This paper highlights the result of a study carried out to examine the Geographic determinants of import traffic distribution at the Port Hartcourt Port. A substantial aspect of the study involved building a regression model to estimate import distribution from the Port. The import function was specified in log-linear form. The adequacy of the model was then tested; this, involved statistical experiments to obtain the R-squared, as well as t and f values. Further test on the adequacy of the model was conducted through diagnostic exercises designed to check for multicollinearity and heteroscedasticity, in the data used. Result obtained show that road distance and manufacturing industries are significant Geographic determinants of import Cargo distribution at the study Port. It is therefore important to take the two variables into account in any policy or planning exercise at Port Harcourt Port. |
