摘　　要：基于2003—2019年省域数据,构建互联网应用水平评价指标体系,并通过SYS-GMM模型、中介效应模型和调节效应模型,探讨互联网应用、技术创新、居民消费与产业结构优化四者之间的互动关系。研究发现:从整体来看,互联网应用对产业结构优化具有持续性正向促进作用;从中介效应来看,技术创新在互联网应用与产业结构优化的关系中存在显著的部分中介效应;从调节效应来看,居民消费在互联网应用与产业结构高度化的关系中存在显著的正向调节效应,而在消费与产业结构合理化之间无显著的调节作用。同时,技术创新的中介效应和居民消费的调节效应均存在明显的区域异质性,并伴随时段发展呈现增强趋势。Based on the provincial data from 2003 to 2019,the internet application level evaluation index system was constructed,and the relationship between internet application,technological innovation,resident consumption and industrial structure optimization was explored,through SYS-GMM model,mediating effect model and moderating effect model. The results show as follows. From the overall perspective,internet application has a continuous positive promotion effect on industrial structure optimization. From the intermediary effect, technological innovation plays a significant partial intermediary effect in the relationship between internet application and industrial structure optimization. From the moderating effect,there is a significant positive moderating effect of residential consumption on the relationship between internet application and industrial structure heightening,while there is no significant moderating effect on industrial structure rationalization. At the same time,the mediating effect of technological innovation and the moderating effect of residential consumption both have obvious regional heterogeneity,and tend to increase along with the time.
