Abstract:In view of the problem of whether informatization, urbanization and industrial structure upgrading affect each other, based on the panel data of 31 provinces, autonomous regions and municipalities (not included Hong Kong, Macao and Taiwan) in China from 2005 to 2016, this paper constructs a panel vector autoregression model to study the dynamic relationship among informatization, urbanization and industrial structure upgrading. The results show that: the informatization, urbanization and industrial structure upgrading all have strong inertia; informatization and urbanization promote each other, and the influence of either party on the other is persistent; informatization has a long-lasting effect on industrial structure upgrading, while the promotion effect of industrial structure upgrading on informatization does not last long; urbanization plays a long-term role of promoting the industrial structure upgrading, but the industrial structure upgrading exerts an inhibitory effect on urbanization.
