摘　　要：基于Landscan全球人口动态分布数据测算我国各省份的多中心集聚,进而运用工具变量估计和中介效应模型考察省域多中心集聚对城市创新水平的动态影响、作用机制及约束条件。研究结果显示:首先,整体上看,城市创新水平随着所在省份多中心集聚程度的增加呈现显著的倒U型变化趋势,但目前我国绝大多数省份的多中心集聚尚未达到最优水平。其次,分样本检验发现,多中心集聚对城市创新水平的倒U型影响主要存在于大城市和内陆地区,中小城市和沿海地区的城市创新水平则随着多中心集聚程度的增加而提高。机制分析显示,市场一体化与要素流动是多中心集聚影响城市创新水平的重要途径。进一步研究发现,多中心集聚对城市创新水平的作用效果会受到省域内城市距离和基础设施的影响。研究结论为从创新驱动视角思考区域空间提供了一定的经验启示。In this paper,poly centric agglomeration index of each province is constructed based on Landscan data,and the impact of polycentric agglomeration on urban innovation and the mechanism of action were investigated by using instrumental variable estimation.The results show that,on the whole,urban innovation presents a significant inverted u-shaped change trend with the increase of poly centric agglomeration.Meanwhile,there are several regions in China where urban innovation is inhibited by excessive polycentric agglomeration.According to the sub-sample test,the inverted u-shaped impact of polycentric agglomeration on urban innovation is mainly reflected in large cities and inland areas,while the innovation of small and medium-sized cities and coastal areas can significantly benefit from the development of polycentric agglomeration.In addition,market integration and the factor flow are important ways for polycentric agglomeration to affect urban innovation.Further research shows that the effect of polycentric agglomeration on urban innovation is affected by urban distance and infrastructure.
