The transportation plays an important role in economy so the issue of development of transport has attracted much attention for every country and region in the world. There are lots of investigations about the transportation from regional to global scale, however, in these research, the spatial autocorrelation has not been mentioned while spatial autocorrelation related to the independence of variables which challenges the validity of the hypotheses. This study explores and analysis the occurrence of spatial autocorrelation in volume of freight which is investigated in 6 economic regions individually in Vietnam and whole country also. In order to evaluate the phenomena, this article used classic Moran I statistic based on the geographic information of research subjects in Vietnam which extracted from GADM (Database of Global Administrative Areas) and the data of freight volume collected from Statistical Yearbook of Vietnam 2018 published by General Statistics Office of Vietnam. The results show that there are existed spatial autocorrelation of transportation activities in Vietnam. Based on the findings, some research commendations are given for future investigation of transportation.
