摘要：This article calculates, presents and discusses on sectoral and spatial multipliers in the USA economy using 6-country-30 sector input-output tables for the year 2000, 2005, 2010 and 2014. The results revealed that firstly, all sectors with total output multipliers more than 2; flow-on effect was more than initial effect. In the USA economy, there were 19 sectors in the year of 2000, 18 sectors in 2005, 2010 and 2014, with total output multipliers more than 2. Secondly, total output multipliers had negative correlation with percentage of multipliers that occurred in own-sector. The higher total output multipliers, the smaller percentage of multipliers occurred in own-sector. All initial effects occurred in own-sector. Parts of direct effects occurred in own-sector and parts occurred in other-sectors. All indirect effect occurred in other-sector. Thirdly, total output multipliers had negative correlation with percentage of multipliers that occurred in own-country. The higher total output multipliers, the smaller percentage of multipliers occurred in own-country. All initial and direct effects occurred in own-country. Parts of indirect effects occurred in other-countries.
