2000~2010年中国资源产出率测算

在中国实际管理需求的基础上,构建了中国经济系统物质流分析(Chinese Economy-wide Material Flow Analysis - CEW-MFA)模型,对传统经济系统物质流分析工具进行了补充和拓展.在该模型的基础上将中国的RP定义为一组4个指标:直接物质投入(DMI)/GDP、本地物质消耗(DMC)/GDP、物质总循环量(CR)/(CR+DMI)与CR/固体废物总产生量(TG).测算了2000~2010年时间段的物质流及RP指标,并对其中的资源经济产出效率进行了国际比较.结果表明,中国现阶段的物质代谢总量高,2010年国家的DMI接近120亿t,DMC超过107亿t.中国资源的经济产出效率与主要发达国家相比仍有较大差距.2010年的GDP/DMI与GDP/DMC分别为2260,2512元/t.循环物质总量有较大幅度的增长,综合利用率CRR(1)与CRR(2)总体保持上升趋势.CRR(1)从2000年的16%升至2010年的23%,CRR(2)由46.8%升至54.1%.

Pilot calculation of resource productivity in Chinafrom 2000 to 2010

The model of Chinese Economy-wide Material Flow Analysis (CEW-MFA) was built on the basis of evaluating the requirements of management in China. Traditional tools of material flow analysis were complementarily developed. RP in China was defined as a group of four indicators on the basis of CEW-MFA: Direct Material Input (DMI)/GDP, Domestic Material Consumption (DMC)/GDP, Comprehensive Reutilization (CR)/(CR+DMI) and CR/Total Generation (TG).Finally, a pilot calculation of material flow and the four RP indicators of 2000~2010was carried out, as well as the international comparison of the two resource economic outputindicators. The result showed that total amount of current material metabolism of China is large, with DMI approximately 12 billion tons and DMC over 10.7 billion tons in 2010. There is still a considerable gap between RP of China and that of the developed countries. GDP/DMI and GDP/DMC in 2010 are￥2260/t and ￥2512/t, respectively. CR has a significant growth,while both CRR (1) and CRR (2) are overall increasing, with CRR (1) from 16% in 2000 to 23% in 2010 and CRR (2) from 46.8% to 54.1%.
