How does artificial intelligence affect productivity and agglomeration? Evidence from China's listed enterprise data

In the digital economy era, artificial intelligence (AI) has advanced significantly and promoted productivity and productive service agglomeration. Using data on the productive service industry and AI in 27 provinces in China from 2006 to 2019, we investigated the influence of AI on productive services, and its direction and magnitude. We found that AI can promote the agglomeration of productive services directly or by enhancing productivity, and further analyzed the regional heterogeneity of the influence and mechanism.
