摘 要：
[目的]分析天山北坡经济带主要城市用水效率对于促进水生态文明城市建设,推动天山北坡经济带发展。[方法]基于2004—2015年天山北坡经济带7个主要城市面板数据,利用超效率DEA模型和Malmquist指数研究各城市用水效率及其时空差异。[结果](1)2004—2015年,天山北坡经济带7个主要城市的水资源利用效率总体呈波动上升趋势,且2004—2008年期间的用水效率低于2009—2015年;空间上,乌鲁木齐市、克拉玛依市、石河子市、昌吉市和阜康市水资源利用效率高于乌苏市和奎屯市;(2)2004—2015年天山北坡经济带7个主要城市水资源全要素生产力指数呈"W"型波动,增长不稳定;技术变化(techch)是制约天山北坡经济带7个主要城市水资源利用效率提升的主要因素;(3)SAR模型表明用水效率具有空间依赖性;在时空尺度上,在0.05显著水平下,总用水量、生活用水、人口和生态用水与用水效率显著相关,但城市间距离、工业用水和农业用水与用水效率的相关性不显著。[结论]政府应大力改进生产技术,普及节水工艺;优化产业结构,平衡各城市间的水资源投入比例,提高技术进步贡献率,是提高天山北坡经济带主要城市水资源利用效率的途径。

摘 要：
[Objective]To analyze the water use efficiency of the main cities in order to promote the water ecological civilization urban construction and the development of Northern Slope Economic Zone in Tianshan Mountain.[Methods]Based on the data from 7 main cities in the north slope of Tianshan Mountains in2004—2015,this paper analyzed the water use efficiency and the spatial and temporal differences of the cities by using the super efficiency DEA model and Malmquist index.[Results](1) Super efficiency DEA analysis showed that the utilization efficiency of water resources in the Northern Slope Economic Zone showed a rising trend,but fluctuated during 2004—2015,meanwhile,the water use efficiency during 2004—2008 is lower than that during 2009—2015.The water resources utilization efficiency in Urumqi,Karamay,Shihezi,Changji and Fukang City was relatively high,while the water resources utilization efficiency in Wusu andKuitun City was relatively low.(2) Malmquist index analysis result showed that the water resources TFP index in 7 main cities fluctuated greatly,and the growth was not stable,showed a "W"type fluctuation.Technical change was the main factor restricting the water resources utilization efficiency in the Tianshan Mountains.(3) SAR model indicated that the water use efficiency showed a spatial dependence.At the temporal and spatial scales,at the 0.05 level,significant correlations were found among the total amount of water,living water,water use efficiency and population and ecological water use.But the correlation between the distances between the cities and the related industrial water and agricultural water use and water use efficiency was not significant.[Conclusion]The government should make great efforts to improve the production technology,popularize water-saving technology,optimize the industrial structure,adjust the proportion of water resources and labor input and improve the contribution rate of technological progress,so as to improve the water resources utilization ratio of main cities in north slope of Tianshan Mountains.
