The advent of containerization technology has resulted in inter-port competition due to the expansion of hinterlands. Two tendencies, namely concentration and deconcentration of container traffic, have been observed during this process. This study focuses on the comparative discussion of port concentration dynamics during the period of 1975-2005 in three countries in Eastern Asia: Japan, China and Korea. The concentration dynamics in these three countries are examined by the Geo-Economic Concentration index, which is a comparable concentration index in different countries. The results of concentration analysis show the diversified evolution dynamics of the countries concerned. Furthermore, the differences of evolution patterns are explained from the perspective of port development policies and port governance.
