摘要
推进降碳减污扩绿增长协同发展是新发展阶段实现经济社会高质量发展的内在要求。采用CRITIC-熵值法、Dagum基尼系数、方差分解、核密度分析与空间收敛模型等方法,分析2004~2021年全国及八大综合经济区降碳减污扩绿增长水平发展趋势、区域差异与结构来源、动态演进、收敛性。结果表明:(1)全国及八大综合经济区降碳减污扩绿增长水平持续向好,但地区发展水平不均衡特征仍然明显,呈现出沿海地区>全国均值>内陆地区的分布特征;(2)区域间差异是总体降碳减污扩绿增长水平差异的主要来源,具体来看,增长提质差异主要集中于全国及沿海地区,扩绿效益差异主要集中于黄河中游、长江中游、东北地区和西南地区,降碳水平差异在大西北地区重要性日趋提高;(3)八大综合经济区存在显著的空间溢出效应,黄河中游地区仅存在条件β收敛,全国及其他经济区均存在绝对β收敛和条件β收敛。
Promoting the synergistic development of cutting carbon dioxide emissions,reducing pollution,expanding green development and pursuing economic growth is an inherent requirement for realizing high-quality economic and social development in the new phase of progress.Using CRITIC-entropy method,Dagum Gini coefficient,variance decomposition,kernel density analysis and spatial convergence model,this paper analyzed the development trend,regional differences and structural roots,dynamic evolution and astringency of cutting carbon dioxide emissions,reducing pollution,expanding green development and pursuing economic growth level in China and eight comprehensive economic zones from 2004 to 2021.The results indicated that:(1)the level of cutting carbon dioxide emissions,reducing pollution,expanding green development and pursuing economic growth in both entire country and the economic zones had been consistently improving.However,there still existed an imbalance in regional development,with coastal areas demonstrating higher distribution characteristics compared to the national average and inland areas.(2)The inter-regional differences were the main source of the differences in the overall growth level of cutting carbon dioxide emissions,reducing pollution,expanding green development and pursuing economic growth.Specifically,differences in growth quality were mainly concentrated in the entire country and coastal areas and discrepancies in green expansion benefits were primarily concentrated in the middle reaches of the Yellow River,the middle reaches of the Yangtze River,Northeast region and Southwest region.The significance of differences in carbon reduction levels was increasingly pronounced in the Great Northwest region.(3)Significant spatial spillover effects were observed in the economic zones,while only conditionalβconvergence could be found in the middle Yellow River region.Moreover,both absoluteβconvergence and conditionalβconvergence presented cross the entire country and other economic zones.
