黄河流域水贫困与经济高质量发展的耦合协调关系

Coupling and Coordination Between Water Poverty and High-quality Economic Development in Yellow River Basin

[目的]对黄河流域水贫困与经济高质量发展的耦合协调性进行探析,以期为黄河流域水资源高效利用与经济高质量协同发展提供参考。[方法]基于2010—2019年黄河流域9省(区)的面板数据,运用熵权法确定指标权重,利用耦合协调度模型及灰色关联度等方法,分析黄河流域水贫困与经济高质量发展耦合协调度的时空演化特征与相互影响程度。[结果]①黄河流域各省(区)的水贫困指数普遍提升,经济高质量发展水平普遍较低,区域差异明显。②耦合协调度呈波动上升趋势,在空间分布上大致呈现“东高西低”的态势。③水贫困与经济高质量发展两个系统各指标间的灰色关联度系数都大于0.5,处于较高关联状态。[结论]黄河流域的水贫困程度和经济高质量发展水平整体上有所改善,耦合协调度水平整体上较低,大部分省份处于轻度失调阶段。

[Objective]The coupling and coordination between water poverty and high-quality economic development was analyzed in order to provide a reference for the efficient use of water resources and high-quality economic development in the Yellow River basin.[Methods]Based on data from nine provinces in the Yellow River basin from 2010 to 2019,The entropy weight method was used with data from nine provinces(or regions)in the Yellow River basin from 2010 to 2019 to determine the water poverty index weight.The coupling coordination degree model and gray correlation degree were used to analyze the coupling coordination degree and mutual influence between water poverty and high-quality economic development in the Yellow River basin.[Results]①The water poverty index of the provinces in the Yellow River basin generally increased over time,and the level of high-quality economic development was generally low,with obvious regional differences.②The degree of coupling coordination showed a fluctuating upward trend,with a general spatial distribution pattern of“high in the east and low in the west”.③The gray correlation coefficients between the indicators of the two systems of water poverty and high-quality economic development were both greater than 0.5,which was in a relatively high level of correlation.[Conclusion]The level of water poverty and the level of high-quality economic development in the Yellow River basin have generally improved over time,and the level of coupling coordination is generally low.Most provinces are in a state of mild imbalance.
