Abstract

This paper focuses measuring the efficiency of container yards on container terminals in Busan (Gasungdae, Shinsundae, Gamman, New Gamman, Uam, Gamchon, PNC) and Gwangyang(GICT, KEC, Dongbu, KIT) using Data Envelopment Analysis(DEA) approach. Container terminals in Busan and Gwangyang play an important role in the region's economic development. The results show that Shinsundae was an efficient DMU during the period of 2007 to 2009, while Gamman, New Gamman and PNC were efficient terminals in 2009. The very inefficient terminals were shown to be GICT, KEC, Dongbu and KIT. GICT(2009), KEC(2009), Dongbu(2008-2009), KIT(2009) on Gwangyang Port were found to be relatively the inefficient terminals in terms of the returns to scale. This study also finds that the efficiency of Shinsundae terminal was so high as to be abel to keep its efficiency in spite of the additional increase of the inputs from 2007 to 2009. Gamman terminal was in the decreasing returns to scale in 2009, while the other terminals were in the increasing returns to scale. It means that we are able to improve the efficiency of the Gamman terminal with increasing returns to scale through enlarging the scale.

터미널의 운영은 국가와 지역경제에 영향을 미친다. 부산항과 광양항의 11개 터미널로 GICT, KEC, 동부, KIT, 자성대, 신선대, 감만, 신감만, 우암, 감천, PNC 효율성 분석을 위하여 다양한 DEA(Data Envelopment Analysis)기법들을 이용하여 분석하였다. 신선대, 감만(2007년, 2008년), 신감만(2009년), PNC(2009년)터미널이 규모의 효율성이 1로 나타나 효율적인 것으로 나타났다. 특히, 신감만과 PNC는 2009년에 가장효율성이 높았다. 광양항의 GICT(2009), KEC(2009), 동부(2008-2009), KIT(2009)터미널은 낮은 효율성을 가지고 있는 것으로 나타났다. 감만터미널(2009년)이 규모수익체감(DRS)인 것으로 나타났으며 나머지 터미널은 규모 수익체증(IRS)인 것으로 나타났다. 규모 체감인 항만은 운영상의 효율성을 위한 전략이 필요하며, 규모수익체증인 항만은 규모확대를 통한 효율성 전략을 수립하는 것이 요구된다. 신선대 터미널은 2007년과 2009년까지 현재의 투입요소합을 최소 1.5배 이상 늘려도 100%의 효율성을 유지 할 수 있는 것으로 나타났다. 연도별 동태적 효율성 변화추이는 자성대는 계속 상승하고 있다.
