Abstract:Artificial intelligence technology innovation is the key engine to achieve the "dual carbon" goal. Based on panel data from 30 provinces in China from 2011 to 2021, this paper examines the impact of AI technology innovation on carbon emission intensity in multiple dimensions. The results show that AI technology innovation significantly reduces carbon emission intensity, which is still true after a series of endogenous and robustness tests. Mechanism analysis shows that AI technology innovation mainly indirectly promotes carbon emission reduction through improving energy efficiency, and the advanced industrial structure, marketization level and factor resource misallocation level are the key factors affecting the energy efficiency improvement of AI technology innovation. The analysis of regional heterogeneity shows that artificial intelligence technology innovation only has a significant inhibitory effect on carbon emissions in the eastern region, and the central and western regions do not produce obvious carbon emission reduction effects, but accelerate the carbon emissions in the western region. Spatial econometric analysis shows that AI technology innovation can not only reduce the carbon emission intensity of local but also the carbon emission intensity of neighboring areas, which is conducive to forming a spatial pattern of coordinated development of regional green innovation. In addition, the impact of artificial intelligence technology innovation on carbon emissions also has a significant "rebound" effect. The research conclusion provides a feasible path to help the "dual carbon" goal, and also provides new empirical evidence for local government departments to actively plan and promote artificial intelligence technology innovation solutions.
