摘要
完善数字基础设施对提高居民效用水平和增进民生福祉具有重要意义。基于中国家庭金融调查数据,借助“宽带中国”战略这一准自然实验,构建渐进双重差分模型评估数字基础设施对家庭消费的影响。研究发现,数字基础设施建设能有效提升家庭消费水平,不同形式的稳健性检验均支持这一结论。机制检验表明,数字基础设施建设通过促进居民就业和增加家庭信贷可得性,提升了家庭消费水平。异质性分析发现,数字基础设施建设对低人力资本家庭、中老年家庭以及中西部地区家庭消费的促进作用更为显著。因此,要持续推进数字基础设施建设,弥合数字鸿沟,提高数字经济包容性,满足家庭多样化消费需求,为扩大内需、提高居民生活水平创造有利条件。
Improving digital infrastructure is of great significance for enhancing residents'utility levels and people's wellbeing.Using the China Household Finance Survey data and leveraging the"Broadband Chi⁃na"strategy as a quasi-natural experiment,this paper constructs a staggered difference-in-differences model to evaluate the impact of digital infrastructure on household consumption.The study finds that the advance⁃ment of digital infrastructure significantly increases household consumption,with various robustness tests sup⁃porting this conclusion.Mechanism tests show that digital infrastructure development enhances household con⁃sumption by promoting employment and increasing the availability of household credit.Heterogeneity analysis reveals that digital infrastructure development has a greater promoting effect on household consumption for fam⁃ilies with lower human capital,middle-aged and elderly families,and families in the central and western re⁃gions.Therefore,it is essential to continue advancing digital infrastructure construction,bridge the digital di⁃vide,enhance the inclusiveness of the digital economy,meet diverse household consumption needs,and cre⁃ate favorable conditions for expanding domestic demand and improving the quality of living for residents.
