This study examines the impact of cultural and tourism integration on green total factor productivity in China, utilizing provincial panel data from 2010 to 2021 and employing both static panel models and system GMM models. The findings reveal a nonlinear "U-shaped" relationship, where culture and tourism integration initially suppresses but ultimately enhances green total factor productivity, contingent upon achieving a preliminary level of coordination. Regional analysis shows that this "U-shaped"relationship is present only in the highly integrated eastern regions. Additionally, market environment and industrial agglomeration significantly moderate the relationship between culture and tourism integration and green total factor productivity. The advanced industrial structure emerges as the ultimate pathway through which culture and tourism integration fosters improvements in green total factor productivity. Based on these insights, targeted recommendations are proposed to promote culture and tourism integration, thereby empowering green total factor productivity.
