Abstract: In the era of the digital economy, data elements are the premise and foundation of the development of the artificial intelligence industry. Taking the national big data in comprehensive pilot zone as an example, based on the panel data of 281 prefecture-level cities in China from 2008 to 2022, this paper analyzes the influence effect and related mechanism of data element agglomeration on the development of the artificial intelligence industry through multi-stage difference-in-differences model and dual machine learning model. The study finds that data element aggregation can promote technological innovation and scale expansion of the artificial intelligence industry, which is supported by a variety of robustness tests. The mechanism test finds that data element agglomeration mainly realizes the development of the artificial intelligence industry by promoting the agglomeration of innovative talents and improving the urban business environment. The results of the heterogeneity test show that the impact of data element agglomeration on the artificial intelligence industry is more significant in the southeast side of Hu Huanyong Line (Heihe-Tengchong Line) and in the regions with higher education level and industrial development level. The dynamic effect test results find that the empowering effect of data element agglomeration on the development of the artificial intelligence industry will gradually increase over time. The above conclusions provide a theoretical basis and scientific reference for the effective utilization of data resources and the high-quality development of the artificial intelligence industry.
