The tourism circuit court is a grassroots law enforcement tool for tourist destinations in China. This article constructs a multi-period difference-in-differences (DID) model to examine the impact of tourism circuit courts on tourism economic growth. Our findings reveal an 8.22% increase in economic growth within cities that have established a tourism circuit court. Furthermore, we develop a theoretical framework to explore the potential mechanisms originating from the judicial environment. This study confirms that judicial access, efficiency, and independence are key mechanisms by which tourism circuit courts affect economic growth. Our empirical results provide valuable insights into enhancing the quality of law enforcement within the tourism sector.
