One of the main subjects, all governments are facing is the just distribution of income, and trying to improve it; because of the consequence of unjust distribution of income studying different aspect of it is very important. In this regard, we have studied the effects of different kinds of infrastructure; economic (energy, water, ICT), social (health, education), on the inequality of the Iranian provinces for the period of 2006-2016. We have used the Dynamic Panel Data and GMM models. The results show that enhancement of social and economic infrastructures will reduce the inequalities. According to research findings, the increase in social and economic infrastructures has reduced the income inequality in society. As infrastructure of healthcare, information and communication technology, energy and water have the most impact on income inequality, respectively. Therefore, in order to reduce inequality in deprived areas, the combination and optimal allocation of economic and social infrastructures should be considered.
