摘 要:基于考虑非期望产出的超效率SBM模型及GML指数测度中国283个城市的绿色全要素生产率,从专业化集聚和多样化集聚两个维度,构建生产性服务业集聚与城市绿色全要素生产率的计量模型,运用系统广义矩估计(SYS-GMM)方法进行实证检验。研究发现:生产性服务业集聚对绿色全要素生产率的影响随城市规模等级差异、城市行政级别差异、行业结构差异而表现出异质性。高端生产性服务业在Ⅰ型大城市、超大及特大城市的专业化和多样化集聚均能促进绿色全要素生产率提升,但在超大及特大城市表现为多样化集聚效应更强,而在Ⅰ型大城市表现为专业化集聚效应较强,且环境规制对多样化集聚效应存在正向调节作用。中低端生产性服务业在中小城市适合于专业化集聚模式,而在Ⅱ型大城市适合多样化集聚模式。同时,行政级别较高的城市高端生产性服务业的多样化集聚效应具有明显领先优势。最后,为依托生产性服务业集聚促进绿色全要素生产率提升提供政策建议。The green total factor productivity of 283 cities in China is measured based on super-efficient SBM model considering unexpected output and GML index.From the two perspectives of specialized agglomeration and diversified agglomeration,this paper builds an econometric model of producer service agglomeration and urban green total factor productivity,and empirically test it through SYS-GMM.The results show that:the impact of producer service agglomeration on green total factor productivity is heterogeneous with the differences of city scale level,city administrative level and industry structure.The specialized and the diversified agglomeration of high-end producer services in type I big cities,super-large cities and mega-cities can promote green total factor productivity.The diversified agglomeration effect is stronger in super-large cities and mega-cities,while the specialization agglomeration effect is stronger in type I big cities.At the same time,the environmental regulation has positive adjustment effect on diversified agglomeration effect.The middle and low-end producer service industry is suitable for specialized agglomeration mode in small and medium-sized cities,while it is suitable for diversified agglomeration mode in type II big cities.At the same time,the diversified agglomeration effect of high-end producer services in cities with higher administrative level has obvious leading advantages.Finally,it provides policy suggestions for promoting green total factor productivity growth through the agglomeration of producer services.
