Intermediate goods are another produced factor of production, like capital. Considering intermediate goods in production function makes multiplier be even larger than the one. In this paper, based on the approach of Jones (2007,2010) We computed multipliers by intermediate goods. For this purpose, we used Input – Output table of Statistical Center of Iran (base year: 2001). Finding show that 10.6% of total products used in inter- sector transaction and 4.28% used in intera-sector transaction. Therefore, the domestic multiplier is 1.383 and import multiplier is 2.117 and total multiplier is 2.929.These results indicate increase in the multiplier. The industrial sector and mining sector produce the most and the lowest share of domestic intermediate goods, respectively. The highest and lowest shares of imported intermediate goods between economic sectors are in industrial sector and water sector, respectively
