【摘要】 从数字乡村建设弥合城乡数字鸿沟的角度出发，利用我国2011—2020年30个省份的面板数据，采用PVAR模型，运用单位根检验、Granger因果检验、脉冲响应函数和方差分解等方法研究了数字乡村建设与城乡收入差距之间的动态关系。结果表明：数字乡村建设能够缩小城乡收入差距，在短期内，数字乡村建设对城乡收入差距存在单向Granger因果关系；从长期来看，数字乡村建设对城乡收入差距存在负向促进作用，并且保持着长期的稳定关系。城乡收入差距在很大程度上受到自身影响，但随着数字乡村建设的实施，数字乡村建设对缩小城乡收入差距的贡献度逐渐增大。更多还原

【Abstract】 In this paper, from the point of view of digital rural construction bridging the digital divide between urban and rural areas, based on panel data of 30 provinces of our country from 2011 to 2020, the PVAR model, the unit root test, Granger causality test, impulse response analysis and variance decomposition method were used to study the dynamic relationship between digital rural construction and urban-rural income gap. The results show that digital rural construction can narrow the urban-rural shrinkage gap. In the short term, digital rural construction has a unidirectional Granger causality to urban-rural income gap. In the long run, the construction of digital countryside has a negative promoting effect on the urban-rural income gap, and maintains a long-term stable relationship. The urban-rural income gap is largely influenced by itself, but with the implementation of digital rural construction, the contribution of digital rural construction to narrowing the urban-rural income gap gradually increases.更多还原
