The study showed that government expenditure had a significant and positive impact on economic growth while imports, savings and unemployment rate had negative impacts on economic growth. Oil revenue also had a positive but insignificant impact on economic growth. The author’s recommendations includes among others the following: government should increase her investment on productive economic activities and government should diversify by also investing in other sectors of the economy since the impact of the petroleum industry on growth was found to be insignificant.
