The concept of the Triple Bottom Line(TBL) has been emerged and employed in the field of event studies lately for evaluating impacts of an event or a festival. Recent TBL researches in event studies have been performed mostly within the context of economic, social and environmental aspects, eventually leading to the sustainability of a festival. However, the complexity of festival stakeholder`s diverse interest and concerns is closely linked with their different priority of festival impacts(economic, social and environmental), and further generates controversy among festival stakeholders. Thus it is vital, for producing sustainable festival, to understand the differences among festival stakeholders` value perception of the Triple Bottom Line. This paper highlights the differences of festival stakeholders` value perception of economic, social and environmental impacts. Stakeholders of festival organizers, host community and festival visitors at a mime festival were selected to response a total of 30 questions for TBL value perception. The result reveals that festival stakeholders have different perception on the value of economic, social and environmental impacts of a festival.
