摘　　要：数字技术的应用与发展,是现阶段中国经济高质量发展的需要,是产业结构升级的重要技术支撑。以京津冀地区13市2011—2021年面板数据为基础,运用双固定效应模型、中介效应模型、门槛效应模型等多种计量方法对数字技术对产业结构升级的影响进行实证分析。研究结果表明,数字技术对产业结构升级具有促进效应;在地区异质性分析中发现数字技术与产业结构升级的关系在资源型与非资源型城市间尚未产生显著性差异。进一步分维度来看,数字技术对产业结构升级的促进作用主要源于数字技术应用;随着产业结构升级分位点位置的上升,数字技术对产业结构升级的促进效应呈现逐渐增强的特征,使京津冀地区存在数字鸿沟的风险。此外,数字技术对产业结构升级的影响具有经济发展水平的门槛特征,当经济发展水平不断跨过门槛值时,数字技术对产业结构升级的促进作用会增强;数字技术可以通过投资拉动和金融发展效率促进产业结构升级,而市场消费需求和人力资本结构高级化则在其影响中起到遮掩效应。The application of digital technology is the need for high-quality economic development in China,and an important technical support for the upgrading of the industrial structure.On the one hand,research on the impact of digital technology on industrial structure upgrading is mostly from the national perspective but ignores the regional perspective;on the other hand,research on the impact mechanism of digital technology focuses on the sup-ply side,ignoring the influencing factors of the demand side,so there is room for further study.Additionally,fur-ther optimizing the industrial structure of the Beijing-Tianjin-Hebei region is of great significance in promoting re-gional high-quality development.Therefore,this paper studies the impact of digital technology on industrial struc-ture upgrading based on the Beijing-Tianjin-Hebei region,and studies its impact mechanism through both supply and demand sides.This paper provides reference for promoting industrial structure upgrading and achieving high-quality development in the Beijing-Tianjin-Hebei region.Based on the panel data of 13 cities in the Beijing-Tianjin-Hebei region from 2011 to 2021,this paper empiri-cally analyzes the impact of digital technology on industrial structure upgrading by using double fixed effects model,intermediary effect model,and threshold effect model.The results show that digital technology has a promoting effect on industrial structure upgrading,and regional heterogeneity analysis shows that there is no significant differ-ence in the relationship between digital technology and industrial structure upgrading between resource-based and non-resource-based cities.Further analysis shows that the promotion of digital technology in the upgrading of indus-trial structure mainly stems from the application of digital technology.With the rise of the quantile position of indus-trial structure upgrading,the promoting effect of digital technology on industrial structure upgrading gradually in-creases,which makes the Beijing-Tianjin-Hebei region have the
