| 摘 要： | 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。

| Abstract: | Input-output analysis (IOA) has been applied to study the integrated ecological-economic systems for decades.In this article,a physical input monetary output (PIMO) model is developed to aggregate economic systems with the associated ecological systems.The PIMO model utilizes economic information integrated in monetary input-output tables (MIOTs) and societal metabolism information provided by the method of material flow analysis (MFA).The fundamental process of applying PIMO model to practice is to make a PIMO table based on an existing MIOT.The computational framework of the PIMO model is then expressed by a set of mathematical correlations to represent mass balances of each economic sector and the entire economic system.Although there are four major categories of uncertainty in this approach,the PIMO model is relatively easy and sufficient to study an integrated national economic system and associated ecological system.A general algorithm of PIMO analysis is presented in this article and exampled with a case study on China's economy.In the case study,a PIMO table for China's economy is compiled with 43 economic sectors,10 categories of resources,and 6 categories of wastes.Impacts on societal metabolism are studied by increasing final demands in different sectors.Each sector's influence on specific categories of resources or wastes is also studied by the PIMO model.Finally,the PIMO model is applied to evaluate a particular policy established by the Chinese central government.Results suggest that specific scenarios are suitable to achieve the predefined environmental goals. |
