The object of this study is to examine the relation between economic growth, in terms of gross domestic production (GDP) and petroleum production (PP) for the Organization of Petroleum Exporting Countries over the period of 2000-2016. The panel co-integration tests were applied to appraise the being of the relationship while the dynamic OLS (DOLS) and fully modified OLS (FMOLS) panel co-integration methods were applied to explore the long-run effect of PP on the GDP growth. Moreover, to estimate the short-run coefficient and causality relationship, the pool mean group (PMG) method was employed. The findings indicated that the GDP and PP are non-stationary and co-integrated series. The estimated panel coefficients using FMOLS, DOLS and PMG were calculated to be 0.64, 0.76 and 0.86, respectively. In addition, there was a unilateral causality from PP to GDP.
