摘要 运用基于非合意产出的SE-SBM模型测度了西北地区33个地级城市2010—2018年的水资源利用效率,并借助标准差椭圆、空间自相关性和空间马尔科夫链等方法,考察了其时空演变特征及俱乐部趋同的存在性。结果表明:尽管西北地区90.9%的城市水资源利用综合技术效率处于非DEA有效状态,但水资源利用效率总体上呈现波动上升的态势;水资源利用各项效率偏西北-偏东南的空间分布格局较为稳定,但综合技术效率和纯技术效率的方向性略有减弱,而规模效率的方向性略有增强;水资源利用各项效率均存在显著的空间正自相关性,且低-低类型的板块集聚特征更为显著;水资源利用各项效率均存在较强的俱乐部趋同特征,且空间作用对俱乐部趋同具有重要影响。

Abstract: In this paper, the SE-SBM model based on undesirable outputs is used to measure the water resources utilization efficiency of 33 prefecture-level cities in Northwest China from 2010 to 2018. And the spatial-temporal evolution characteristics and the existence of club convergence are investigated by means of standard deviation ellipse, spatial autocorrelation and spatial Markov. The results indicate that although 90.9% of the comprehensive technical efficiency of urban water resources utilization in northwest region is in a state of non-DEA-efficient, it shows a fluctuating upward trend generally, and the spatial distribution pattern of water resources utilization efficiency is relatively stable from the northwest to the southeast. Although the direction of comprehensive technical efficiency and pure technical efficiency is slightly weakened, the direction of scale efficiency is slightly enhanced. Similarly, there is a significant positive spatial autocorrelation for each efficiency type of water resources utilization, and the “low-low” type of plate agglomeration is more significant. And there is a strong club convergence in the efficiency of water resources utilization, and the spatial effect had substantial impact on club convergence.
