摘　　要：我国黄河几字湾地区资源环境保护与经济发展矛盾日益突出,人地关系日趋紧张,亟需寻求一条可持续发展道路。基于2009—2019年黄河几字湾地区20个市(县)的面板数据,通过构建可持续发展评价指标体系,运用熵权法、Kernel密度估计和Dagum基尼系数等方法,对黄河几字湾地区可持续发展的动态演变特征和区域差异进行研究。结果表明:(1)时间上可持续发展水平呈波动上升趋势;经济实力、社会民生、生态环境、创新驱动和对外开放5个维度的得分年均分别增长0.72%、1.90%、0.87%、-0.10%、-1.42%。(2)空间上呈现出“北高南低”的分布格局;45.00%的城市可持续发展水平有所提高,整体上呈良性演变态势。(3)总体基尼系数呈“下降-上升-下降”波动的下降趋势,区域差异有缩小趋势;区域间差异是总体差异的主要来源。In Jiziwan(n-shape bent)region of the Yellow River in China,the contradiction between resource and environmental protection and economic development has become more prominent.The human-land relationship has also become more tense,requiring a sustainable development road.Mastering the status quo of its sustainable development level is the foundation of the region’s sustainable development.Therefore,this paper constructed an evaluation index system for sustainable development to scientifically measure its sustainable development level.Aiming at the geographical advantages of Jiziwan of the Yellow River,we incorporated innovation and opening to the outside world into the sustainable development index system,besides the following dimensions:economic strength,society and people’s livelihood,and ecological environment.Based on panel data from 2009 to 2019 of the 20 cities in Jiziwan of the Yellow River,we employed the entropy method to estimate the sustainable development level.On this basis,we used the Kernel density estimation method and GIS technology to reveal the temporal and spatial evolution features.Additionally,we employed the Dagum Gini coefficient method to analyze regional differences.The results are as follows.(1)The sustainable development level of Jiziwan of the Yellow River shows a fluctuating upward trend from 2009 to 2019.The region’s average comprehensive level score increases from 0.405 to 0.419.However,the sustainable development level of the 20 cities is generally low,with an average comprehensive level score of 0.428.Additionally,the average annual score increase of the five dimensions:economic strength,society and people’s livelihood,ecological environment,innovation,and opening to the outside world,are 0.72%、1.90%、0.87%、-0.10%、-1.42%,respectively.(2)The spatial distribution of the sustainable development level is not balanced and shows the distribution features of“high value in the northern area and low value in the southern area”.Specifically,cities with higher comprehensiv
