Accelerating the transition of energy structure to renewable energy is the key path to carbon peak and carbon neutrality,and digital economy,as a new engine for high-quality economic develop-ment,and the innovation and development of its core industries are crucial for realizing carbon emission reduction in the energy sector.Relying on China's inter-provincial data from 2010 to 2020,this paper analyzes in-depth the mechanism of digital technological innovation in reducing carbon emissions,and examines the impact of energy structure,green finance and the level of financial deepening.The study shows that digital technological innovation has a significant inhibiting effect on carbon emissions,energy consumption structure plays an intermediary role in reducing carbon emissions by digital technological innovation,and green finance plays a moderating role,both of which jointly promote emission reduc-tion.The level of financial deepening has a negative single-threshold effect in the process of pollution reduction and carbon reduction by digital technological innovation,and there is regional heterogeneity in the impact of digital technological innovation on carbon emissions.Therefore,it is necessary to accel-erate the pace of digital technological innovation,promote the transformation of energy structure to re-newable energy,promote green financial practices,and formulate differentiated emission reduction poli-cies for regional differences,so as to effectively promote the realization of national and regional carbon emission reduction targets.
