Eze & Prof. Samuel O. Okafor 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 and Johansen Cointegration test. The study revealed that FDI manufacturing has significant 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 role in the FDI-growth relationship in Nigeria, while Institutional quality had no significant role in the FDI-growth relationship in Nigeria.It was recommended, inter alia, that Government spending should be targeted towards productive activities and improvement of infrastructures.
