Intensified law enforcement and firm innovation: Evidence from China's antitrust consolidation

This paper examines the significant transformation in China's antitrust regulatory framework following the consolidation of its three primary antitrust agencies the Ministry of Commerce (MOFCOM), the National Development and Reform Commission (NDRC), and the State Administration for Industry & Commerce (SAIC) into the State Administration for Market Supervision (SAMR). Utilizing data from publicly listed firms across various industries, we analyze how firms in highly concentrated industries have adapted to this consolidation, by increasing the R&D investment, patent filing, and total factor productivity (TFP). Our mechanism channel indicates that stricter enforcement actions and fines by SAMR have spurred competition and innovation, with effects that are comparably significant across both state-owned enterprises (SOEs) and private firms. The paper contributes to the literature by providing an empirical assessment of the effects of this major restructuring within China's Anti-Monopoly Law (AML) enforcement. Our findings shed light on the broader implications of regulatory consolidations on firm innovation, offering insights into the efficacy of such transformations in antitrust policy.
