The purpose of this study is to evaluate the understanding of participation value of the exhibition among the constituent entities, and to draw implications from the unique concomitance that an exhibition can construct. For the three major constituent entities of the exhibition, agreement, congruence, accuracy, and meta-agreement, which are the measuring elements of co-orientation model, are analyzed, and the economic value, symbolic value, cognitive value, social relational value, educational value, and inherent value of the exhibition are analyzed. A total of 444 people, including 129 organizers, 142 exhibitors, and 173 visitors, responded effectively to the survey. According to the analysis, the co-orientation among the three entities cannot be said to be very high. The academic significance of this study is mainly to find out the intrinsic and extrinsic meaning of the exhibition and to highlight the importance of communication through the co-orientation model among the entities of the exhibition.
