Abstract Technological innovation is the internal driving force to promote the transformation and upgrading of industrial structure.Based on the panel data of prefecture-level cities in the Yangtze river economic belt from 2007 to 2017, this paper adopts the panel Tobit regression method and threshold effect analysis method to investigate the influence mechanism of regional technology innovation on industrial structure upgrading under the effect of marketization regulation.The results show that regional technological innovation can effectively promote the rationalization and development of industrial structure, and the driving force becomes stronger and more significant after the introduction of marketization.Further research shows that such a regulating effect also shows threshold effect in the rationalization of industrial structure.In the sectional analysis, the regulating effect is relatively strong in the upstream and mid-stream cities, but relatively weak in the downstream cities.Therefore, it is suggested that regional development heterogeneity should be emphasized and an optimal market environment should be constructed to support regional innovation's role in promoting industrial structure transformation and upgrading.
