| 摘 要： | 综合考虑产业用水效率、产业用水结构、经济水平、水资源禀赋及水资源开发利用率5个因素对中国用水效率的影响,基于扩展的Kaya恒等式建立因素分解模型,应用LMDI分解方法对1997~2008年中国用水效率变化进行分解分析,计算各驱动效应因素的相对贡献率,测度它们的影响程度和方向。结果表明:产业用水效率效应和经济水平效应是影响中国用水效率变化的最显著因素。通过计算各驱动效应的绝对贡献率,采用最小方差法将中国31个行政区(港澳台除外)确定为4种空间驱动类型,进而分析用水效率变化驱动效应的分布特点。研究结果对于正确理解中国用水效率的变化与经济发展之间的关系以及产业结构的调整与可持续发展研究具有一定的参考价值。

| Abstract: | Five factors respectively named industrial water use efficiency,industrial water use structure,economy development level,water endowment and water resources development ratio are comprehensively considered as the main factors that impact on the water use efficiency,and the factor decomposition model under the extended Kaya identity was established,the decomposition model was solved by the method of LMDI(Longarithmic Mean Divisia Index),then the driving effects of the five factors were calculated and the mai... |
