Research on the Impact of Innovation Policies on the Transformation and Upgrading of Industrial Structure:Empirical Analysis Based on National Independent Innovation Demonstration Zones
Based on panel data from 283 cities in China from 2004 to 2019,this article uses a progressive double difference model to evaluate the impact of national independent innovation demonstration zones on industrial transformation and upgrading.Research has found that the establishment of national self created zones can significantly promote the upgrading and rationalization of industrial structure,there-by effectively promoting the transformation and upgrading of industrial structure.In terms of impact mechanisms,the effects of resource allocation and technological innovation can significantly promote the upgrading of industrial structure,but they have not effectively promoted the rationalization of in-dustrial structure.The government support effect can simultaneously promote the upgrading and ra-tionalization of industrial structure.In addition,the promoting effect of national self created zones on the transformation and upgrading of industrial structure has obvious regional heterogeneity.Based on the research findings,the article suggests further leveraging the external regulatory role of national self created zones in factors such as capital and labor,increasing technological innovation and government support,and exploring differentiated and distinctive development models of national self created zones based on regional characteristics.
