摘　　要：理论上,通过推动创新创业,数字经济能够显著提升居民生活质量。实证上,基于我国220个城市2011-2020年数据构建了数字经济、创新创业和生活质量综合指标,也进行了多维度的实证分析。结果表明:在进行工具变量和“宽带中国”试点作为准自然实验等一系列稳健性检验以后,数字经济依然明显地增进民生福祉。作用路径分析显示,激发“大众创业、万众创新”是数字经济积极作用于生活质量的重要机制。最后,门槛模型结果显示,数字经济对生活质量的边际效用存在非线性递增的特点,一定程度上揭示了数字经济与生活质量的内在联系,为进一步改善民生福祉提供了理论依据。To meet the growing needs of the people for a better life,this paper explores the effects of the digital economy in enhancing residents'quality of life and its path of action.By promoting innovation and entrepreneurship,the digital economy can significantly improve the quality of life for residents.Empirically,based on the data from 220 cities in China from 2011 to 2020,the paper constructs a comprehensive index of the digital economy,innovation and entrepreneurship,and quality of life and conducts a multi-dimensional empirical analysis.The results show that after a series of robustness tests,including instrumental variables and the“Broadband China”pilot as a quasi-natural experiment,the digital economy still significantly enhances people's well-being.The path analysis shows that stimulating“mass entrepreneurship and innovation”is an essential mechanism through which the digital economy actively contributes to the quality of life.Finally,the results of the threshold model show that the“marginal utility”of the digital economy on quality of life is non-linearly increasing.To a certain extent,this paper reveals the intrinsic link between the digital economy and quality of life and provides a theoretical basis for further improving people's well-being.
