Intersect oral analysis of the importance of energy sector in Iran: Input–output approach

Energy is one of the most important factors of production in all sectors of any economy. Iran's economy is highly linked to its energy sector, specially oiland gas industries. Since the energy sector has a strong and important links with other sectors, it should be studied thoroughly; for this reason we haveused the input-output approach in this research which consider the all sectors of the economy together. Additionally by linkage analysis (backward andforward linkage) we have specified the importance of energy sector for all sectors and vice versa. Energy sectors in this research are include crude oiland natural gas, natural gas distribution, petroleum productions, and electricity sectors. Our findings indicate that petroleum productions sector with 6.476and 1.937, respectively have a most forward and backward linkage coefficients and crude oil and natural gas sector with 2.018 and 1.060 have aleast coefficients among energy sectors. Natural gas distribution sector with 4.361 and electricity sector with 2.836 after petroleum productions sector havea most forward linkage coefficients but for backward linkage coefficients, electricity sector with 1.395 and natural gas distribution sector with 1.074 are the most important energy sectors. Moreover we have use a normalization forthis coefficients, but the consequence of the results didn’t change with that adjustment.
