经济系统可持续总量平衡核算——基于物质流核算的视角

Balancing Accounting of Sustainable Aggregate for the Economic System:A Perspective from EW-MFA

本文使用经济系统物质流核算与分析方法(EW-MFA)从物质维度研究中国经济系统的可持续性。我们核算了1990-2008年具有国际可比性的中国物质流总量指标。研究结果表明,除1998年外,中国经济的年度物质消耗持续增加,而物质效率呈现出四段式的发展趋势,反映出政府在八五、九五、十五和十一五期间实施不同宏观经济政策的作用效果。在此研究基础上,本文提出了将EW-MFA作为环境管理有效工具的改进措施和进一步研究的建议。

This paper attempts to study China＇s sustainable economy in terms of material flows by using the method of economy-wide material flow accounting and analysis （ EW-MFA）. We have compiled material flow indicators for China associated with international comparison during 1990 to 2008. Results show that the annual material consumption of China＇s economy continuously increased except for a slump around 1998,whereas the material efficiency exhibited a four-phase trend reflecting different macro-policies of the Eighth,Ninth,Tenth and Eleventh Five-Year Plans implemented by the central government. Based on the research,suggestions for methodology development and further research are given to improve EW-MFA as a more effective tool for environmental management.
