【摘要】 分析了生产性服务业专业化集聚和多样化集聚对城市创新的影响作用及空间溢出效应机理,并利用我国2004—2015年249个地级及以上城市面板数据,运用空间杜宾模型对其机理进行了实证检验。结果显示:生产性服务业多样化集聚不仅能促进本地区城市创新的提升,还对周边地区存在显著的空间溢出效应,而生产性服务业专业化集聚仅能促进本地区城市创新的提升;高端生产性服务业多样化集聚能促进本地区和周边地区城市创新的提升,低端生产性服务业中仅有专业化集聚能促进本地区城市创新的提升;特大及大城市高端生产性服务业多样化集聚能促进本地区及周边地区城市创新的提升,而中小城市低端生产性服务业专业化集聚能促进本地区及周边地区城市创新的提升。更多还原

【Abstract】 This paper analyzed the impact and spatial spillover effect mechanism of specialized agglomeration and diversified agglomeration of producer services on urban innovation,using the panel data of 249 prefecture level and above cities in China from 2004 to2015,applying the spatial Durbin model to empirically test the mechanism.The results showed that the diversified agglomeration of producer services could not only promote the upgrading of local urban innovation,but also had a significant spatial spillover effect on the surrounding areas,while the specialized agglomeration of production services could only promote the upgrading of local urban innovation.The diversified agglomeration of high-end producer services could promote the upgrading of local and surrounding the urban innovation,while only the low-end specialized agglomeration of producer services could promote the local urban innovation.Diversified agglomeration of high-end producer services in megacities and large cities could promote the local and surrounding urban innovation,while the specialized agglomeration of low-end producer services in middle-sized and small cities could promote local and surrounding urban innovation.更多还原
