国家新一代人工智能创新发展试验区政策能否提升碳生产率?OACHSSCD

Artificial intelligence is an important force driving the improvement of energy efficiency and the precise management of carbon emissions,and achieving the goals of"carbon peak and carbon neutrality".Based on panel data from 31 provinces of China from 2013 to 2023,the national new generation artificial intel-ligence innovation and development pilot zones were used as quasi-natural experiments to construct a differ-ence-in-differences model so as to explore the impact effect and mechanism of artificial intelligence on carbon productivity.The study found:(1)The pilot artificial intelligence policy significantly has improved carbon pro-ductivity,and this conclusion remaines valid after a series of robustness tests.(2)From the perspective of the mechanism,artificial intelligence has enhanced carbon productivity by promoting innovation capabilities;an in-crease in the intensity of environmental regulations can positively moderate the promoting effect of artificial in-telligence on carbon productivity.(3)From the heterogeneity analysis,it can be known that the promoting effect of artificial intelligence on carbon productivity is more obvious on the southeast side of the Hu Huanyong Line and in highly digitalized areas.(4)The threshold test reveals that the industrial structure has a single threshold effect on carbon productivity.The threshold value is 1.425.When the industrial structure exceeds this threshold,the impact of artificial intelligence on carbon productivity is significantly positive.
