中文摘要:
      研究目标:中国城市群生态效率的区域差异、分布动态和收敛性。研究方法:运用基于序列DEA的SE-U-SBM方法测度城市群生态效率、利用Dagum基尼系数及其分解考察区域差异,通过核密度估计揭示分布动态,利用变异系数和空间面板模型检验收敛特征。研究发现:中国城市群生态效率存在较大空间差异,城市群之间差异是总体差距最主要来源;各城市群生态效率存在不同极化特征和分布延展性;八大城市群总体、不同层级城市群内部、各城市群内部均存在绝对β收敛和条件β收敛。研究创新:测度城市群生态效率的区域差异,刻画城市群生态效率分布动态,明确城市群生态效率收敛机制。研究价值:为分析城市群生态效率空间格局提供依据,对促进城市群协调发展具有政策启示。
英文摘要:
      Research Objectives: The paper studies regional differences, distribution dynamics and convergence of Eco-efficiency in China. Research Methods:SE-U-SBM method based on sequence DEA is used to measure Eco-efficiency of urban clusters, Dagum Gini coefficient and its decomposition are used to investigate regional differences, distribution dynamics are revealed by kernel density estimation, and convergence characteristics are tested by variation coefficient and spatial panel model. Research Findings:There are large spatial differences in the Eco-efficiency of urban clusters in China, the difference among urban clusters is the main source of the overall gap, the Eco-efficiency of each urban clusters has different polarization characteristics and distribution ductility, there are absolute β convergence and conditional β convergence in the overall urban clusters, different levels of urban clusters, and in all eight urban clusters. Research Innovations:The paper measures the regional difference of urban clusters Eco-efficiency, depicts the dynamic distribution of urban clusters Eco-efficiency, and clarifies the convergence mechanism of urban clusters Eco-efficiency. Research Value:The paper provides basis for analyzing the spatial pattern of urban clusters Eco-efficiency and promotes the coordinated development of urban clusters.
