Abstract:
Nigeria has depended too long on exhaustible crude oil as the major source of its revenue, giving little
attention to other sectors capable of increasing its revenue base for viable development opportunities.
This study investigated the potentials that exist in the non-oil sectors of the Nigeria economy.
Specifically, the contribution of the agricultural, industrial, construction, trade and service sectors to
Nigeria's economic growth were evaluated. Time series data was utilized spanning from 1986 to
2016. Descriptive statistics analysis and Johannsen co-integration test were employed for the
analysis. Ordinary Least Square (OLS) and Error Correction Model (ECM) techniques were used to
assess the Nigeria non - oil sector contribution to gross domestic product (GDP). The OLS and ECM
findings revealed that agricultural and service sectors have positive significant impact on economic
growth in Nigeria, while industrial, construction and trade have negative impact on economic growth
in Nigeria. Therefore, the study recommends that the government should design a mechanism to
improve the efficiency and effectiveness of agricultural sector and service sectors in Nigeria, since
their contributions to GDP at long run were positive and statistically significant.
