Nwosu, Samuel O. Okafor,Eze A. Eze, Olisaemeka D. Maduka & Ngozi C. Ewurum Abstract: Foreign direct investment (FDI) has been a vital source of economic growth in Nigeria, bringing in capital investment, technology and management knowledge needed for economic growth. This study aims at investigating the impact of FDI on economic growth in Nigeria using the autoregressive distributed lag (ARDL) model for the period, 1980-2019. Time series properties of data were examined using Augmented Dicker Fuller (ADF) and Phillip-Perron tests for unit root. The study revealed that FDI in the manufacturing sector had significant positive impact on economic growth in Nigeria. The study also provided evidence on the role of financial development and institutional quality in the FDI-growth relationship, which suggests that the level of financial development had significant effect on the FDI-growth relationship in Nigeria, while Institutional quality had no significant effect on the FDI-growth relationship. It was recommended, inter alia, that government spending should be targeted toward increasing productive activities and providing basic infrastructures.
