| 遵循大国经济发展的规律,从理论上分析了数字基础设施与城乡收入差距之间的关系,并对2013—2020年省级面板数据进行了实证检验。研究发现,数字基础设施能够缩小城乡收入差距,并且可以通过助力农业增收和提高非农收入来缩小城乡收入差距;地区异质性分析表明,南方地区的数字基础设施对城乡收入差距的缩小作用优于北方地区。此外,数字基础设施对城乡收入差距存在基于人力资本、交通基础设施、城镇化水平的单一门槛效应,跨过门槛值后,数字基础设施缩小城乡收入差距的作用更为显著。因此,加快农村数字基础设施建设,推动城乡公共服务资源数字化供给和网络化服务均等化,形成以城带乡、共建共享的数字城乡融合发展格局,是缩小城乡收入差距的关键。 |

| Following the law of economic development of major countries, this paper theoretically analyzes the relationship between the digital infrastructure and the urban-rural income gap (abbreviated as the gap), and empirically tests the provincial panel data from 2013 to 2020. The conclusion shows that the digital infrastructure can narrow the gap, by boosting agricultural income and non-agricultural income; from the perspective of regional heterogeneity, the effect of digital infrastructure on the reduction of the gap in the southern region is significantly better than that in the northern region. Additionally, the digital infrastructure has a single threshold effect on the gap based on the levels of human capital, transportation infrastructure and urbanization, and the effect is more significant after exceeding the threshold. Therefore, the key to narrow the gap is to accelerate the construction of rural digital infrastructure, promote rural digital supply and networked services of public service resources, and form a digital urban-rural integration, co-constructing and sharing development pattern. |
