摘要 【目的/意义】共同富裕是中国特色社会主义的本质要求。推动城乡发展、缩小城乡收入差距是实现共同富裕的重要组成部分。从数字基础设施建设的视角解决城乡发展不平衡的问题,为实现共同富裕提供了决策支持。【设计/方法】基于数字鸿沟的视角分析了数字基础设施建设对城乡收入差距的影响机理,构建数字基础设施建设指标评价体系,采用双向固定效应模型和面板门槛模型考察数字基础设施建设对城乡收入差距的影响效应、机制及异质性。【结论/发现】数字基础设施建设扩大了城乡收入差距,并通过了一系列稳健性检验。深入分析其中的机制发现,由于存在数字鸿沟,数字基础设施有利于提高城镇居民人均可支配收入,但对农村居民人均纯收入的促进效应还尚未显现。对全国分地区样本检验发现,数字基础设施建设扩大城乡收入差距的效应在西部地区、非沿海地区更为显著,对东部地区、中部地区和沿海地区不存在显著影响。最后,采用门槛模型发现,数字基础设施建设对城乡收入差距影响存在非线性效应,当教育达到门槛值后,数字基础设施建设有利于缩小城乡收入差距;当农村金融发展低于第一门槛值时,数字基础设施建设扩大了城乡收入差距,当达到第一个门槛值和第二个门槛值之间时,数字基础设施建设缩小了城乡收入差距。 [Purpose/Significance]Common prosperity is the essential requirement of socialism with Chinese characteristics.Promoting urban and rural development and narrowing the urban-rural income gap is an important part of achieving common prosperity.From the perspective of digital infrastructure construction,this study is to solve the problem of unbalanced urban and rural development and achieve common prosperity.[Design/Methodology]Based on the perspective of digital divide,this study analyzes the impact and mechanism of digital infrastructure construction on urban-rural income gap,constructs an index evaluation system of digital infrastructure construction,and uses two-way fixed effect model and panel threshold model to investigate the impact,mechanism and heterogeneity of digital infrastructure construction on urban-rural income gap.[Conclusions/Findings]The digital infrastructure has widened the urban-rural income gap and passed a series of robustness tests.An in-depth analysis of the mechanism finds that due to the existence of digital divide,digital infrastructure is conducive to improving the per capita disposable income of urban residents,however,the promotion effect on the per capita net income of rural residents has not yet emerged.The test of samples from different regions across the country finds that the effect of digital infrastructure construction on expanding the urban-rural income gap is more significant in the western region and non-coastal areas,and there is no significant impact on the eastern region,central region and coastal areas.Finally,using the threshold model,it is found that the impact of digital infrastructure construction on urban-rural income gap has a nonlinear effect.When education reaches the threshold,digital infrastructure construction is conducive to narrowing the urban-rural income gap;while the rural financial development is lower than the first threshold,the digital infrastructure construction expands the urban-rural income gap.When the first threshold and the second threshold are reached,the digital infrastructure construction reduces the urban-rural income gap.
