Oil became one of the pillars of Iran's economy from the beginning of the 14th century AH, and its traces can be seen in all political, economic and social developments since then. Iran's economy is affected by oil and its revenues through various mechanisms. The problem of this research is to analyze one of the dimensions of the effect of oil on Iran's political economy, that is, the government's economic policies between 2013 and 2021. The purpose of the research is to identify the effects of oil on the government's policies and to provide the basis for reducing the negative effects. The descriptive-analytical research method and the method of data collection will be library studies and official statistics. According to research data, domestic and international developments have caused fluctuations in oil production, price, and income, and these fluctuations are caused by certain economic policies such as financial indiscipline, inflationary programs, and relative neglect of the tax system. And it has resulted in an increase in the Gini coefficient. These policies lead to the occurrence of some economic-social phenomena and the fluctuation of economic indicators, such as the failure to achieve the goals of development plans, rising inflation rates, increasing or decreasing the class gap, creating employment in a limited way and ultimately disequilibrium. Industry, agriculture and service sectors have grown. Although in some cases, such as job creation, oil income has had positive consequences, but mainly the consequences of oil income fluctuations have been negative and hindered economic progress. پرونده مقاله
