Extant studies have increasingly investigated the impact of tour guide humor on tourist responses but paid insufficient attention to its effect on tourist pro-environmental behavior. Following the conservation of resources theory, this research examined how tour guide humor influences tourist pro-environmental behavior by identifying tourist relational energy as the mediator and tourist self-construal as the moderator. The theoretical model was tested using data from 476 tourist-matched surveys nested in 28 tour groups. Tour guide humor can stimulate tourists’ perception of relational energy and further motivate tourists to engage in pro-environmental behavior. Tourists’ self-construal can moderate the effect of tour guide humor on relational energy and the indirect effect of tour guide humor on tourist pro-environmental behavior via relational energy. Specifically, the positive association between tour guide humor and relational energy is stronger for tourists with more interdependent self-construal than for those with more independent self-construal. This study contributes to the tourist pro-environmental behavior literature by identifying tour guide humor as a prominent determinant. Valuable recommendations are also provided for destination management organizations to promote tourist pro-environmental behavior from the perspective of tour guide humor.

现有的研究越来越多地研究导游幽默对游客反应的影响，但对其对游客亲环境行为的影响关注不足。本研究遵循资源节约理论，通过将游客关系能量作为中介，游客自我建构作为中介，考察导游幽默如何影响游客的环保行为。该理论模型使用来自 28 个旅游团的 476 个旅游匹配调查的数据进行了测试。导游幽默可以激发游客对关系能量的感知，进一步激发游客参与环保行为。旅游者的自我建构可以通过关系能量调节导游幽默对关系能量的影响以及导游幽默对旅游者亲环境行为的间接影响。具体而言，对于具有更多相互依赖的自我构念的游客来说，导游幽默与关系能量之间的正相关关系比那些具有更多独立自我构想的游客更强。这项研究通过将导游幽默确定为一个突出的决定因素，为旅游亲环境行为文献做出了贡献。还为目的地管理组织从导游幽默的角度促进游客的环保行为提供了有价值的建议。导游幽默与关系能量之间的正相关关系对于具有更多相互依赖的自我构念的游客来说比那些具有更高的独立自我构想的游客更强。这项研究通过将导游幽默确定为一个突出的决定因素，为旅游亲环境行为文献做出了贡献。还为目的地管理组织从导游幽默的角度促进游客的环保行为提供了有价值的建议。导游幽默与关系能量之间的正相关关系对于具有更多相互依赖的自我构念的游客来说比那些具有更高的独立自我构想的游客更强。这项研究通过将导游幽默确定为一个突出的决定因素，为旅游亲环境行为文献做出了贡献。还为目的地管理组织从导游幽默的角度促进游客的环保行为提供了有价值的建议。
