A STATISTICAL ANALYSIS FOR INFRASTRUCTURE QUALITY OF INTERNATIONAL TRADE

Abstract

In this study, it is analyzed infrastructure quality by infrastructure type including roads, railroads, ports and airport transportation by using parametric hypothesis tests for the 108 countries across the world. According to the results from the study, there is not a significant difference between infrastructure quality of roads and ports. On the other hand, there are significant differences among the all the infrastructure types except roads and ports. It can be concluded that air transport infrastructure has the best infrastructure quality. The railroad infrastructure has the worst infrastructure quality. The infrastructure quality for roads and ports are better than railroad infrastructure but worse than air transport infrastructure. It is vital to develop infrastructure quality by infrastructure type to achieve better international trade conditions for the welfare of the global society.
