摘要
基于2004-2018年长三角41个城市的面板数据,采用空间杜宾模型探究了创新人才集聚对城市经济高质量发展是否具有空间溢出效应,并采用面板双门槛模型考察了创新人才集聚对经济高质量发展水平是否具有非线性影响。研究表明:(1)创新人才集聚对城市经济高质量发展水平具有显著非线性影响,创新人才集聚在一定规模内对经济发展质量产生边际贡献递增,而超过一定规模时,创新人才集聚对经济高质量发展会产生边际贡献递减;(2)创新人才集聚对经济高质量发展具有显著的双重门槛效应,存在结构性突变,区域创新能力并非越大越好,而是存在一定阈值,在该阈值范围内,人才集聚对经济高质量发展的促进效果最好。
Based on the panel data of 41 cities in the Yangtze River Delta from 2004 to 2018,this paper uses the spatial Dubin model to explore whether the agglomeration of innovative talents has a spatial spillover effect on the high-quality development of the urban economy,and uses a panel double-threshold model to examine whether the agglomeration of innovative talents has a nonlinear impact on the level of high-quality economic development.The research shows that the agglomeration of innovative talents has significant nonlinear effect on the high quality development level of urban economy.The agglomeration degree of innovative talents has an increasing marginal contribution to the quality of economic development within a certain scale,and when it exceeds a certain scale,the agglomeration of innovative talents will have a decreasing marginal contribution to the high-quality economic development.The agglomeration of innovation talents has a significant double threshold effect on high-quality economic development.There are structural mutations.Not the greater the regional innovation ability,but a certain threshold.Within this threshold range,talent agglomeration has the best effect in promoting high-quality economic development.
