面对资源短缺和日益增长的碳排放量,为探究改变传统发展模式,优化全社会绿色转型,促进绿色低碳循环发展路径,本研究基于2010-2021年中国30个省级面板数据,构建指标体系,运用熵权TOPSIS(tech-nique for order preference by similarity to an ideal solution)模型、耦合协调度模型和空间自相关模型,分析数字经济、低碳发展与新型城镇化三系统耦合协调度及其时空演变特征.结果显示:2010-2021年间,三系统综合发展水平均有显著提升,从地区上呈现"东高西低"的空间分布特征;三系统耦合协调度呈波动上升趋势,总体经历了"勉强协调→基本协调"阶段,整体水平不高;三系统在空间上表现为正向空间自相关性,相关性逐渐增强,空间分布向聚集状态演变;高-高集聚类型主要分布在东南沿海及中部地区且呈现出显著的扩散态势,协调发展水平"东南高西北低".根据实证分析结果,针对数字经济、低碳发展与新型城镇化耦合协调提出建议,为加强区域联动,补齐短板,促进绿色低碳循环发展提供参考.
Coupling and coordination spatiotemporal evolution of digital economy,development with low-carbon,and new urbanization
Changing the traditional model of development was studied to optimize the green transfor-mation of the whole society and the path of promoting the development with green,low-carbon and recycle in the face of resource scarcity and increasing emissions of carbon.An indexes system was constructed based on the panel data of 30 provinces in China from 2010 to 2021.The entropy weighted technique for or-der preference by similarity to an ideal solution(TOPSIS)model,coupling and coordination degree model and spatial autocorrelation model,the coupling and coordination degree of digital economy were used to an-alyze the coupling and coordination degree and spatiotemporal evolution of the three systems including digi-tal economy,development with low-carbon,and new urbanization.The results showed that the compre-hensive development level of the three systems was significantly improved from 2010 to 2021,showing a spatial distribution characteristic of"high in the east and low in the west"from a regional perspective.The coupling and coordination degree of the three systems had a fluctuating upward trend,and the overall level went from barely coordination to basic coordination,with a low overall level.The three systems exhibited positive spatial autocorrelation in space,with the correlation gradually increasing and the spatial distribution evolving towards the state of aggregation.The high-high agglomeration type was mainly distributed in the southeastern coastal and central areas and had a significant diffusion trend,with a coordinated development level of"high in the southeast and low in the northwest".Suggestions are proposed for the coupling and co-ordination of digital economy,development with low-carbon,and new urbanization based on results of em-pirical analyses.It will provide reference for strengthening regional action in chain,filling the weak spots,and promoting the development with green,low-carbon,and recycle.
