맘퀴스트 생산성 추정 모형을 이용한 원양참치어업의 어선별 생산성 변화 분석

Abstract

Using Malmquist productivity model, fixed effect model, and random effect model, this study analyzed the productivity of 18 overseas long line fishing boats and 23 overseas purse seine fishing boats for five years from 2013 to 2017. In the productivity index analysis for the entire overseas tuna fisheries, it was analyzed that the MPI for the overseas long line fisheries from 2013 to 2017 fell by an average of 0.3% per year, but the MPI for the overseas purse seine fisheries rose by an average of 5.6% per year during the same period. In the analysis of the determinant of productivity using fixed effect model and random effect model, fishing fees, cost of repair, and sea areas were selected as the determinant of productivity index for the entire overseas tuna fisheries. And these factors were analyzed as determinants that significantly affected TECI and SECI.
