The construction of information infrastructure as well as the transformation and upgrading of the industrial structure are among the major challenges for the Chinese economy. Therefore, it is of great significance to explore how information infrastructure affects the upgrading of industrial structure. Based on the panel data of 31 provinces in China from 2013 to 2020, mediating effect model and non-parametric percentile bootstrap method are used to carry out empirical research, by creating an information infrastructure construction level and industrial structure upgrading indicators. The results show that, in addition to the direct effect of information infrastructure on industrial structure upgrading, information infrastructure can also work indirectly through three paths: (1) information infrastructure acts on industrial structure upgrading by enhancing urbanization level; (2) information infrastructure affects industrial structure upgrading by boosting technological innovation; (3) information infrastructure first enhances urbanization level, then acts on technological innovation, and finally promotes industrial structure upgrading. In addition, the intermediary effect of technological innovation is stronger than urbanization. In general, this study acknowledges that urbanization and technological innovation are partial mediators in the process of information infrastructure affecting industrial structure upgrading, notwithstanding other potential impact pathways being studied further.
信息基础设施建设以及产业结构转型升级是中国经济面临的主要挑战之一。因此，探讨信息基础设施如何影响产业结构升级具有重要意义。本文基于 2013-2020 年中国 31 个省份的面板数据，运用中介效应模型和非参数百分位 bootstrap 方法，通过构建信息基础设施建设水平和产业结构升级指标进行实证研究。结果表明，信息基础设施对产业结构升级不仅有直接效应，还可以通过三条路径间接作用：（1）信息基础设施通过提高城市化水平作用于产业结构升级；（2）信息基础设施通过促进技术创新影响产业结构升级；（3）信息基础设施首先提升城市化水平，继而作用于技术创新，最终推动产业结构升级。此外，技术创新的中介效应强于城市化。总的来说，本研究承认，在信息基础设施影响产业结构升级的过程中，城市化和技术创新是部分中介变量，尽管其他潜在的影响途径仍在进一步研究中。
