资源租金是自然资源价值的表现形式,合理收取资源租金既可促进渔业资源的可持续利用,同时也为渔业资源再生产提供必要的资本。以生物经济模型为基础,以最大可持续产量(maximum sustainableyield,MSY)处所获得的资源租金作为参考,估算2008年东黄海鲐鱼渔业资源租金状况。研究认为,2008年东黄海鲐鱼资源的全部价值为373.03百万元,其所捕捞的渔获价值为179.70百万元,MSY时的资源价值为157.89百万元。同时,随着鲐鱼的繁殖生长,平均每年渔获可增加的经济价值为13.81百万元,渔业净利润为9.81百万元。以2008年中日韩3国近海鲐鱼的生产数据和经济数据为基准,累计5年的产量和利润分别为144.63万吨和4.04亿元,累计10年的产量和利润分别为309.5万吨和12.67亿元,累计20年的利润636.87万吨和30.44亿元。针对上述情况,建议对我国近海渔业资源管理实行改革,通过收取资源租金的形式来降低捕捞强度,这不仅可以确保近海渔业资源的可持续利用,同时也体现了资源所有者的权益,研究结果对促进我国近海渔业可持续发展具有重要的借鉴意义。
Resource rent is the manifestation of the value of natural resources. Reasonable collection of resource rent can promote the sustainable utilization of fishery resources and provide the necessary capital for the reproduction of fishery resources. Based on the bioeconomy model and based on the resource rent obtained at the maximum sustainable yield (MSY), the rental situation of the fishery resources in the Eastern Yellow Sea in 2008 was estimated. According to the study, the total value of the catfish resources in the East Yellow Sea in 2008 was 373.03 million yuan, the catch value of the catfish caught was 179.70 million yuan and the resource value of MSY was 157.89 million yuan. At the same time, with the growth and development of catfish, the average annual economic value of catches increased by 13.81 million yuan and that of fisheries was 9.81 million yuan. Based on the production data and economic data of offshore catfish in China, Japan and the Republic of Korea in 2008, the total output and profit in the past five years were 1,446,300 tons and 404 million yuan, respectively. The accumulated 10-year output and profit were 3,095,000 tons and 12,67 respectively 100 million yuan, the cumulative 20-year profit of 6,368,700 tons and 3.044 billion yuan. In view of the above situation, it is suggested to reform the management of coastal fishery resources in China and to reduce the fishing intensity by collecting the rent of resources. This not only ensures the sustainable utilization of offshore fishery resources, but also reflects the rights and interests of resource owners. Promote China’s coastal fisheries sustainable development has important reference significance.
