is affected by the interaction of the two mentioned factors and in this line, the final effect of the resource rent and the governance quality on the energy intensity may be strengthened or weakened. These hypotheses have been tested by employing GMM for 58 fuel exporting countries including Iran during the time period 1998-2015. The results confirm the hypotheses and verify the vital role of the governance quality in affecting the rent on the energy intensity. The findings of this paper indicate that the independent impact of the resource rent and the governance quality on the energy intensity is positive and negative, respectively. Furthermore, based on the interactive effect, the positive impact of the resource rent becomes weaker while improving the governance quality. On the other hand, the effect of the governance quality on the energy intensity is negative even in the presence of the resource rent that shows the essential role of this factor in determining of the energy intensity.

Increasing the efficiency of production factors poses as a main part of the overall Iranian resistance economic policies explicitly pointed out at paragraphs 3, 4 and 20. In the meantime, energy efficiency increase has been highly regarded through country's policy makings. Because increasing energy consumption intensity not only leads to waste resources, but also environmental deadlock as well as reduces ecological strength. In this regard, the realization of quantitative and qualitative structure of the knowledge-based economy in the country and the provinces could culminate in energy consumption intensity reduction.
Regarding to cases mentioned above, this study aims to investigate the relationship between selected indicators of knowledge-based economic structure and energy intensity index among provinces of Iran during the period of 2010-2013. Therefore, the econometric models of study stipulated within the framework of panel data and coefficients were estimated by panel GLS estimator. According to the results, variables of Internet penetration rate and intensity of mobile phone subscribers have negatively and positively affected energy intensity index of provinces respectively. Furthermore, intensity of employees with Associate and BA degrees significant and negative affects on energy intensity of provinces. Also, the intensity of employees with Graduate Studies significantly decreases provinces energy intensity but less than the first.

This paper evaluates the threshold effect of income on carbon dioxide emissions intensity in the MENA countries using panel smooth transition regression model. For this purpose, the variables of financial development, openness, energy intensity, income per capital and carbon dioxide emissions intensity over the period 1980 to 2011 are employed. While the results strongly indicated the existence of a nonlinear relationship, considering one transition function and two threshold parameters is sufficient to specification of nonlinear relationship among variables. The empirical results show that the slope parameter in which the speed of adjustment represent from one regime to another one is estimated equivalent of 78762, and two threshold parameters estimated 1176 $ and 11614 $ based on income per capita respectively. The variables of openness and income per capital lead to reduce carbon dioxide emissions intensity in both regimes in which the impact of income per capital in first regime and openness in second regime is greater than another regime. Although, financial development leads to slight increase in carbon dioxide emissions intensity in the first regime, but in the second regime leads to decreases it.

Energy intensity is one of the important and attractive indicators in energy economics. According to the abundance of energy resources in Iran, these resources are not used properly and therefore energy intensity is very high compared to other countries. Hence in this paper using a nonlinear regression method, we study the factors affecting energy intensity in Iran during the period 1979-2013. The results indicate that the existence of two regimes by considering relative price of energy as transition variable with the threshold about 1.58. The rate of urbanization and industrialization had positive effect and the level of technology and relative price of energy had negative effect on energy intensity in Iran. The effectiveness of relative price in the high price regime is intensified and the effectiveness of industrialization and technology is dropped. These results would suggest the important role of price regime on the effectiveness of energy intensity determinants in Iran and leads policy makers to prevent the decrease in the relative price of energy in the years following the implementation of targeted subsidies.

This study aims at analyzing the energy intensity and also the effect of changes in the production technology on the efficiency of energy consumption in Iranian manufacturing sector. To this end, a regression method entitled the Translog Cost Equation Function is used to evaluate the energy consumption. The period of investigation is 1999- 2011. The results show that the energy intensity in the period of investigation is equal to 0.08 percent which indicates the effectiveness of this variable in the industrial sector. Findings also demonstrate that the technology had the lowest effect, while the small change in the price of energy (i.e. substitution and budgetary effects) had the highest effect on the energy intensity. This means that due to the structure of the industrial sector of the Iranian economy and the low price for energy as well as its adequate supply has led to the utilization of energy intensive components.

