Decomposition and Determinants of Energy Intensity (Case Study: Transportation in Iran)

Decomposition method one of the most popular methods to study for changes to energy consumption that it changes the energy consumption divided to three effect contains productive effect, intensity effect and structural effect. The results of decomposition of energy consumption in the transport sector in Iran shows productive effect, intensity effect and structural effect, to arrange the most important role in explaining the changes in energy consumption in this sector. Estimation of energy intensity model in the transport sector to SVAR method showed that in the short term the energy intensity, energy consumption, energy prices, capital formation, labor force and value added, most contributions described in energy intensity and in the long-term energy prices, value-added, labor force, energy consumption, energy intensity and capital formation most contributions described in energy intensity. In the short term energy intensity with energy intensity, value added, capital formation, labor force and energy prices positively and negatively associated with energy consumption. In the long term, energy intensity with energy intensity has a positive relationship and with the variables energy consumption, value added, capital formation, labor force and energy prices is negative.
