In theory,the development of the digital economy promotes industrial structure transformation and upgrading by influencing inter-industry structural transformation,improving intra-industry labor productivity,and boosting industrial resource allocation efficiency.This paper takes the data of 247 cities at prefecture level and above in China from 2016 to 2019 as an exam-ple to analyze the impact of digital economy development on industrial structure transformation and upgrading by using a fixed ef-fect model.The empirical results show that the development of digital economy has a significant promoting effect on the transfor-mation and upgrading of industrial structure in the first,second,and third dimensions,that the empirical results of sub-sample da-ta and the adoption of alternative variables support this research conclusion,and that after controlling the endogeneity,the re-search conclusion still holds.Further mechanism test reveals that the development of digital economy mainly promotes industrial structure transformation and upgrading through two channels:consumption upgrading effect and technology spillover effect.
