摘　　要：基于2006—2020年中国三大城市群48个地级市数据,综合运用Super-SBM模型、Malmquist指数及收敛模型,系统考察中国三大城市群生态经济效率的时空演变和收敛特征。结果表明:(1)京津冀城市群生态经济效率水平呈上升趋势,长三角城市群趋于平稳,珠三角城市群呈下降态势;三大城市群生态经济效率的空间演变存在差异,主要表现为珠三角城市群呈现由“面”向“点”转变的趋势、长三角城市群呈“三点”分布状并逐步向外发散、京津冀城市群则以北京市为起点并逐步向南发展。(2)京津冀与长三角城市群存在σ收敛特征,珠三角城市群不存在σ收敛;三大城市群均存在绝对β收敛和条件β收敛,但收敛速度不一。Based on the data of 48 prefecture level cities in China’s three major urban agglomerations from 2006 to 2020,this paper systematically investigates the spatio-temporal evolution and convergence characteristics of eco-economic efficiency in China’s three major urban agglomerations by using Super-SBM model,Malmquist index and convergence model.The results show that:(1)The eco-economic efficiency level of the Beijing-Tianjin-Hebei urban agglomeration is on the rise,the Yangtze River Delta urban agglomeration is stable,and the Pearl River Delta urban agglomeration is on the decline;The spatial evolution of eco-economic efficiency of the three major urban agglomerations is different,mainly manifested as the Pearl River Delta urban agglomerations show a trend of transformation from“surface”to“point”,the Yangtze River Delta urban agglomerations show a“three-point”distribution and gradually spread out,and the Beijing-Tianjin-Hebei urban agglomerations start from Beijing and gradually develop southward.(2)The Beijing-Tianjin-Hebei and Yangtze River Delta urban agglomerations haveσconvergence characteristics,but the Pearl River Delta urban agglomerations do not haveσconvergence.There are absoluteβconvergence and conditionalβconvergence in the three major urban agglomerations,but the convergence speed is different.
