摘　　要：在新时代城市建设过程中,产城融合和城市创新持续性成为两个重要的着力点。将长三角地区41个地级及以上城市作为研究对象,探索产城融合对长三角城市创新持续性的影响效果及作用路径。研究结果显示:(1)长三角产城融合度逐年上升,实现了从轻度失调向初步协调的积极转变。(2)产城融合能够有效提高城市创新持续性,且在90%分位数上对城市创新持续性发挥最大化的积极作用。(3)产城融合能通过推动产业结构转型、提高人才集聚程度、提升信息化水平三种途径提高城市创新持续性。(4)长三角地区的产城融合和城市创新持续性具有正向空间相关性,产城融合的提高可以通过正向空间溢出效应改善邻近城市的创新持续性,且相较于地理因素而言,经济因素下产城融合对城市创新持续性的正向溢出作用更强。In the new era,the process of city construction has focused on the integration of industry and city and the sustainability of urban innovation.The article uses a sample of 41 cities at the prefecture level and above in the Yangtze River Delta to explore the effects and paths of industry-city integration on the sustainability of urban innovation in the region.The results of the study show the following:(1)the integration of industry and cities in the Yangtze River Delta has increased year by year,realizing a positive shift from mild dysfunction to initial coordination.(2)Industry-city integration can effectively improve the sustainability of urban innovation and maximize this positive effect in the 90%quartile.(3)Industry-city integration can improve the sustainability of urban innovation by promoting industrial structure transformation,concentrating talent,and upgrading informatization.(4)There is a positive spatial correlation between industry-city integration and the sustainability of urban innovation in the Yangtze River Delta.Greater industry-city integration can improve the sustainability of innovation in neighboring cities through positive spatial spillovers,and these spillovers are stronger under the economic factor than the geographic factor.
