Abstract
In this study, changes in total factor productivity of 12 Korean offshore fisheries between 1997 and 2009 were estimated through the Malmquist productivity index, which is a nonparametric method. Also, the cause of such changes in productivity of each fishery was analyzed more specifically by segmenting into factors for technological progress and tech- nical efficiency. As a result of this analysis, the total factor productivity change of the entire offshore fisheries was -6.0 %. Changes in the technical efficiency and technological level factors, respectively, contributed 0.2 and -6.2 % to this rate of decrease in total factor productivity; that is, inactivity of technological progress led to the decrease in productivity of the offshore fisheries. In addition, technological progress and technical efficiency were found to differently influence the change in total factor productivity of each fishery. In order for each fishery to improve productivity, better rational fisheries management policies by the government and efforts by the fishing industry and individual fishing business units must accompany factors that promote productivity increase.
