In the context of global efforts to curb CO 2 emissions, identifying new drivers of low-carbon transition has become a pressing task for countries worldwide. However, whether tourism development acts as a catalyst for this transition remains unclear. To address this gap, our study adopted carbon emission efficiency as an indicator to better capture the dynamics of the low-carbon transition. Employing a dynamic SYS-GMM model, this study explored the potential inverted U-shaped relationship between tourism development and low-carbon transition. Moreover, recognizing the growing influence of the ...
