【摘要】 我国的产业结构亟须升级优化.选取2011年到2019年我国31个省的面板数据，借助固定效应模型研究基础设施建设对产业结构升级的影响，并采用基础设施建设水平的一阶滞后项作为工具变量进行内生性检验，结果发现：无论是新基建设还是传统基建均对产业结构升级有着显著促进作用，工具变量的回归结果与基准回归结果基本一致；外商投资是基础设施影响产业结构升级的路径；基础设施对产业结构升级的影响存在门槛效应.更多还原

【Abstract】 China’s industrial structure is in dire need of upgrading and optimization. Panel data of 31 provinces in China from 2011 to 2019 are selected to study the impact of infrastructure construction on the upgrading of industrial structure with the help of fixed effect model, and the first-order lag term of infrastructure construction level is used as a tool variable to conduct the endogeneity test. The results show that: Both the new infrastructure construction and the traditional infrastructure construction play a significant role in promoting the upgrading of industrial structure, and the regression results of instrumental variables are basically in consistency with the baseline regression results. The results show that foreign investment is the path that infrastructure affects the upgrading of industrial structure. Infrastructure has threshold effect on industrial structure upgrading.更多还原
