基于资源乘数的海岛生态经济模型与实证分析

The Ecological-economic Model of the Islands on the Basis of the Resource Multiplier and Empirical Analysis

生态经济系统是一个资源、环境、经济因素相互作用的复杂系统,二者耦合机理越来越受到人们的关注。在现有的经济、生态系统输入—输出模型基础上,又拓展了已有的研究成果,通过建立两个关系矩阵,把经济与生态系统紧密地联系在一起,并引入资源乘数构建了生态经济模型。该模型能够用来分析当最终需求发生单位变化时,资源存量受其变化的影响程度。在实证分析中,分三种情况计算了渔业资源的乘数,验证了模型的正确性。

The ecological-economic system is very complex,including resources, environment and economic sectors. The combing relationship between ecosystem and economy has been a focus by researchers. On the basis of the existing economic and ecological system Input-output Model, this paper extends the work of earlier researchers, i.e. by establishing two relation matrixes （ and）, conomy and ecosystem link closely, introduces resource multiplier into this research. The and the emodel can be used to analyze the changes in final demand in units, the degree of influence which the resource stock changes. In empirical analysis, we calculate three conditions of the fishery resources multiplier to verify the correctness of the model.
