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.

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.
