TAC 대상 유무에 따른 어업어종별 효율성 비교분석

Abstract

The object of this study is comparative analysis on korean offshore fisheries efficiency by TAC species. Fisheries efficiency is measured by Data Envelopment Analysis method(DEA) and Super-Efficiency. Decision making units are 13 fisheries(TAC target) and 9 fisheries(Tac non target). This study analyzed both TAC and non-TAC species by utilizing annual data from 2011 to 2015. The analyzed result of DEA method showed that the TAC target fisheries are more efficient than TAC non-target fisheries, but the result turned out to be partially significant by rank sum test. Also the results of the Super-Efficiency analysis showed that the efficiency of the TAC species was higher, but T-statistic implies that it is not significant. In the last part of this study efficiency analysis was conducted with 110 DMU including whole period of analysis. As result, TAC target species was efficient than non-TAC species. However, these results are not caused by TAC system, but to the differences in fisheries.
