In this study, cargo arrivals in each port were divided into coastal cargo ships and coastal passenger ships. The purpose of this study is to compare and analyze the mutual direction while examining the current status and rate of change of each port. The data used in the study were organized in the Transportation and Logistics section of Korea Statistical Information Service(KOSIS) Domestic Statistics. The analysis period is a total of 151 monthly data from June 2010 to December 2022. In this study, Incheon, Busan, Gwangyang, Jeju, Pyeongtaek/Dangjin and Mokpo were selected in order of the highest number of domestic cargo arrivals. We calculated the monthly rate of change compared to the same month of the previous year for each port. In terms of the rate of change for each port, Mokpo, Gwangyang, Jeju and Busan showed the highest rate of increase over the past 151 months. However, Incheon showed a slight decrease. In the correlation coefficient analysis for each port, Korea showed high correlation in the order of Incheon, Busan, Pyeongtaek/Dangjin, Jeju and Gwangyang. In the regression analysis in which Korea was the independent variable, all ports except Mokpo were statistically significant. In the fluctuation rate analysis, Mokpo and Gwangyang showed a relatively large flow, while Incheon showed a relatively small stable flow. As a result of the empirical analysis, Incheon still shows the largest number of cargo arrivals, but the rate of increase is relatively decreasing. As the roles of Pyeongtaek/Dangjin, Mokpo and Gunsan, which are located in the West Sea, are gradually increasing, the role of Incheon is judged to be relatively decreasing. On the other hand, cargo arrivals from Jeju, Mokpo and Gwangyang are relatively increasing, which we view as a positive sign. It is expected that the roles of Busan and Ulsan, which are recognized as existing major ports, will develop further in the future.
