The Influence of the National Integrated Circuit Industry Investment Fund on the Innovation Performance of Artificial Intelligence Chip Industry in China
Based on the patent data of AI chips in 268 cities in China from 2008 to 2021,this paper takes the National Integrated Circuit Industry Investment Fund as a quasi-natural experiment.It empirically analyzes the influence and mechanism of the National Integrated Circuit Industry Investment Fund on the innovation performance of the AI chip industry by using the multiphase difference-in-differences model.It is found that the National Foundation can significantly improve the quantity and quality of technological innovation of AI chips,and the guiding effect is an important mechanism for the National Integrated Circuit Industry Investment Fund to promote the innovation performance of the AI chip industry.The influence of the National Integrated Circuit Industry Investment Fund on the innovation performance of the AI chip industry is heterogeneous,and it has a better promotion effect on the downstream of the industrial chain,the eastern region,high-grade cities,and cities with good innovation environments.
