【摘要】：采用基于非径向、非角度的SBM方向性距离函数的GML指数测度了我国274个地级以上城市的绿色全要素生产率,从总体、三大区域以及五大城市群三个维度对其收敛性进行了实证检验。结果显示:绿色全要素生产率总体呈增长趋势,东部地区城市增长率最高,西部地区城市最低,且其增长主要源于绿色技术进步;全国总体以及三大区域均不存在绝对σ收敛,但存在绝对β收敛和条件β收敛;五大国家级城市群均不存在绝对σ收敛,长三角、珠三角、京津冀和长江中游四个城市群则存在绝对β收敛,但成渝城市群不存在显著的绝对β收敛,且五大城市群均存在条件β收敛;三大区域或不同城市群的绿色全要素生产率均向其自身稳态水平收敛,但城市之间的差距仍会存在。
[Abstract]:The GML index based on non-radial and non-angle SBM directional distance function is used to measure the green total factor productivity of 274 cities in China. The convergence of three regions and five urban agglomerations is tested empirically. The results show that the green total factor productivity (TFP) is increasing in general, the urban growth rate is the highest in the eastern region and the lowest in the western region. And its growth mainly comes from the progress of green technology; There is no absolute 蟽 convergence but absolute 尾 convergence and conditional 尾 convergence in the whole population and in the three regions. The five state-level urban agglomerations do not have absolute 蟽 convergence, while the four urban agglomerations in the Yangtze River Delta, Pearl River Delta, Beijing-Tianjin-Hebei and the middle reaches of the Yangtze River have absolute 尾 convergence, but there is no significant absolute 尾 convergence in Chengdu-Chongqing urban agglomeration. And the five urban agglomerations all have conditional 尾 convergence; The green total factor productivity of three big regions or different urban agglomerations converges to its own steady state level, but the gap between cities will still exist.
