To answer to this question, data from 43 Sub-Sahara African countries was collected for 2017. Correlation and regression were performed to find the relationship between gross domestic product (GDP) and foreign direct investment inflows (FDI) in selected countries.
The results show that FDI did not impact significantly GDP for 2017.
The estimated regression coefficient of FDI on GDP is 13.394. This coefficient is not statistically significant. The p-value of the coefficient is 0.119, R-squared: 0.0581, Adjusted R-squared: 0.03512. The results are not surprising because the correlation between GDP and FDI, is weak, and the relationship can be ignored. The test of Pearson's product-moment correlation fails to reject the null hypothesis of the no existence of a significant linear relationship between FDI and GDP.
