어선감척사업에 따른 주요연안어업의 자원효과 분석

Abstract

The purpose of this study is to estimate the resource recovery effect and the economic effect of the fishermen by the fisheries vessel buy-back program. First, this study standardizes the fishing efforts of coastal gill net, coastal trap, and coastal composite fisheries using Gavaris general linear model. Second, resource evaluation is performed by using vessel-buyback program data, and also CPY model based on exponential growth function is applied. In order to derive the effect of the vessel-buyback program, the MSY with the vessel-buyback program is compared with the MSY without the vessel-buyback program. Third, we compare the resource recovery level in the dynamic aspect using the Hamiltonian method of present value based on the growth of fishery resources and the exponential growth model. Finally, we compare and analyze producer surplus under the equilibrium of the MEY and the OA using bioeconomic model. In conclusion, the vessel-buyback program has shown an increase in resource growth and an economic improvement for the remaining fishermen. The result shows that the remaining fishermen is able to abtain an increase in producer surplus of about 65% due to the vessel-buyback program.
