초록
본 연구는 최근 3년간 부산항과 광양항 컨테이너 터미널의 통계자료를 이용하여 컨테이너 터미널별 기술적효율성을 추정하였다. 효율성의 추정기법으로서 효율성 분석에 널리 사용되고 있는 자료포락분석(DEA: Data Envelopment Analysis) 기법을 이용하였다. 효율성 분석결과에 의하면 우암부두와 감만부두가 3년간 모두 효율성 값이 1.00으로 나타났으며 감천부두는 2003년과 2004년 2년간 효율성 값이 1.00이었다. 한편 광양항 1단계와 2단계 부두는 2004년 효율성 값이 각각 0.656과 0.614로 부산항에 위치는 컨테이너 부두에 비해 효율성이 낮다는 결론이 도출되었다.
Abstract
The purpose of this study is to analyse the relative efficiencies of the container terminal operation in the port of Busan and Gwangyang using Data Envelopment Analysis(DEA). The results show that the container terminals of Gamman and Uam are found to be the most efficient terminals in 2002, 2003 and 2004. Gamcheon is found to be the most efficient terminal in 2003 and 2004. Relatively most inefficient terminals include Gwangyang Phase 1 and Gwangyang Phase 2 terminal based on variable returns to scale assumption. Based on output-oriented measures the target output level of Gwangyang Phase 1 terminal which would render it pareto-efficient and improve its performance is 1,551,574TEU, 52.26% increase of its container throughput in 2004. The projected container throughput of Gwangyang Phase 2 terminal is 645,573TEU, 118.42% increase of their container throughput in 2004.
