This study investigates the comparative effects of oil and non-oil exports on economic growth in Nigeria from 1990 to 2022. Using regression analysis, the research examines how changes in investment, oil exports, non-oil exports, and exchange rates impact Real Gross Domestic Product (RGDP). The findings reveal that non-oil exports significantly and positively influence economic growth, emphasizing the necessity of diversifying Nigeria's export base. Conversely, oil exports show a negative but statistically insignificant effect on RGDP, indicating limited impact despite the sector's economic prominence. Additionally, exchange rate depreciations positively affect economic growth by enhancing export competitiveness. However, investment changes do not exhibit a statistically significant effect on RGDP within the model. The study underscores the importance of policies aimed at export diversification, competitive exchange rate management, and investment attraction to foster sustainable and inclusive economic growth in Nigeria. The results suggest that reducing dependence on oil revenues and promoting non-oil sectors are critical for economic resilience and long term development.
