Abstract:
This paper empirically examined the relationship between oil revenue, non-oil revenue and economic growth in Nigeria over the period of 1981 to 2019 employing time series data, Augmented Dickey fuller test, Phillips-Perron test, Johansen Co-integration test and the lag length test, long run estimation dynamics and short run estimation dynamics all representing the estimation techniques. Findings from the analysis reveals that oil revenue has a positive significant effect on economic growth, however, in a special case like Nigeria where the resource theory is evident, it can be said that the government should invest massively in the non-oil sector so as to yield maximum result and boost economic growth. The result conducted also shows that non-oil revenue has a positive significant effect on economic growth. However, government at all levels should invest in both the oil sector and the non-oil sector in order to enhance economic growth thereby validating the Balanced Growth Theories.
This study, thus, implies that the sectorial contributions of non-oil revenue undermined. It is concluded that sectorial contributions of non-oil revenue is positive and significant to economic growth in Nigeria. Recommendations were made that, environmental, ICT, financial among others non-oil sectors should receive the same magnitude of fund as in the case of oil sector, i.e., the sector should be more funded and well equipped to ensure good outputs and contributions, government should review environmental factors and policy that may spur the economy significantly.
