The fiscal policies include a change in the government’s income and spending, In fact, the main purpose of this paper is to study the degree and the way in which the government’s income and spending effect the function of macroeconomic in the field of private section investment. The results of the presented estimate model in this article show that government income of Oil and Gas have positive effect and Tax have negative effect, and it’s spending has positive effect on the investment in the private section. And the budget deficit of government encourages investment in the private section. The method used for estimating the function of the private section investment in Iran is the ordinary least square technique. This research is focused on time period from 1350 till 1384.