In spite the global efforts to reduce energy intensity; Iran’s energy intensity has been increasing during the recent decades. To get a more detailed investigation of energy intensity, this study aims at decomposing energy intensity into its components including efficiency and structural change as well as at examining driving forces behind Iran’s energy intensity components during 1973-2011. Energy intensity decomposition showed that efficiency changes accounts for the most of increased energy intensity. It is found in this study that income (GDP), capital- labor ratio and urbanization are the most determinants of energy intensity and its components. Regarding the non-linear relationship between energy intensity and driving forces of income and capital-labor ratio as well as the estimated turning points, income plays a significant role in increase of energy intensity while capital-labor ratio tends to induce a reduction in energy intensity. Although urbanization has a positive contribution to energy intensity via structural changes component, its dominant effect on improved energy efficiency leads to an overall effect of reduced energy intensity by more than 1.8% as 1% increase in urbanization. The results showed a limited effect for price and share of industry in GDP and left no significant role for economic integration and foreign direct investment. The corresponding value for these variables remain less than 0.05%. 1.0pt;line-height:85%;font-family:"B Zar";letter-spacing: -.2pt;mso-bidi-language:FA;mso-ansi-font-style:italic'>کار با شاخص‌های شدت انرژی و نقطه عطف مترتب بر آنها در مجموع اثر درآمد در جهت افزایش شدت انرژی و اثر سرمایه در جهت کاهش شدت انرژی ارزیابی شد. اما شهرنشینی با وجود افزایش شدت انرژی از طریق تغییرات ساختاری از طریق بهبود کارایی در مجموع موجب کاهش شدت انرژی فراتر از 8/1 درصد به ازای 1 درصد افزایش شهرنشینی خواهد شد. اثر قیمت و سهم صنعت از تولید ناخالص داخلی بر شاخص‌های فوق محدود و اثر متغیرهای شاخص ادغام تجاری و سرمایه‌گذاری خارجی قابل اغماض ارزیابی شد. رقم متناظر برای متغیرهای یاد شده بیشتر کمتر از 05/0 درصد به دست آمد.

National Iranian Oil Company as the second largest oil company in the world and the biggest business complex of Iran has an undeniable importance in Iran, and its activities and management have significant impact on economic and political spheres of the country. The issue of reforming the NIOC articles of association has been a matter of discussion for years in the legislative and administration departments. The stated reasons could be the separation of state duties from the company duties, defining company’s scope of work, omission of additional advantages and adjustment with the new upstream legislations. This study is an attempt to answer the question of “what are the features and principles of a desirable NIOC articles of association?” This question is dealt with by analyzing the past NIOC articles of association as well as examining the selected similar articles of association from National Oil Companies world-wide. Based on this analysis, the acts such as concentration of NIOC on company duties and administrative affairs, not being involved in government affairs and subsequently submission of all the responsibilities and authorizations related to conservation, controlling and supervision on upstream activities to The Ministry of Petroleum are suggested to the National Iranian Oil Company. Considering the professional and business essence of NIOC responsibilities, the activities of the company must be performed in a competitive context with no specific exclusive advantage. More specifically, NIOC can succeed in a competitive environment only under the circumstances of facing the risks inherent in its activities.

Due to the need forenergy efficiency inindustrial sector, assessment of thefactors affectingenergy intensity seems as an essential task.Inthis study, using panel data approach, the main factorsaffectingenergy intensityinnine branches of Iran's industry during 1374-1389 period were examined. Results show that both energy price and technology are inversely related to the energy intensity. Meanwhile, the results also indicate that the speed of energy consumption (growth of energy consumption) is less than the speed of growing of value added in industries (growth of production) which in turn is indicative of the fact that bigger scale manufactures are more energy-efficient. Therefore, we recommende the use of bigger scale industies through integrating small scale ones. In addition, energy price adjustment, promotion of technology and inflation rate control, as the permanent policies to decrease energy intensity, could be effective.
