中国八大综合经济区生态文明发展的区域差异及收敛性研究

研究目标:探究八大综合经济区生态文明发展的区域差异及其收敛性。研究方法:熵值法综合评价模型、Dagum基尼系数分解法以及σ收敛和β收敛。研究发现:八大综合经济区生态文明发展水平均保持上升趋势,但水平整体偏低且呈现鲜明区域非均衡特征;八大综合经济区生态文明发展的空间异质性特征突出,区域间差异是总体区域差异产生的主要根源;除全国以及南部沿海、黄河中游外,其余六个经济区均存在σ收敛;全国及东北、北部沿海、东部沿海、黄河中游、西南、西北经济区存在显著绝对β收敛和条件β收敛,但收敛速度差异显著;南部沿海和长江中游经济区不存在绝对β收敛,但存在不显著的条件β收敛;不同经济区的驱动因素和收敛情况各不相同,在制定政策和建设规划时应有所区别。研究创新:运用Dagum基尼系数分解法挖掘八大综合经济区生态文明区域差异的来源;构建纳入空间因素的计量模型检验八大综合经济区生态文明发展的收敛性。研究价值:对于缩小生态文明发展区域差异,促进生态文明协同发展具有重要意义。

Study on Regional Differences and Convergence of Ecological Civilization Development in Eight Comprehensive Economic Areas of China

Research Objectives:This study aims to explore the regional differences and convergence of ecological civilization development in China’s eight comprehensive economic areas.Research Methods:The entropy comprehensive evaluation model,Dagum Gini coefficient decomposition method,σ and β convergence are used to study the issue.Research Findings:Firstly,the developments of ecological civilization in the eight comprehensive economic areas all keep an upward trend,despite the level is generally low and shows a distinct regional imbalance.Secondly,the spatial heterogeneity of the development of ecological civilization in the eight comprehensive economic areas is prominent,of which interregional difference is the main source.Thirdly,there exists σ convergence in China’s most economic areas except the south coast and middle reaches of the Yellow River,and exists significant both absolute and conditional β convergence in China’s most economic areas except the south coast and middle reaches of the Yangtze River,whose absolute β convergence do not exist and conditional β convergence are not significant.Fourthly,the driving factors and convergence of different economic areas are not the same,therefore policies and construction plans should be made differently accordingly.Research Innovations:The sources of regional differences of ecological civilization in eight comprehensive economic areas are explored out by using Dagum Gini coefficient decomposition method,and the convergence of ecological civilization development is tested by building an econometric model incorporating spatial factors.Research Value:It is of importance to narrow the regional differences of China’s ecological civilization and to promote its coordinated development.
