There is no doubt that improving the level of social welfare, meeting the basic needs and achieving to high economic growth rate are the important aims of policy makers. On one hand, coinciding with the year in which codification and approval of 6th development program is on the agenda of parliament and government and on the other hand, lack of financial resources may lead to policy makers have encountered with the issue of identifying key sectors and evaluating importance of economic sectors. In this paper, for the first time we have studied the consequences of 10 percent shutdown in the health sector supply on output and value added of other sectors. For answering this question, we have applied partial extraction method which proposed by Dietzenbacher and Lahr (2013). In addition, we have investigated the dependency of health sector on other economic sectors by means of 10 percent partial extraction of sector’s supplies. Updated domestic Input-Output Tables in 2011 which aggregated in 19 sectors is the basis of calculation. The results show that first; the economy’s total value added was decreased 0,43 percent due to partial extraction (10 percent) of health sector. Second, public and private health sectors in comparison with other subsectors of health are more important because, the total value added of the economy was diminished 0,03 and 0,02 percent because of the reduction in their deliveries. Third, following partial extraction of health sector and its subsectors, the largest decreases in value added take place in the medical instruments, water, electrics and gas, other services and business services while public affairs and education and oil and gas, had the least changes in the value added that reflected low dependency of mentioned sectors on health sector. Fourth, the health sector is most dependent on the manufacturing sector and its value added decreased 0,3 percent by partial extraction on manufacturing sector.

In this research the effect of energy intensity shocks on energy use of three sectors of economy is studied through input-output table and the dependence of every following section on energy section is computed by calculating forward linkage index of energy sector with each following section. The results show that industy sector has most dependence on energy sector and provide 3% of it’s input from energy sector and after that services and agriculture sectors provide 1.3 and 1.2 percent of their input from energy sector. The coefficients of sensitivity and Power of Dispersion Index of energy sector associated with the agricultural sector indicate that the impact of energy sector on the agricultural sector is greater than the influence of this sector from agricultural sector. By calculating energy intensity shock and considering it’s effect on energy use of economy sectors, forward linkage index of energy sector with each sector is increased equally and also their dependence is increased too.

Oil industry is one of the biggest and most influential industries all over the world, especially in Iran. Besides being the main source of energy in today’s world, oil plays an important role in determining a country’s national power and international credibility. The oil sector has provided the majority of income for many years in Iran and in fact, this sector plays the main role in the country’s economy. Also, with regard to the fact that developing countries have limited resources and unlimited needs and cannot develop all the economical sectors at the same time, they should give priority to key sectors. This study attempted to identify the key sectors and scrutinize the oil industry as an important and a key sector in Iran’s economy, through Input-Output table of 1380 (Iran's last Input-Output table) which was aggregated into 34 sectors. The sensitivity of dispersion index and the variance index of the oil industry were 1.027 and 0.17 respectively which indicate that the relationship between this industry and the other sectors is well above the average of whole sectors and this relation is distributed evenly among the other sectors. If the oil industry is removed from the output sum, 119219783 Rials (Leontief model) and 137162804 Rials (ghosh model) would be lost in production. Also, 130618 (Leontief model) and 344108 (ghosh model) job opportunities would be lost. Concerning total output elasticity, the oil industry ranks 4(among 34 sectors) and this shows that this industry is very important and has an increasingly role in total output. But Concerning total employment elasticity, it ranks 23. In addition, the oil industry has the highest costs for job opportunities up to 880721697 Rials.
