摘要
基于DEA-SBM模型,运用空间自相关分析和地理探测器软件研究黄河流域山东段县域绿色发展效率的时空分异特征及影响因素。结果表明:2010—2020年黄河流域山东段整体绿色发展效率呈现下降趋势,从最优下降至中等。从时序特征来看,黄河流域山东段县域绿色发展效率变化差异显著,可分为持续降低、持续增长、稳定不变、先升后降、先降后升5种变化类型。从空间分布来看,2010年县域绿色发展效率空间分布呈随机态势,2015年和2020年空间集聚特征较为显著。高—高集聚区与热点区分布具有一致性,低—低集聚区与冷点区分布具有一致性,均主要分布在济南都市圈,且面积不断增大,济南市都市圈县域间绿色发展效率高低分化显著。黄河流域山东段县域绿色发展效率影响因子交互作用呈非线性增强效应。
Based on the DEA-SBM model,spatial auto-correlation analysis and geodetector software are used to study the spatio-temporal differentiation characteristics and influencing factors of green development efficiency in counties in Shandong section of the Yellow River Basin.It is showed that from 2010 to 2020,the overall green development efficiency of Shandong section of the Yellow River Basin shows a downward trend,from optimal to medium.From the perspective of time series characteristics,the changes of the green development efficiency in counties in Shandong section of the Yellow River Basin are significantly different,which can be divided into five change types,they are continuous reduction,continuous growth,stable and unchanged,first rise and then decrease,first fall and then rise.From the perspective of spatial distribution,the spatial distribution of the green development efficiency in counties showed a random trend in 2010,and the spatial agglomeration characteristics in 2015 and 2020 are more significant.The distribution of high-high agglomeration areas and hot spots is consistent,and the distribution of low—low agglomeration areas and cold spot areas is consistent,all of which are mainly distributed in the Jinan metropolitan area,and the area is increasing.The efficiency of green development between counties in the Ji'nan metropolitan area is significantly differentiated.The interaction of influencing factors of the green development efficiency in counties in Shandong section of the Yellow River Basin shows a nonlinear enhancement effect.
