摘要
基于中国八大综合经济区2008—2019年的面板数据,运用非期望产出Super-SBM模型测度其包容性绿色发展效率水平,并采用Dagum基尼系数分解法、莫兰指数和收敛性检验模型探究其区域差异、空间相关和收敛性特征。研究发现:我国包容性绿色发展效率整体水平偏低但上升态势明显,八大综合经济区呈鲜明梯度结构特征;区域间净差异是八大综合经济区包容性绿色发展效率空间差异的主要来源;八大综合经济区包容性绿色发展效率自2016年空间集聚状态稳定,并形成东部和北部沿海经济区“高—高”集聚,东北、长江中游和西南经济区“低—低”集聚的分布格局;除长江中游和西南经济区外,全国以及其余经济区均存在σ收敛,与绝对β收敛相比,考虑外部因素的条件β收敛检验中全国整体及各经济区的收敛状态未改变,但收敛速度有普遍提升,不同经济区的收敛特征和其对外部环境因素敏感度有显著差异。因此,应立足区域协同顶层设计,因地制宜采取措施缩小区域差异,进而推动我国经济的高质量可持续发展。
Based on the panel data of China’s eight comprehensive economic zones from 2008 to 2019,the undesired output Super-SBM model is used to measure the level of inclusive green development efficiency,and the Dagum Gini coefficient decomposition method,moran index and convergence test model are used to explore its regional differences,spatial correlation and convergence characteristics.The study finds that:China’s overall level of inclusive green development efficiency is low but it is rising,and the eight integrated economic zones are characterised by a distinctive gradient structure;Net inter-regional differences are the main source of spatial variation in the efficiency of inclusive green development in the eight integrated economic zones;The spatial agglomeration of inclusive green development efficiency among the eight comprehensive economic zones has stabilised since 2016,and has formed a distribution pattern of“high-high”agglomeration in the eastern and northern coastal economic zones,and“low-low”agglomeration in the northeast,middle reaches of the Yangtze River,and southwest economic zones;Except for the middle reaches of Yangtze River and southwest economic zones,the national and the rest of the six economic zones haveσconvergence,compared with absoluteβconvergence,the convergence state of the country as a whole and each economic region in the conditionalβconvergence test considering external factors remains unchanged,but there is a general increase in the rate of convergence,with significant differences in the convergence characteristics of different economic regions and their sensitivities to external environmental factors.Therefore,top-level design should be based on regional collaboration,and measures should be taken to narrow regional differences according to local conditions,thereby promoting economic high-quality and sustainable development of our economy.
