A total of 1020 valid questionnaires were collected from tourists in Lukang Town, Taiwan, by means of convenient sampling. After descriptive statistics and PLS statistical analysis, the results show that: 1) Tourists’ image of Lukang town has a positive effect on their perceived service quality. In addition, it also has a positive effect on future travel behavior intention;2) The service quality of tourists in Lukang has a positive effect on their future travel behavior intention. 3) This study also finds that service quality has a mediating effect on tourism behavior intention. Finally, based on the results of the study, suggestions for future research and tourism planning are put forward.展开更多
