So much effort has been made towards understanding the relationship between privatization and commercialization and the economic growth of Nigeria. Privatization and commercialization of pubic enterprises in every economy is introduced for the attainment of specific objectives which includes economic growth and stability. Data was collected and analyzed using ordinary least square method OLS. The result of the study shows that there is a positive but insignificant impact of private investment on the economy, this due to lack of investment in the private sector. On the strength of this evidence, this work recommends that the government should allow the private sector to establish major companies like electricity generating companies, water supply companies etc. This study finally concludes by saying that the impact of privatization and commercialization of public enterprises on economic growth can only take effective progress when the enterprises are wholly or partially in some cases handled and controlled by the private owner whom will not relent in the optimization of profitable enterprises.
