摘要:

探讨数字经济对城乡收入差距的作用机理对促进城乡融合发展、实现共同富裕具有重要意义。基于2012—2022年甘肃省14市(州)相关数据,运用固定效应模型和空间计量模型实证分析甘肃省数字经济对城乡收入差距的影响机制及空间效应。结果表明:(1)甘肃省数字经济对城乡收入差距的影响呈“缩小-扩大-缩小”的非线性关系,从2022年开始处于数字经济扩大城乡收入差距的鸿沟期。(2)区域异质性显示,甘肃省数字经济对城乡收入差距的影响在不同区域有所差异,陇东南地区呈明显“倒N”型关系,陇中地区较为微弱,而河西地区不显著。(3)作用机制分析显示,产业结构升级和农业社会化服务是甘肃省数字经济影响城乡收入差距的重要机制。(4)甘肃省城乡收入差距存在显著的空间集聚现象,数字经济对城乡收入差距的直接效应、间接效应和总效应均表现为“倒N”型关系,说明数字经济对城乡收入差距的影响具有空间溢出效应。

Abstract:

Exploring the mechanism through which the digital economy influences the urban-rural income gap holds significant importance for promoting integrated urban-rural development and achieving common prosperity. Based on relevant data from 14 cities (prefectures) in Gansu Province of China from 2012 to 2022, this study employs a fixed effects model and a spatial econometric model to empirically analyze the impact mechanism and spatial effects of the digital economy on urban-rural income gap. The findings are as follows: (1) The impact of the digital economy on the urban-rural income gap in Gansu Province exhibits a nonlinear “narrowing-widening-narrowing” pattern and has entered a critical phase since 2022, with the digital economy widening the urban-rural income gap. (2) Regional heterogeneity analysis reveals that the influence of the digital economy on the urban-rural income gap varies across different regions of Gansu Province. Specifically, a pronounced “inverted N-shaped” relationship is observed in the southeastern region of Gansu, while the impact is relatively weak in the central region and statistically insignificant in the Hexi Corridor region. (3) Mechanism analysis indicates that industrial structure upgrading and agricultural socialized services are crucial channels through which the digital economy affects the urban-rural income gap in Gansu Province. (4) There is a notable spatial clustering phenomenon in the urban-rural income gap across Gansu Province. The direct, indirect, and total effects of the digital economy on the urban-rural income gap all demonstrate an “inverted N-shaped” relationship, implying the presence of spatial spillover effects in the digital economy’s influence on the urban-rural income gap.
