International Trade and Economic Growth in Nigeria


This study evaluated the impact of international trade on economic growth in Nigeria from 1986 to 2021.The variables used in this study comprised of gross domestic product as a dependent variable, while oil exports, non-oil exports, oil imports, non-oil imports and exchange rate are the explanatory variables. The employed variables have different order of integration ranging from zero and one, which led to the application of auto-regressive distributed lag (ARDL) model as the method of analysis. The ARDL model investigated long-run and short-run interactions among the variables. The results showed evidence of co-integrating equations amongst the variables. Hence, the key findings that satisfied the research objectives are (i) oil exports have significant positive impact on economic growth in Nigeria in both short-run and long-run. (ii) Non-oil exports exerted positive and significant influence on economic growth in Nigeria in both short-run and long-run. (iii). Oil imports negatively and significantly affected the growth rate of the Nigeria’s economy and (iv) non-oil imports affect the economic growth in Nigeria negatively and insignificantly in both the short-run long-run. The results imply that N1 rise in oil exports increases economic growth by N0.089 in the short-run and by N0.376 in the long-run; whereas N1 rise in non-oil exports increases economic growth by N0.047 in the short-run and N0.199 increase in the long-run. However, N1 rise in oil imports, decreases economic growth by N0.019 in the short-run and N0.092 decrease in the long-run; whereas N1 rise in non-oil imports, decreases economic growth by N0.022 in the short-run and N0.92 decrease in the long-run. Based on the findings, the study recommended that Nigerian government should make judicious use of proceeds from export of crude oil to diversify other productive sectors of the economy. Again, the activities of non-oil sectors like agriculture, industry, etc, should be stimulated to enhance non-oil exports in Nigeria.
