Abstract:Abstract: Based on Chinese provincial panel data from 2007-2019, this paper investigates the impact of local government economic competition, ecological competition, and service competition on upgrading industrial structure by using the Fixed-effect model method .Moreover, the paper explores the impact of the interaction between heterogeneous local government competition on upgrading industrial structure by using the moderated mediation model that green technology innovation as moderating variable . The results show that: (1) there are significant differences in the effects of heterogeneous government competition on upgrading industrial structure. Among them, economic competition has a significant inhibitory effect on upgrading industrial structure, and ecological competition and service competition have a significant facilitating effect onupgrading industrial structure. The robustness test results show that the regression results are reliable.(2) The intermediary effect result show that “Local government competition f- green technological innovation- upgrading industrial structure” transmission mechanism. Economic Competition inhibits the innovation of green technology, indirectly inhibits the upgrading of industrial structure.Ecological competition and service competition indirectly promote the upgrading industrial structure by improving green technology innovation.
