摘要 文章基于2013—2020年省域面板数据,从基础设施、融合发展、创新创业和数字应用四个维度建立了数字经济发展水平综合评价指标体系,测算出各地区数字经济发展水平,运用空间模型和门槛模型研究了数字经济对我国城乡居民收入差距的空间溢出和门槛效应。结果表明:(1)数字经济发展水平的提升有利于缩小城乡居民收入差距,且此种影响存在显著的空间溢出效应,即有利于周边地区城乡居民收入差距的减小。(2)数字经济对城乡居民收入差距的降低效应存在单门槛效应,只有当数字经济发展水平高于门槛值时,才能发挥其缩小城乡居民收入差距的作用。 Based on the provincial panel data from 2013 to 2020,a comprehensive evaluation index system from four dimensions is established:the infrastructure,the integrated development,the innovation and the entrepreneurship and digital application to measure the development level of digital economy in each region,and the spatial model and the threshold model are used to study the spatial spillover and the threshold effect of digital economy to the income gap between urban and rural residents in China.The results show that:(1)the development of the digital economy is conducive to the reduction of the urban-rural income gap,and there is a significant spatial spillover effect of such effect,which is beneficial to reducing the income gap between urban and rural residents in its surrounding areas;(2)there is a single-threshold effect of the digital economy on narrowing the income gap between urban and rural residents,and only when the level of digital economy development is higher than that of the threshold value,can it play the role in narrowing the urban-rural income gap.
