fair distribution of income is one of the most important macroeconomic goals of countries. Two different views are presented in relation to the impact of income inequality on economic growth by economic theorists. Many studies have been done in this regard which in some studies income inequality has positive effect on economic growth and others have negative effect. In most studies, the Gini index is used for income inequality which is based on income before tax deduction and forced payment .Since taxes as a tool to improve the income distribution situation, calculation of Gini coefficient based on income after mandatory payment and taxes can create a more accurate picture of income distribution and its consequences .Due to the effect of income redistribution on income inequality , the present study examines the effect of partial redistribution on economic growth by using the Iranian economy during 1978-2018 and using generalized method of moments ( GMM ) .The results of the study show that the relative redistribution has significant effect on economic growth. Based on the results , indirect relationship between economic growth and economic growth is confirmed by relative redistribution index .The results of this study show that taxes and deferred payment are the driving force of economic growth .While on the basis of conventional GINI coefficient , income inequality causes an increase in economic growth .Therefore , providing a proper measure of income inequality will result in more accurate understanding of income inequality and codification of policy making in order to equal income.
