摘要: 运用考虑非期望产出的DEA-Malmquist模型测算2001—2018年长江经济带11个省(市)水资源利用效率的变化,运用ESTDA模型对水资源利用效率时空变化进行分析。结果表明,在观察期内长江经济带水资源利用效率稳步提高,水资源利用效率空间集聚现象整体显著,具有一定波动性,容易在空间形成相互毗邻的联动区域,其中HL集聚、HH集聚容易出现在上游与下游沿海地区,上游地区水资源利用效率局部空间结构更加动态;正向协同增长省份占总省份数的54.54%,主要集中在中下游地区;从时期来看,水资源利用效率时空凝聚性略强于时空流动性,具有一定的可塑性,故需要加强区域间合作,优化投入资源在空间上的布局,提高水资源利用效率。

Abstract: The DEA -Malmquist model that considers undesired output was used to calculate the changes in water resource utilization efficiency(WRUE) of 11 provinces(cities) in the Yangtze River Economic Belt from 2001 to 2018, while ESTDA was used to analyze the temporal and spatial changes of WRUE. The results showed that the WRUE of the Yangtze River Economic Belt was increasing during the observation period. The spatial agglomeration of WRUE in the Yangtze River Economic Belt was significant with volatility to some extent. The WRUE was more likely to form adjacent linkage areas in space. To be detailed, HL pattern agglomeration and HH pattern agglomeration tended to appear in upstream and the coastal areas downstream. The local spatial structure of WRUE in the upstream region was more dynamic. The provinces with positive synergistic growth accounted for 54.54% of the total, mainly located in the middle and downstream regions. From the perspective of the period, the spatio-temporal cohesion of WRUE was slightly stronger than the spatio-temporal flux, but it was still plastic. Therefore, it is necessary to strengthen regional cooperation, optimize the spatial distribution of input resources, and improve the utilization efficiency of water resources.
