Abstract

This paper presents the measurement of efficiency for container ports. Data envelopment analysis(DEA), as it is called, has particular applicability in the service sector. Applying mathematical programming techniques, DEA enables relative efficiency ratings to be derived within a set of analysed units. This paper investigates the efficiency employing DEA Model on data for 53 container ports covering 1995-2001 in the world and the change in efficiency for 7 years. As a results, port of Busan was evaluated as inefficiency port compare with major ports of the world except 1995year and 1996year. But After 1997year, efficiency of Busan port is increasing somewhat better every year.

본 연구는 부산항을 포함한 세계 주요 컨테이너 항만들의 효율성을 DEA(Data Envelopment Analysis)모형을 통해 상대적으로 분석함으로써, 부산항의 현재 위치와 더 효율석인 항만이 되기 위해 벤치마킹(Benchmarking)해야 할 대상을 구체화하였다. 또한, 본 연구에서는 일정시점의 효율성 분석이 아닌 1995년-2001년까지 7개년의 효율성을 시계열적으로 분석함으로써 각 항만의 효율성 변화할 살펴보았다. 분석 결과, 부산항은 95년, 96년을 제외한 나머지 연도에 대해서 비효율적인 항만으로 구분되었으며, 97년 이래로 효율성 지수가 다소 증가하고 있는 것으로 나타났다.
