THE CONTRIBUTION OF OIL AND GAS TO ECONOMIC GROWTH IN NIGERIA
Abstract
ABSTRACT
This study investigates the role of oil and gas revenues in Nigeria’s economic growth, focusing on their influence on GDP, employment, and infrastructure development from 1993 to 2023. Using trend analysis and an Autoregressive Distributed Lag (ARDL) model, it assesses both short- and long-term impacts of oil revenue. The research reveals that oil earnings significantly contribute to GDP, especially during periods of high oil prices, yet fail to catalyze proportional improvements in employment or infrastructure due to inefficiencies and the capital-intensive nature of the oil sector.
Despite the oil sector's contributions, Nigeria faces structural challenges stemming from over-reliance on crude oil exports. These include fiscal instability, exchange rate volatility, and limited investment in other productive sectors. The dominance of recurrent expenditure over capital investment has further hindered development. Government mismanagement, weak institutions, and corruption exacerbate these issues, stalling the broader economic benefits that oil wealth could bring.
The study draws from several theoretical perspectives, including the Resource Curse, Dependency, and Resource Endowment theories, to explain how oil abundance has paradoxically contributed to economic underperformance. It also explores the relationship between oil revenue and macroeconomic indicators, noting that the lack of diversification has left Nigeria vulnerable to global oil market fluctuations. Empirical findings confirm that while oil revenue boosts GDP, it has failed to support inclusive and sustainable development.
To ensure long-term growth and stability, the study recommends strategic diversification into agriculture, manufacturing, and technology sectors. It calls for better fiscal management, transparency in oil revenue use, and a reallocation of public expenditure toward infrastructure and human capital development. Only through structural reforms and a reduced dependence on oil can Nigeria achieve a more resilient and inclusive economy.
