数字技术、经济效率与城市产业结构升级

Digital Technology,Economic Efficiency,and Urban Industrial Structure Upgrading

在分析数字技术发展对我国城市产业结构升级的影响机制基础上,采用2011—2021年276个城市的面板数据,构建数字技术发展指数,运用双重固定效应模型和中介效应模型实证检验数字技术对城市产业结构的影响。研究结果表明,数字技术能够显著推动城市产业结构升级,促进城市产业结构实现高级化;经济效率是数字技术推动城市产业结构升级的中介变量,数字技术通过降低交易成本、提升交易效率,以及深化劳动分工等途径提升经济效率,进而对城市产业结构升级进程形成间接促进效应;数字技术对城市产业结构升级的影响存在区域异质性,对于中西部等相对落后地区的城市产业结构实现向高端化的跨越发展具有重要的推动作用。据此,建议加强数字化基础设施建设,着力构建完善的数据要素市场,弥合区域间“数字鸿沟”,因地制宜制定产业数字化政策,加快数字技术与实体经济融合发展,以充分发挥数字技术对城市产业结构高级化的正向促进效应,推进城市产业结构升级。

Based on analyzing the impact mechanism of digital technology development on the upgrading of urban industrial structure in China,the panel data of 276 cities from 2011 to 2021 were used to build a digital technology development index,and the impact of digital technology on the urban industrial structure has been empirically tested using the dual fixed effect model and the intermediary effect model.The findings are as follows.Digital technology can significantly promote the upgrading of urban industrial structure and promote the advancement of urban industrial structure.Economic efficiency is an intermediary variable that digital technology promotes the upgrading of urban industrial structure.Digital technology improves economic efficiency by reducing transaction costs,improving transaction efficiency,and deepening labor division,thereby indirectly promoting the process of urban industrial structure upgrading.The impact of digital technology on the upgrading of urban industrial structure exhibits regional heterogeneity.It plays a crucial role in driving the transition towards high-end development in relatively less developed regions,such as the Midwest.Based on this,it is recommended to strengthen the construction of digital infrastructure,focus on building a complete data element market,bridge the“digital divide”between regions,formulate industrial digitalization policies tailored to local conditions,accelerate the integration and development of digital technology and the real economy,to fully leverage the positive promotion effect of digital technology on the upgrading of urban industrial structure and promote the upgrading of urban industrial structure.
