It is expected that high revenues of natural resources provide the necessary capital to improve economic development and growth in resource-rich countries. But the economic performances of these countries has been weaker in comparison with similar countries without natural resources’ endowment in recent decades. In this study, the role of oil revenues in relationship between financial and total economic growth and the growth of non-oil sector in Iran is investigated during the years 1969-2017 using vector error correction model. The results show financial development has a positive effect on economic growth in both cases, but the effect of oil revenues on economy and its fluctuations has a negative effect on the relationship between financial development and economic growth. In the second part, the same model is estimated for the economic growth of the non-oil sector. The financial sector's development has a greater effect on the economic growth of the non-oil sector and the smaller negative impact of oil revenues on it.
