Oil revenues and economic growth in Iran: evidence from the space-state model

One of the most important concerns of policymakers is achieving high economic growth. Accordingly, in the present study, the effect of oil revenues, human capital, liquidity and investment on economic growth in the period of 1991-2021has been investigated in the form of space-state model. The results of the research showed that the impact of oil revenues, investment and human capital on economic growth was positive and decreased over time. Also, liquidity has a uniform negative effect on economic growth. Therefore, improving the performance of the National Development Fund can provide the basis for a greater positive impact of oil revenues on economic growth. Also, if macroeconomic stability is not established, the increase in liquidity will lead to the transfer of money to non-productive activities and subsequently to the reduction of economic growth. On the other hand, in the conditions of macroeconomic instability, it will not be possible to increase the formation of fixed capital, and in this way, the improvement of economic growth will be limited.
