基于边际效应分析的海洋资源环境承载力评估

海洋资源环境的开发利用可视为将海洋资源环境作为生产投入要素的广义生产行为,因此受边际效应递减规律的制约。本研究基于资源环境边际效应的经济学视角,以对海洋资源环境破坏较大的填海造地建设为研究重点,通过基于GIS的海洋资源环境边际机会成本评估和基于边际效应分析的海洋资源环境承载力评估模型,建立海洋资源环境承载力的评估理论和方法,重新认识海洋资源环境承载力在海域管理绩效评估和科学决策中的重要作用,为区域海洋资源优化配置提供新的方法体系;关键成果是构建基于边际效应分析的海洋资源环境承载力评估模型,模型将海洋资源环境纳入宏观生产投入要素,由宏观要素的边际收益测算承载力极限阈值,其中对海洋资源环境的市场价值和非市场价值的正确评估是承载力评估的关键。

Assessment of Marine Resources and Environment Carrying Capacity Based on Marginal Effect Analysis

The exploitation and utilization of marine resources and environment can be regarded as the generalized production behavior that takes the marine resources and environment as the input factors of production,so it is restricted by the law of diminishing marginal effect.Based on the marginal effect of the development and protection of resource environment in the view of economics,this study aimed to establish a set of method of marine resources and environment carrying capacity based on the assessment models of marginal opportunity cost on GIS and carrying capacity on marginal effect analysis,mainly focusing on the most devastating exploitation behavior of land reclamation to marine ecological environment.It is crucial to re understand the role of marine resource environment carrying capacity played in the performance assessment and scientific decision-making of sea-area management,from the point of marginal cost and benefit of sea area resources and environment.The key achievement was to construct the assessment model of marine resources and environment carrying capacity based on the marginal effect analysis.The model took the marine resources and environment into the macro production input factors,and calculated the threshold value of the carrying capacity by the marginal revenue of macro factors.It was the key for assessment of carrying capacity to correctly evaluate the market value and non market value of the marine resources and environment.The results could provide a new method system for rational allocation of regional marine resources.
