Purpose – This paper aims to present a review of co-evolution practice in Host Partner Program of IndobuildTech Expo with system thinking approach that related to the current state of research. Design/methodology/approach – The paper presents a co-evolution model that relevance to the collaboration practice between exhibition organizer and visitors of IndoBuildTech Expo through Host Partner Program. Additionally, linking the co-evolution model in Host Partner Program that occurs with a system thinking construction through casual loop diagrams. The data collection method is a documentation study, by collecting written information, either in the form of research reports, media reports, and other documents related to the topic of writing. Furthermore, with a systems thinking framework, the author will carry out an analysis based on predetermined dimensions referring to the documentation study conducted. Findings – For the exhibition industry to generate lasting value, innovative concepts that take into account their capabilities and prospects are needed. One method is to implement synergy collaborations that leverage crossnetwork efforts to strengthen the exhibition business ecosystem. In this work, the co-evolution implementation process is carried out using the systems thinking methodology. It is the term used to advancements in collaboration between organizer and visitors. Co-evolution could improve the quality of visitors and elevate the perspective, contribution and role of visitors in the exhibition. Research limitations/implications – The concept of co-evolution with a systems thinking approach may not be widely used in the MICE sector at the moment. In order to address the needs of exhibitors and create a sustainable exhibition, it is envisioned that co-evolution with a systems thinking approach would lead to an increase in visitor quality and quantity. Studied co-evolution using a systems thinking approach in the exhibition industry are still in their early phases. The necessity for further co-creation research that more precisely articulates the modalities businesses can employ to progress towards co-creation is supported by this synthesis of earlier studies. Practical Implication – Co-evolution with this system thinking method seeks to increase the 'excellence service' of exhibition organizing activities and fulfill exhibitors' satisfaction for visitor quality and quantity to accomplish long-term IndoBuildTech show activities. R eferring to the strategic actions taken by Debindo-ITE on the system thinking process by identifying causal processes, as a result, the relationship between co-evolution and the systems thinking process approach is intertwined. Originiality/value – Studied co-evolution using a systems thinking approach in the exhibition industry are still in their early phases. The necessity for further co-creation research that more precisely articulates the modalities businesses can employ to progress towards co-creation is supported by this synthesis of earlier studies.
