This study aimed to derive future development plans for the Korean International Ceramic Biennale held in Gyeonggi-do through a qualitative research method focusing on sustainable growth. In-depth interviews were conducted with eight experts closely related to ceramic arts, including scholars specializing in ceramic art and judges of the biennale. Due to the study being conducted during the COVID-19 era, experts voluntarily visited the biennale site during the event period, completed on-site monitoring, and initially submitted written interviews. Subsequently, in-depth opinions were obtained through telephone interviews. The specific items for the expert survey included event planning, related organizations/personnel, exhibition operations, public relations and participation, and online platform operations. As for the future direction of event development, it encompassed event planning and program competitiveness, event scale expansion and globalization, and organizational promotion. Additionally, the interview items were designed to enable an in-depth collection of opinions through benchmarking cases and suggestions. As a result of the study, four major themes and nine subcategories were derived for the biennale’s future development plan. The four themes derived were: ‘loss and crisis of indicators of ceramic art’, ‘absence of continuous promotion and marketing’, ‘expansion of online platforms’, and ‘utilization as a medium for revitalizing city tourism’. Through the results of this study, it was possible to confirm the direction to be pursued and to restore the role as a biennale to strengthen competitiveness in the future.
