어업여건 변화에 대비한 근해어업의 에너지 효율성 평가

Abstract

This study evaluates the energy efficiency of offshore fisheries by year and gear in preparation for changes in fishery circumstances such as CPTPP and 2050 Carbon neutral roadmap, and provides policy implications based on the results. Accordingly, this study compares estimated technical efficiency using SFA with the energy intensity of offshore fisheries. As a result of the analysis, firstly, it shows that the energy efficiency of offshore fisheries by year is decreasing. Secondly, among gears in the offshore fishery, the energy efficiency of the fleet and the drag net fisheries whose have a large supply of tax-free petroleum is evaluated differently depending on the indicator, so the four indicators need to be complementarily used. Thirdly, it shows that there is a weakly positive correlation between the vessel-age and the energy intensity. Therefore, to improve the energy efficiency of offshore fisheries, it is necessary to shorten the calculation cycle of tax-free petroleum supply limit and reduce the number of fishing vessels in the fleet. In addition, it is necessary to not only promote the development of fuel-saving fishing implements for drag net fisheries, also replace electric hybrid fishing vessels for aged fishing vessels.
