Abstract
This study analyzes the changes in the gateway functions of 11 container ports in Korea using the Herfindahl-Hirschman Index (HHI) and Shift-Share analysis to assess the effectiveness of government port policies. The HHI analysis indicates that the Southeast and Southwest Sea regions maintain high concentration levels, reflecting monopolistic structures. In contrast, the West Sea region, although still characterized as monopolistic by the HHI, is shifting towards an oligopolistic structure due to increased competition between Incheon and Pyeongtaek-Dangjin ports. The Shift-Share analysis examined shifts and shares of cargo volumes among ports within each region. It revealed that Busan Port initially faced cargo volume losses but later made a recovery. Gwangyang Port grew by attracting cargo volumes from the South Sea region under the government’s two-port policy; however, its competitiveness has significantly weakened recently. Incheon and Pyeongtaek-Dangjin ports have emerged as growth centers in the West Sea region, with steadily increasing cargo volumes that enhance the gateway functions of this area.
Key Words: container port, gateway port, EXIM containers, shift-share analysis, HHI
