科技人才集聚对中国区域可持续发展的影响研究——基于空间溢出与门槛效应的实证检验

Research on the Effect of Scientific and Technological Talent Agglomeration on Regional Sustainable Development in China:Empirical Test Based on Spatial Spillover and Threshold Effect

区域可持续发展对于稳步推进中国式现代化具有重要意义,科技人才集聚为区域可持续发展提供了必要的智力支撑。基于2013—2020年中国30个省级面板数据,采用空间杜宾模型和门槛效应模型研究了科技人才集聚对区域可持续发展的影响。结果表明:中国区域可持续发展水平与科技人才集聚存在着严重的区域不均衡性,东部地区与中西部地区差距较大;科技人才集聚可以显著推动本区域可持续发展,且具有正向空间溢出效应;科技人才集聚对区域可持续发展的影响及溢出效应存在地区和人才集聚类型异质性,且不同地区需要集聚的人才类型也存在差异;科技人才集聚效果存在最优区间,集聚超过一定规模时反而会对区域可持续发展产生负面影响。

Based on the panel data of 30 provinces in China from 2013 to 2020,this paper analyzes the relationship between scientific and technological talent agglomeration and regional sustainable development.This research employs the spatial durbin model to empirically test the impact and spillover effect of scientific and technological talent agglomeration on regional sustainable development,and then further analyzes the research samples from different regions and talent agglomeration types.Considering the crowding effect of talent agglomeration,this paper proves the nonlinear relationship between talent agglomeration and regional sustainable development through threshold effect model.Results show that,regional sustainable development and scientific and technological talent agglomeration are both in tremendous inequality in China,with a large gap between the eastern region and the central and western regions.Scientific and technological talent agglomeration significantly promotes regional sustainable development,and has a positive spatial spillover effect.The relationship between them will be heterogeneous due to the different regions and talent agglomeration types.The scientific and technological talents from the eastern and western regions and those engaged in applied research and experimental development work have a better gathering effect.The agglomeration of scientific and technological talents of experimental development plays a more significant role in the sustainable development of the eastern region,and all kinds of talents promote the sustainable development of the western region.
