宁夏县域共同富裕水平的时空分异特征及其影响因素
Spatiotemporal Differentiation of Common Prosperity Levels in Ningxia's Counties and Their Influencing Factors
摘要
Abstract
Based on the panel data of 22 districts and counties in Ningxia from 2013 to 2022,this study investi-gates the spatiotemporal evolution and determinants of common prosperity levels in Ningxia's counties by employing the entropy weight method,exploratory spatial data analysis(ESDA),kernel density estimation,Dagum Gini coefficient decomposition,and a panel grey correlation model.The results reveal that:2013-2022,the proportion of counties with low and medium-low levels of common prosperity decreased significantly from 72.72%to 36.36%,while that of medium-high level counties increased by 50 percentage points,and high level counties emerged for the first time.A distinct north-high-south-low spatial pattern was observed.Spatial clustering intensified,with the global Moran's index rising from 0.413 2 in 2013 to 0.775 1 in 2022.Kernel density curves shifted rightward,indicating coordinated regional development.The total Gini coefficient exhibited a"rise-decline"trend,decreasing by 18.17%.Inter-regional disparities(82.72%average contribu-tion)dominated over intra-regional gaps(10.14%),highlighting regional inequality as the primary source of overall disparity.County-level variations in common prosperity were significantly influenced by economic development,urbanization,education,and infrastructure.关键词
