基于物质流分析的京津冀区域物质代谢研究

Research on Material Metabolism of Beijing- Tianjin- Hebei Region Based on Material Flow Analysis

本文研究运用物质流分析方法，以京津冀地区作为研究对象，构建区域物质代谢分析指标，实证分析了京津冀地区2005～2012年间的物质代谢规模、强度、效率。结果表明：（1）京津冀物质代谢规模呈上升趋势，河北省物质代谢规模明显大于北京和天津；（2）河北和天津物质代谢强度呈上升趋势，北京市物质代谢强度呈下降趋势，且整体上低于河北和天津；（3）京津冀物质生产力2012年相比2005年分别提高了114.63％、74.38％和14.28％，环境效率分别提高了175.48％、86.65％、7.21％。研究结果可为京津冀协同发展提供科学依据和指导，也为该区域可持续发展研究奠定了基础。

Research on the use of material flow analysis , taking Beijing -Tianjin -Hebei region as the object , this paper con-structs the regional material metabolism analysis index and empirical analyzes the material metabolism scale , intensity and efficiency of Bei-jing-Tianjin-Hebei region in 2005-2012 .The results show that ：（1） the scale of Beijing -Tianjin-Hebei shows an upward trend , and the scale of Hebei is larger than the scale of Beijing -Tianjin;（2 ） the intensity of Hebei and Tianjin is rising . The intensity of Bei-jing is decreasing and lower than Hebei and Tianjin ;（3） Beijing -Tianjin-Hebei material productivity in 2012 increase by 114.63% , 74.38% and 14.28% , compared to 2005 and environmental efficiency improve 175.48% , 86.65% , 7.21% respectively . The results can provide scientific basis and guidance for the coordinated development of Beijing -Tianjin-Hebei region and laid the foundation for the sustainable development of the region .
