摘　　要：绿色发展是城市发展质量和竞争力的核心体现。文章基于效率视角,利用城市面板数据和非期望产出SBM模型,测度中国城市绿色发展水平,分析其时序演进特征,并采用变异系数和双固定效应空间杜宾模型检验中国城市绿色发展的收敛性。研究发现:第一,在考察期内,中国城市绿色发展水平较低,整体呈现波动上升的趋势。第二,中国城市绿色发展水平及其增速存在明显的区域差异性。第三,基于全国层面和四大区域层面的共性变化特征考量,中国城市绿色发展水平仅在2004-2006年与2017-2019年两个时间段内,分别具有短期的σ收敛和发散特征,而在其他年份中均未呈现出收敛或发散趋势。第四,空间收敛性分析显示,无论是全国城市样本,还是四大区域城市样本,城市绿色发展水平均不存在绝对β收敛与条件β收敛特征。Green development is the core manifestation of the quality and competitiveness of urban development.Based on the perspective of efficiency,this paper uses urban panel data and unexpected output SBM model,measures the level of urban green development in China,analyzes their temporal evolution characteristics,and uses coefficient of variation and double fixed effect Spatial Dubin Model to test the convergence of urban green development in China.The research findings are as follows:Firstly,during the investigation period,the level of urban green development in China is relatively low,showing an overall fluctuating upward trend.Secondly,there are obvious regional differences in the level and growth rate of urban green development in China.Thirdly,based on the common characteristics of changes at the national and four regional levels,the level of urban green development in China shows short-termσconvergence and divergence characteristics only in 2004-2006 and 2017-2019,while in other years,there is no convergence or divergence trend.Fourthly,the spatial convergence analysis shows that there is no absoluteβconvergence or conditionalβconvergence characteristics in the level of urban green development,whether it is the national city sample or the four major regional city samples.
