The tourism economy is regarded as an effective way to realize regional sustainable development. Hence, it is of great significance to explore whether and how tourism economy can alleviate regional carbon emission intensity. To this end, a structural equation model (SEM) reflecting the multiple pathways of the carbon emission reduction effect of tourism economy was constructed based on 92 tourism-dependent cities in China, and the existence and formation mechanism of the carbon emission reduction effect of tourism economy were empirically tested. The main findings are as follows: (1) The tourism economy has a significant carbon emission reduction effect in China. Although the direct impact of tourism economy on carbon emission intensity is significantly positive, the indirect impact is significantly negative and stronger than the direct impact. (2) The carbon emission reduction effect of tourism economy presents multiple pathways characteristics. There are single intermediary pathways such as Tourism Economy → Environmental Regulation → Carbon Emission Intensity, Tourism Economy → Opening-Up → Carbon Emission Intensity, and dual intermediary pathways such as Tourism Economy → Opening-Up → Industrial Development → Carbon Emission Intensity, Tourism Economy → Opening-Up → Innovation Capacity → Carbon Emission Intensity. (3) The formation mechanism of the carbon emission reduction effect of tourism economy presents obvious spatial heterogeneity.
旅游业经济被视为实现区域可持续发展的有效途径。因此，探讨旅游业经济是否以及如何能够减轻区域碳排放强度具有重要意义。为此，本文基于中国 92 个旅游依赖型城市，构建了一个反映旅游业经济减排效应的多路径结构方程模型（SEM），并实证检验了旅游业经济减排效应的存在性及其形成机制。主要研究结果如下：（1）旅游业经济在中国具有显著的减排效应。尽管旅游业经济对碳排放强度的直接影响显著为正，但间接影响显著为负且强于直接影响。（2）旅游业经济的减排效应呈现出多种路径特征。存在单一中介路径，如旅游业经济→环境规制→碳排放强度、旅游业经济→开放程度→碳排放强度，以及双重中介路径，如旅游业经济→开放程度→产业发展→碳排放强度、旅游业经济→开放程度→创新能力→碳排放强度。（3）旅游业经济减排效应的形成机制呈现出明显的空间异质性。
