新质生产力视角下数字经济发展的时空分异及影响因素
The spatiotemporal differentiation and influencing factors of digital economy development from the perspective of new quality productivity:a case study of the five major urban agglomerations/economic belts in Northwest China
摘要
Abstract
As the key drivers of economic development in western China,the five major urban ag-glomerations/economic belts in the Northwest China are of importance for the scientific assess-ment of their digital economy development levels in promoting high-quality digital economic growth in the area.Based on the panel data from 33 prefecture-level cities within the five major urban agglomerations/economic belts in the Northwest China from 2011 to 2023,this paper con-structs an evaluation index system for the digital economy.The entropy method is employed to measure the development level of the digital economy,while methods such as cold and hot spot analysis,standard deviation ellipse,Dagum Gini coefficient and variance decomposition and geo-graphical detector are used to explore the spatial-temporal variation and influencing factors of its development level.The results show that:①The overall development level of the digital econo-my in the five major urban agglomerations/economic belts in the Northwest China is on an up-ward trend,with spatial differences gradually narrowing;②The hot spots of digital economy de-velopment are mainly concentrated in the Hohhot-Baotou-Ordos-Yulin Urban Agglomeration,the Guanzhong Plain Urban Agglomeration and the Hexi Corridor Economic Belt,while the cold spots are primarily located in the Lanzhou-Xining Urban Agglomeration.The development focus has shifted from northeast to southwest,showing a spatial agglomeration effect;③Regional de-velopment,human resources,technological drive and economic structure are the main factors in-fluencing the development of the digital economy.关键词
