With the booming development of new generation information technology,digital economy is undoubtedly an inevi-table choice to achieve new urbanization.Based on the panel data of 30 provinces(municipalities,cities)from 2013 to 2022,this paper studies the impact of digital economy on new urbanization by constructing the index of digital economy development level and the index of new urbanization level,and introduces technological innovation and carbon emission reduction to analyze the mechanism of new urbanization driven by digital economy.The study finds that the digital economy has an obvious promotion effect on the con-struction of new urbanization in China,and the provinces with low level of new urbanization and the central region have a more ob-vious promotion effect;the mechanism analysis shows that technological innovation and carbon emission reduction are the important conduction mechanisms of the digital economy to promote the new urbanization;through further threshold test,it is found that the promotion effect of the digital economy on new urbanization shows a positive and then negative characteristic due to the continuous upgrading of the industrial structure.Through further threshold test,it is found that the driving effect of digital economy on new ur-banization is positive and then negative due to the continuous upgrading of industrial structure.The findings of the study can provide empirical evidence and policy insights for accelerating the release of digital economy dividends and promoting the development of new urbanization.
