利用经济投入产出表所提供的经济数据以及物质流分析所提供的社会代谢数据,建立了物质投入价值产出(PIMO)模型对生态经济系统的代谢进行量化分析。该模型基于一系列经济部门的物质平衡方程,可以较为方便地对生态经济系统的物质代谢进行模拟和分析。以中国为例,本文对该模型的建立和使用进行了演示,各类经济活动对生态经济系统代谢的影响得到了量化。 Using the economic data provided by the economic input-output table and the social metabolic data provided by the material flow analysis, a model of material input value output (PIMO) was established to quantitatively analyze the metabolism of the eco-economic system. Based on the material balance equation of a series of economic departments, this model can more conveniently simulate and analyze the material metabolism of eco-economic system. Taking China as an example, this paper demonstrates the establishment and use of this model. The impact of various economic activities on the metabolism of the eco-economic system has been quantified.
