ABSTRACT

 This study analysed the Impact ofTrade Openness on Economic Growth in Nigeria using time series datafrom 1981 to 2017. The study utilized Multiple Linear Regression analysis, Augmented Dickey Fuller (ADF) Testfor unitroot, Granger Causality test and other stability tests. The results ofthe AugmentedDickey Fuller test, showed that the variables became stationary at the levelform thus, integrated oforder zero which implied no long term relationship in the scries. . The results ofthe Multiple Linear Regression analysis showed that the estimated coefficient ofthe predictor variable, Degree ofOpenness (DOP) was - 0.264319. By implication, a percentage increase in degree ofopenness resulted to a decrease in economic growth by 0.26% in Nigeria. The policy implication of this is that measures that limit trade openness in Nigeria will likely grow the economy. In addition, variables like foreign direct investment (FDI), Imports (IMP), Exports (EXP) andNominal Exchange rate (NEXCHR) were all independent variables. It is recommended that Nigeria shouldpursue a more closed which will improve economic growth in the country
