摘要
文章基于黄河流域65个城市2011—2020年的数据,采用中介效应模型、门槛模型以及空间计量模型等考察数字经济促进高质量发展的内部效应及影响机理。研究结果表明:发展数字经济可显著提升黄河流域高质量发展水平;中介效应结果显示,产业多维演化是数字经济推动黄河流域高质量发展的重要媒介,产业多维演化通过了双重门槛检验,使数字经济对高质量发展的影响表现出非线性变化趋势;数字经济的正向溢出效应显著,分区域来看,数字经济在中游、下游地区是当地高质量发展的主要动力,在上游地区未产生显著影响,且数字经济仅可带动下游地区邻近城市高质量发展水平的提升。
Based on the data of 65 cities in the Yellow River Basin from 2011 to 2020,this paper uses the intermediary effect model,threshold model and spatial econometric model to investigate the internal effect and influence mechanism of digital economy promoting high-quality development.The results go as below:The development of digital economy can significantly improve the high-quality development level of the Yellow River Basin.The results of the intermediary effect show that industrial multi-dimensional evolution is an important medium for digital economy to promote high-quality development in the Yellow River Basin.Industrial multidimensional evolution has passed the double threshold test,and the impact of digital economy on high-quality development shows a nonlinear change trend.The positive spillover effect of digital economy is significant.From a regional perspec-tive,the digital economy in the middle and lower reaches is the main driving force for local high-quality development,but has not had a significant impact in the upper reaches,and the digital economy can only drive the improvement of the high-quality development level of neighboring cities in the lower reaches.
