Abstract
This paper examined the relationship between oil consumption and economic growth in OPEC countries within a panel cointegration and panel based error correction model by using data from 1980 – 2011. In this paper we use unit root test and cointegration test for empirical test as gross domestic production (GDP) and oil consumption according to ADF test was integrated of one, we used Granger causality test. The results indicate the presence of a long run relationship among real GDP and oil consumption. The short run results also indicate the causality running from oil consumption to economic growth and vice-versa, supporting the feedback hypothesis which asserts that energy policies oriented toward improvements in oil consumption efficiency would not adversely affect real GDP. In other words we can say that energy efficiency have not a significant effect on economic growth in long – run. For this country there are any casualty between this variables in long-run.
