Study title: THE EFFECT AND MECHANISM OF ARTIFICIAL INTELLIGENCE APPLICATIONS ON ENTERPRISE MARKET POWER IN CHINA

A study of China's A-share listed companies between 2006 and 2024 treated the creation of national new-generation AI innovation pilot zones as a quasi-natural experiment. Using a staggered difference-in-differences model, it found the zones had a positive causal effect on firm markups, the gap between price and cost that indicates market power.

This study employs the establishment of China’s national new-generation AI innovation pilot zones as a quasi-natural experiment. Using data from A-share listed companies between 2006 and 2024, it conducts a systematic examination using a staggered difference-in-differences model. Our estimates indicate a robust positive causal effect of AI pilot zones on firm markups. Mechanism tests suggest that the policy works primarily through talent agglomeration and innovation incentives. Heterogeneity analysis indicates t…

The gain

A difference-in-differences study of China's A-share listed companies from 2006 to 2024 found that locating in a national AI innovation pilot zone raised firm markups, mainly through talent agglomeration and innovation incentives.

In brief

The effect ran mainly through talent agglomeration and innovation incentives. It was stronger for manufacturers, private enterprises, high-tech firms and companies in eastern regions, so the gains were unevenly spread across firm types and geography.

The authors recommend strengthening regional coordination to bridge the digital divide, helping firms adopt AI strategies suited to their context, and refining competition policy to balance innovation incentives with market fairness. That last point reflects a concern that higher markups can mean more market power.

Main points

  1. The study used the rollout of China's national new-generation AI innovation pilot zones as a quasi-natural experiment.
  2. It analysed A-share listed companies from 2006 to 2024 with a staggered difference-in-differences model.
  3. The pilot zones had a positive causal effect on firm markups.
  4. Mechanism tests point to talent agglomeration and innovation incentives as the main channels.
  5. The effect was more pronounced in manufacturing, private enterprises, high-tech firms and eastern regions.
  6. Case studies identified three AI pathways: technology-driven adoption, manufacturing-service integration and data-driven product innovation.

The full story

The researchers used the staggered creation of China's national new-generation AI innovation pilot zones to compare listed firms before and after the policy. Their data cover A-share listed companies over 2006 to 2024, which allowed a long pre-policy baseline.

The mechanism tests suggest the policy works mainly by drawing talent into the zones and strengthening incentives to innovate. Heterogeneity analysis found stronger effects for manufacturing, private enterprises, high-tech firms and firms in eastern regions.

Case studies describe three ways firms apply AI: technology-driven adoption, manufacturing-service integration and data-driven product innovation. The authors call for regional coordination to narrow the digital divide, tailored adoption strategies, and a competition policy framework that balances innovation incentives with market fairness.
