摘　　要：采用双固定效应模型对2003—2019年中国271个地级市的面板数据进行实证分析,探究生产性服务业集聚对区域经济发展差距的影响,以及技术创新和产业结构调整升级在其中发挥的机制作用。研究表明,生产性服务业集聚对区域经济差距存在先扩大后缩小的倒U形影响,但因经济发展水平的不同而存在区域差异性,东部地区呈现显著的倒U形趋势,西部和东北地区尚处于受影响的起始阶段,中部地区受东部影响不显著;生产性服务业集聚会通过发挥创新效应推动技术创新,进而影响区域经济发展差距;在生产性服务业集聚影响区域经济差距的过程中,产业结构调整升级起到中介作用。Using the panel data of 271 prefecture-level cities in China from 2003 to 2019,the dual fixed effect model was used to empirically analyze the impact of agglomeration of producer services on regional economic development gap,and the mechanism role played by technological innovation and industrial structure adjustment and upgrading.The research shows that the agglomeration of producer services exhibits an inverted U-shaped effect on the regional economic disparity,initially widening and subsequently narrowing.However,due to the varying levels of economic development in different regions,this effect shows obvious regional differences;the eastern region showed a significant inverted U-shaped trend,the western and northeastern regions were still in the germination stage of the inverted U-shaped trend,while the central region was not significantly affected by the eastern region.Agglomeration of producer services will boost the potential for technological innovation via the innovation effect,thereby influencing the regional economic inequality.In the process of agglomeration of producer services affecting regional economic disparity,the adjustment and upgrading of industrial structure acts as a mediator.
