摘　　要：为探究我国城市集群发展产生的创新效应,从城市群内人口规模、人口流动以及物质流动三个角度出发,构造了三种城市集群度指标,使用284个中国城市的面板数据展开实证研究。基于两阶段最小二乘法的结果表明:城市集群发展能显著促进城市创新。人口规模、人口流动以及物质流动集群度每增加一个标准误,城市创新指数将分别提升1.571%、1.257%以及0.615%。加速人力资本累积和促进产业分工是城市集群发展促进创新的重要途径,但过高的落户门槛将显著削弱城市集群发展对创新的提升作用。城市集群发展对中部地区城市创新的促进作用更为明显,对东部与西部地区城市创新水平的提升作用相对较弱。受益于人口集聚效应,城市集群发展显著提升了中心城市的创新水平。外围城市往往面临人力资本流失困境,城市集群发展的创新效应较小,甚至阻碍了本地的创新发展。To explore the innovative effects of urban agglomeration development in China,this study constructed three indicators of urban cluster degree from the perspectives of population size,population mobility,and material mobility within urban clusters,and conducted empirical research using panel data from 284 Chinese cities.The results based on two-stage least squares method are as below.Firstly,the development of urban agglomeration can significantly promote urban innovation.For every one standard error increase in population size,population mobility,and material mobility clustering,the urban innovation index will increase by 1.571%,1.257%,and 0.615%,respectively.Secondly,accelerating the accumulation of human capital and promoting industrial division of labor are important ways for urban agglomeration development to promote innovation,but excessively high household registration thresholds will significantly weaken the role of urban agglomeration development in enhancing innovation.Thirdly,the development of urban agglomeration has a more significant promoting effect on urban innovation in the central region,while its effect on improving the innovation level of cities in the eastern and western regions is relatively weak.Lastly,benefiting from the population agglomeration effect,the development of urban agglomeration has significantly improved the innovation level of central cities.Surrounding cities from outside often face the dilemma of human capital loss,and the innovation effect of urban cluster development is relatively small,even hindering local innovation development.
