In countries where the rate of industrialization and growth is high, dependence on oil is constantly increasing. Factors such as the increase in oil reserves of OPEC countries, differences in oil extraction costs, oil supply and demand imbalances cause oil prices to fluctuate. Increases in oil prices in OPEC countries have an increasing effect on energy export revenues and government budget revenues. In an economy dependent on oil export revenues, the existence of new reserves or the increase in oil production changes the structure of the production and export sectors in favor of oil. OPEC countries, which generate income based on oil exports, lose their competitive power in foreign markets when they cannot invest in R&D, technology and productivity. This situation causes countries to have an economic structure dependent on imports, to increase their current account deficit and to decrease their growth rates. The purpose of this study is to examine the relationship between average annual crude oil price (nominal value in US dollars), gross domestic product (2010 prices and $) and exports (2010 prices and $) for OPEC member countries through panel data analysis.
