东黄海鲐鱼渔业资源租金初探

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 sustainable yield，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。

Study on resources rent of Scomber japonicus in the East China Sea and the Yellow Sea

Resource rents play an important role in natural resources exploitation and management, which can promote a sustainable development for fisheries resources, and also provide a necessary capital for reproduction of fisheries resources. In this paper, we estimate the rent of fisheries resources of Scomber japonicus in the East China Sea and Yellow Sea in 2008, using bio economic model and rent capture in the maximum sustainable yield as a reference. This study suggests that the complete economic value of chub mackerel is 373.03 million yuan, the catch worth is 179.70 million yuan, while the maximum sustainable yield of the economic value is 157.89 million yuan in the East China Sea and Yellow Sea in 2008. With the growth of chub mackerel, the economic value is 13.81 million yuan which is an average increase in annual and fishing rent (net) is 9.81 million yuan. Therefore, the economic data are from China, Japan and South Korea based on the fishery in the year 2008, the accumulative yield and benefit in 5 years are 1.45 megaton and 0.40 billion yuan, the accumulative yield and benefit in 10 years are 3.10 megaton and 1.27 billion yuan, the accumulative yield and benefit in 20 years are 6.37 megaton and 3.04 billion yuan. For the above, we propose to have a reform for coastal fisheries resources management in China, to reduce fishing intensity by charging resource rent. This method is not only to ensure the sustainable development of coastal fishery resources, but also reflects the interests of resources owners, and this research result has an important significance to the sustainable development of coastal fisheries.
