摘要
该文将技术创新纳入研究框架,探讨数字经济对经济发展质量作用的四重效应,详细解析了数字经济对经济发展质量的作用机制,并利用2011—2022年中国30个省份的面板数据和空间杜宾模型进行了实证检验。研究发现,数字经济对经济发展质量存在显著的正向直接作用,技术创新在其中发挥着显著的正向中介效应;技术创新的中介效应存在空间异质效应,在东部和中部地区显著为正,在东北地区不显著,而西部地区不存在中介效应;数字经济对经济发展质量的作用存在显著的正向空间溢出效应和空间异质效应,东部地区的空间溢出效应最显著,中部和东北地区的显著性较低,而西部地区不显著。
This study incorporates technological innovation into the research framework,explores the quadruple effects of the digital economy on the quality of economic development,analyzes the mechanism of the digital economy on the quality of economic development in details,and empirically tests it by using panel data of 30 provinces in China from 2011 to 2022 and spatial Durbin model.Research has found that the digital economy has a significant positive direct effect on the quality of economic development,and technological innovation plays a significant positive mediating effect in it.The mediating effect of technological innovation has a spatial heterogeneous effect,which is significantly positive in the eastern and central regions,but not significant in the northeast region,and there is no mediating effect in the western region.The effect of digital economy on the quality of economic development has significant positive spatial spillover effect and spatial heterogeneous effect.The spatial spillover effect is most significant in the eastern region,the significance in the central and northeast regions is low,and the western region is not significant.
