ABSTRACT The population of recreation-seeking fishing tourists is increasing. This study aimed to examine the variables that contribute to predicting fishing tourists’ green behaviors at coastal tourism destinations by adopting an fsQCA approach. The research findings show that while each factor (i.e. perceived benefits, volitional variables, non-volitional variables, and emotion variables) individually exerts a significant influence on green behavior, the combined effect of integrating all these factors is substantial. This indicates that the synergy or combined influence of considering perceived benefits, volitional variables, non-volitional variables, and emotion variables together has a pronounced effect on promoting environmentally friendly behavior. Furthermore, the results of this study have academic and practical implications, as it was the first investigation of fishing tourists’ psychological mechanisms undertaken by defining the relationship between green behaviors and their antecedents.
