摘　　要：基于我国2006—2021年282个地级及以上城市的数据,运用多种面板模型,实证分析数字基础设施对区域经济差距的影响及其作用机制。研究结果显示:(1)数字基础设施能够缩小区域经济差距,并具有显著的区位、城市层级和人口密度异质性;(2)要素市场化在数字基础设施对区域经济差距的影响中发挥了调节作用;(3)数字基础设施对区域经济差距的影响有明显的空间溢出效应,本地数字基础设施建设对邻近地区区域经济差距具有抑制效应。基于此,建议国家应持续加大科技研发投入力度,重视对科研人才得培养;大力推进数字基础设施建设下沉,为区域经济增长提供强有力的支撑;要强化区域合作,实现区域间的产业融合,进而缩小区域经济差距。Based on the data of 282 prefecture-level and above cities in China from 2006 to 2021,the article empirically analyses the impact of digital infrastructure on regional economic disparity and its mechanism of action by using various panel models.The results of the study are as follows.Firstly,digital infrastructure is able to narrow the regional economic gap with significant location,city tier and population density heterogeneity,and this narrowing effect is mainly reflected in the eastern region with a higher level of digital infrastructure development,peripheral cities,and regions with high population density.In the eastern region,the estimated coefficient of digital infrastructure is significantly negative at the 1% level,while the estimated coefficient is not significant for the central and western regions;the digital infrastructure of peripheral cities narrows the regional economic disparity at the 5% significant level,while for central cities,the effect of digital infrastructure on regional economic disparity is not significant;the digital infrastructure of regions with high population density narrows the regional economic disparity at the 1% significant level,while for regions with low population density,the effect of digital infrastructure on regional economic disparity is not significant.Secondly,factor marketization can promote the reasonable and efficient flow of factors such as capital,technology and labor,as well as data,and the synergistic innovation among the factors,which is conducive to the rapid development of digital technology,and thus helps digital infrastructure playing its role in narrowing the regional economic gap.Factor marketisation plays a moderating role in the impact of digital infrastructure on regional economic gaps,and high factor marketisation levels help to increase the narrowing effect of digital infrastructure on regional economic gaps.Thirdly,to further test the reliability of the above empirical results,the article makes the following three attempts.In view of the possible ti
