The Kaiser–Meyer–Olkin (KMO) overall statistic delivers 0.625 as a result for the sample of port efficiency variables, which indicates the sampling adequacy of the chosen variables. The PCA extracted three factors (Table 6). The first component, which accounted for more than 40% of the total variance, incorporates the bureaucratic turnaround of a container, the terminal turnaround for loading and unloading of a container, the average waiting time for ships during congestion time, the average waiting time for ships without congestion in the port, and the time of port congestion during the year. Together, these variables could be interpreted as representing port's time efficiency.
