Analysis of Output Multipliers,spillover,feedback effects and Identify leading sectors in the two-region input-output table (case study: oil-rich regions of Iran and the rest national economy)

One way to achieve economic growth is to invest in leading sectors. In addition, economic sectors can stimulate economic growth in other regions through the effects of spillover and feedback on their output. The purpose of this study is to identify the leading sectors, the effects of spillover and feedback on Oil-rich region. For this purpose, the two-region input-output table of Iranchr('39')s oil-rich regions and the rest national economy are used. The results of the research show that in the oil-rich regions, from the demand side, the highest Output Multipliers is devoted to the production of rubber, plastics and petrochemicals. From the supply side, the sectors of wood and paper manufacturing, distribution of natural gas, manufacturing of metals and other mines have the highest Output Multipliers. And the average of spillover effects of oil-regions is 0.09 and other national economy is 0.05 due to the larger The rest national economy. The results show that agriculture, metal construction and transportation, warehousing and communications are leading Sector in oil-rich areas and The rest national economy. The petrochemical sector is only a leading Sector in oil-rich areas, however crude oil and natural gas are not leading Sector in either region. Therefore, expansion of downstream industries of crude oil and natural gas in oil-rich areas is recommended.
