摘要
以长三角城市群为研究对象,利用2010-2018年26个城市面板数据,对城市群内各城市高技术产业集聚水平进行测度,进一步运用空间计量模型,实证探究长三角城市群高技术产业集聚对城市创新的直接效应与空间溢出效应,并考察城市经济发展水平与外商直接投资两个环境变量如何通过长三角城市群高技术产业集聚对城市创新产出产生直接影响,以及在空间溢出过程中如何发挥调节效应。结果发现:各城市创新活动存在明显正向关联;城市高技术产业集聚对本城市创新产出具有显著直接促进作用,而对邻近城市的空间溢出效应显著为负;城市经济发展水平与外商直接投资在长三角城市群高技术产业集聚对城市创新的直接效应与空间溢出效应中均发挥显著调节作用。
In this paper,we take 26 cities of the Yangtze River Delta urban agglomerations as research objects.The panel data of these cities from 2010 to 2018 are used to measure the level of high-tech industrial agglomeration of cities.Moreover,the direct and spatial spillover effects of high-tech industrial agglomeration on city innovation in the Yangtze River Delta are explored based on the spatial econometric models.In addition,the moderating effects of urban economic development level and FDI could also be investigated.The following three points are shown in this paper:there is significant positive correlation between the innovation activities of each city in the Yangtze River Delta;urban high-tech industrial agglomeration promote innovation output of city conspicuously,however,the spatial spillover effect of high-tech industrial agglomeration on neighboring cities is evidently negative;both the level of urban economic development and foreign direct investment play remarkable roles in the direct and spatial spillover effects of high-tech industrial agglomeration on urban innovation in the Yangtze River Delta urban agglomeration.
