数字经济、人才集聚与长三角高质量发展

Digital Economy,Talent Agglomeration and High-quality Development of the Yangtze River Delta

基于空间杜宾模型、空间调节模型,选取2010—2021年长三角41个地级以上城市数据,可以分析数字经济对长三角高质量发展影响的直接效应、空间效应及其衰减特征和人才集聚调节效应。研究结果显示:数字经济对长三角高质量发展有显著为正的直接效应和空间效应,且在中心城市和外围城市呈现异质性。空间效应具有衰减特征。当地理距离在500 km以内,空间效应逐渐增强;在600—800 km之间,空间效应逐渐减弱;大于800 km,空间效应不显著。人才集聚有显著的正向调节作用。提升人才集聚度有助于增强数字经济对长三角高质量发展的直接效应和空间效应。

Based on the spatial Durbin model and the spatial regulation model,this paper selects the data of 41 cities at or above the prefecture level in the Yangtze River delta from 2010 to 2021 to analyze the direct and spatial effects of digital economy on the high-quality development of the Yangtze River delta,the attenuation characteristics of the spatial effects,and the regulatory effects of talent agglomeration.The results show that the digital economy has significant positive direct and spatial effects on the high-quality development of the Yangtze River delta,and presents heterogeneity in the central and peripheral cities.The spatial effect has the characteristic of attenuation,when the geographical distance is less than 500 km,the spatial effect is gradually enhanced;between 600-800 km,the spatial effect gradually weakens;greater than 800 km,the spatial effect is not significant.Talent agglomeration has a significant positive regulatory effect,and improving the degree of talent agglomeration is conducive to enhancing the direct and spatial effects of digital economy on the high-quality development of the Yangtze River delta.
