Assessing the Importance of Energy Sector Using the Expanding Extraction Method: Iranian Economy

In this paper, the Expanding extraction method of Dietzenbacher & Lahr (2013) is used and in the form of Input-Output general equilibrium model. The article assesses and evaluates the importance of the energy sector and its sub-sections in the Iranian economy based on Iranian input-output table of 2017 that is updated by RAS approach. In this way, the 10% reduction in the supply of coal, crude oil and natural gas, electricity and gas consumed has been investigated in four scenarios. Additionally, in the fifth scenario, by aggregating energy subsectors into one sector, the 10% reduction in the supply of energy in interaction with 75 sectors is measured. The results of this simulated model show that by reducing the supply of energy sector, "Manufacture of coke and refined petroleum products" will drop by 9% in value. Respectively, "Transport via pipeline" and "Manufacture of chemicals and chemical products" reduced by 4% and 2% in value added
