The result of unit root indicates that Augmented Dickey Fuller (ADF) shows that it is integrated of order one. The co-integration test conducted indicates that both the Trace and Max-Eigen statistics has two Co-integrating variables. Finally, the ECM (-1) is negatively signed and designates that the speed of adjustment from the short run dynamics to its long run equilibrium. The ECM (-1) value -0.603324 or 60 per cent and is internally consistent at 5 per cent. The study concludes that reasonable amount should be channelled into the various sectors examined to boost the economy of Nigeria and lessen the dependence on oil.
