A Brief Measurement on the Clustering of Korean Main Seaports and Efficiency Change Using Cross-Efficiency Model and Integer Programming Method
The purpose of this paper is to show the brief empirical measurement using the cross-efficiency model and integer programming method for 13 Asia container seaports in 2009, 2010, and 2013 data for 3 inputs( depth, total area, and number of crane) and 1 output(TEU). After clustering using cross-efficiency model, efficiencies are increased in the Busan and Incheon ports. Results using integer programming method focused on the output(TEU) show that Busan port(Hongkong, Dubai, Ningbo, and Chingtao ports), Incheon port(Ningbo, Gwangyang, and Nagoya ports), and Gwangyang port(Nagoya, and Incheon ports) are clustered with the ports in the parentheses. After clustering, efficiencies are not definite in two ports and three ports clustering. The containerport policy planners should introduce and consider the cross-efficiency model and integer programming method when they measure the efficiency increasing plan for the main Korean containerports.
