摘要
为探讨城市圈产业用水的驱动因素,以武汉城市圈为例,利用LMDI法将产业用水影响因素分为产业用水单耗、产业结构、经济规模和人口规模,分析不同因素对产业用水变化的效应。结果表明:从总体来看,经济增长和人口扩大促进产业用水增长,其中经济规模为主导促进因素;而产业用水单耗下降和产业结构调整对产业用水的增长起抑制效应。在区域分析中,武汉市、黄石市、孝感市和潜江市产业用水的因素效应与城市圈全域基本一致;鄂州市仅产业用水单耗下降对产业用水变化表现为抑制效应;黄冈市、潜江市、仙桃市和天门市仅经济增长对产业用水变化有促进作用。研究结果可为武汉城市圈产业用水规划与节水政策提供参考。
The driving factors of industrial water consumption in Wuhan city circle is discussed in this article. The driving factors of industrial water consumption are divided into industrial water consumption per unit,industrial structure,economic scale and population size based on Logarithmic Mean Divisia Index. From the overall point of view,economic growth and population expansion promote the increase of industrial water consumption,and the main factor is economic growth; decrease of industrial water consumption per unit and the adjustment of industrial structure have inhibitory effect on industrial water consumption. The effects of driving factors on industrial water consumption in Wuhan city,Huangshi city,Xiaogan city and Qianjiang city are substantially consistent with the overall effect; in Ezhou city,only the decrease of industrial water consumption per unit shows inhibitory effect; in Huanggang city,Qianjiang city,Xiantao city and Tianmen city,only economy growth shows promoting effect on industrial water consumption. The results provide reference for the planning of industry water consumption and water-saving policy in Wuhan city circle.
