【摘要】 深入推进数字中国建设，是提振消费、扩大内需的重要抓手。本文基于数字生产体系视角构建数字中国建设综合评价指标体系，选取2014—2022年中国家庭追踪调查与政策文本数据，运用熵值法、核密度估计与固定效应模型进行数字中国建设水平的测度评估、时空演进分析与实证检验。研究发现：数字中国建设整体呈现由“低水平匀质”向“中高水平分散”的演进特征，并形成数字生产力先行培育、数字生产关系跟进建设的发展路径。数字中国建设具有显著的消费扩容提质效应，其中代表数字生产力的演化动力是驱动消费水平提升的关键力量，数字生产关系制度与场景构建是消费结构升级的主导因素。消费扩容效应在高学历群体中较为明显，消费提质效应在已退休、男性与乡村群体中更为显著。数字中国建设通过提高收入、缓解流动性约束、增强居民数字场景参与、提高居民数字素养带动消费。应进一步强化数字生产力建设、健全数字生产关系制度并培育高质量数字场景，充分释放数字中国建设的消费提振效能。更多还原

【Abstract】 Deepening the advancement of Digital China construction serves as a crucial lever for boosting consumption and expanding domestic demand.A comprehensive evaluation index system for Digital China construction is developed from the perspective of digital production systems.Using data from the China Family Panel Studies covering 2014 to 2022 and policy text data, this study employs the entropy method, kernel density estimation, and fixed effects models to conduct measurement evaluation, spatiotemporal evolution analysis, and empirical testing.The findings reveal that Digital China construction overall exhibits an evolutionary pattern from a low level homogeneous state to a medium high level dispersed state, and follows a development path of first cultivating digital productivity and then advancing digital production relations.Digital China construction has a significant effect on consumption expansion and quality improvement.The evolutionary driving force representing digital productivity is the key force driving consumption level improvement, while the institutional arrangements and scenario construction of digital production relations are the dominant factors for consumption structure upgrading.The consumption expansion effect is more pronounced among highly educated groups, whereas the consumption quality improvement effect is stronger among retired, male, and rural populations.Digital China construction drives consumption by increasing income, alleviating liquidity constraints, enhancing residents’ participation in digital scenarios, and improving their digital literacy.Efforts should be made to further strengthen digital productivity, improve the institutional system of digital production relations, and cultivate high quality digital scenarios to fully unleash the consumption boosting effectiveness of Digital China construction.更多还原
