Abstract :

The factors ‘shares are constant in Solow growth accounting approach. The purposes of this paper are evaluating the effect of capital income share change on economic growth, implementing the growth accounting approach to calculate total factor productivity (TFP) considering that capital income share to be changed; and finally, estimating the effect of capital income share and it’s variation on TFP growth.   For this reason, the data of value added, capital stock, and labor compensation with constant values at 2011 as well as labor forces data of manufacturing industries in 31 Iran’s provinces during 2000-2014 have been collected. Findings show that the capital income share variation had positive effect on income per capita in provinces ‘manufacturing industries with value 11.5 thousand Rials. The growth accounting results indicate that classic factors contribution (labor and capital stock) of economic growth was 11.4 and 200 percent, respectively. Moreover, capital income share variation and Zuleta TFP contribution of manufacturing industries economic growth are 30 and -141 percent, respectively. Finally, outcomes of panel least squares (PLS) estimation show that capital income share variation has significant and positive effect on TFP growth, but income share level doesn’t significant effect during the considered period. In fact, a one percent increase in capital income share will increase the TFP growth by approximately 2.6 percent; which these are due to variation of factor abundant ratio and biased technological change in provinces ‘manufacturing industries of Iran.
