摘　　要：本文基于非期望产出—超效率SBM模型对长江经济带三大城市群绿色TFP增长进行了评价,首次运用Dagum基尼系数对其空间协同性进行了测度与分解,并就影响因素与经济政策进行了分析。结论表明：各城市群绿色TFP均呈总体上升趋势,但其增长具有显著的非均衡态势。总体、区域间、区域内协同性均呈总体减弱态势,长中游区域内协同性最弱,长三角与长中游的区域间协同性最弱,区域间协同性是影响总体协同性的主要因素。经济发展水平、要素禀赋结构、外商直接投资、教育发展等影响因素对不同城市群TFP增长的影响大小和方向具有较大差异,这在一定程度上弱化了城市群之间以及城市群内部TFP增长的空间协同性。缩小区域间TFP增长差异是提升城市群整体协同性的关键。协调外商直接投资、调整教育资源分配、促进产业结构升级、创新资本利用方式等政策有助于促进城市群绿色TFP协同增长。Based on the super- efficiency SBM model with undesirable outputs, the green TFP growth of three urban agglomerations in the Yangtze River Economic Belt was evaluated. For the first time, the Dagun coefficient was used to measure and decompose its spatial synergy, and the influencing factors and economic policies analysis. The conclusion shows that the green TFP in all urban agglomerations shows a general upward trend, but its growth has a significant imbalance. Overall, inter -regional and intra- regional synergies are gener- ally weakened, with the weakest synergy in the middle and long reaches, and the inter - regional synergies between the Yangtze River Delta and the middle- long reaches are the weakest. Inter - regional synergy is the main factor affecting the overall synergy. The influences of economic devel- opment level, factor endowment structure, foreign direct investment and educational development on the TFP growth of different urban agglomerations have great differences in size and direction, which to a certain extent weakened the TFP growth among urban agglomerations and urban agglomerations space synergy. Reducing the TFP growth difference between regions is the key to enhancing the overall synergy of urban agglomerations. Policies such as coordinating foreign direct investment, adjusting the distribution of educational resources, promoting the upgrading of industrial structure, and using innovative capital can help promote the synergic growth of green TFP in urban agglomerations.
