This work sets up a research model that elaborates upon the development of continuance intention towards Mobile Travel Service System (MTSS) based on the motivational theory and the dependency theory. In the model, continuance intention is indirectly affected by personal innovativeness and e-interaction quality through the full mediation of e-engagement and perceived enjoyment. At the same time, the relationships between e-engagement and continuance intention and between perceived enjoyment and continuance intention are hypothetically moderated by e-interaction quality. The hypotheses of this work were empirically tested using data from working professionals in a technology industry regarding their use of MTSS for travel information sharing as well as booking for accommodation, airline, cars, etc. This study conducted a two-wave survey to empirically test its theoretical rationales. The findings of this work complement the previous literature by verifying the full mediating mechanism of e-engagement and perceived enjoyment and the moderating mechanism of e-interaction quality. Lastly, managerial implications for e-marketers based on this study’s findings are provided.
