환경친화적 선박재활용을 위한 국제 규범에 관한 연구

A Study on the International Instruments for the Environmentally Sound Recycling of Ships

This paper explores the infrastructure efficiency of the Korean large-sized trade seaports using DEA(data envelopment analysis and then finds out the characteristics of these trade seaports during the period 2001-2012. We try to think the implications of the infrastructure investment to the trade seaports. Main finding facts are as follows: 1)There have been decreasing tendencies of efficiency in terms of relative efficiency levels during the period 2001-2012. 2)Pohang trade seaport has shown the highest efficiency levels around 1, and Kwangyang trade seaport has shown the lowest efficiency levels 3)Ulsan trade seaport has maintained the 3rd ranking during the period 2001-2012 and shown DRS patterns and the very similar patterns to the average efficiency of 6 large-sized trade seaports. 4)Pyeongtaek trade seaport has shown high speeds of decreasing efficiency from roughly 1 to 0.6. 5)The tendency of DRS is stronger in Koreaʼs trade seaports during the past several years except Busan trade seaport. In particular, Korean large trade seaports have strong tendency toward DRS over time. 6)In terms of scale efficiency, Kwangyang and Ulsan trade seaport show the relatively higher scale efficiency during the period 2001-2012. Pyongtaek trade seaportʼs scale efficiency has the lowest scale efficiency. From these results, in Asian highly growing areas. we need consider serious overinvestment problems about the infrastructure of airports and seaports through various efficiency analyses.
