Extant research indicates that temporary clusters, such as trade fairs and exhibitions, play a significant role in knowledge dissemination and innovation by creating global buzz, so they are beneficial to building global pipelines. However, these findings are mainly based on the experiences in the manufacturing sectors of developed countries. This paper, however, chooses Beijing as a case to examine whether or not international exhibitions in creative industries contribute to innovation in emerging economies. Based on questionnaire surveys and semi-structured interviews conducted in 2015–2016, this paper uses a structural equation model (SEM), with three latent variables related to global buzz, global pipelines, and information acquisition, to identify the internal patterns of exhibition innovation. The results indicate that there exists innovation generated from temporary clusters in knowledge-intensive sectors as well as emerging economies. Global buzz and global pipelines construct a favorable interaction ecology. However, global buzz plays a greater role than global pipelines. This insight should help organizers improve creative exhibitions in terms of innovation and provide a deeper understanding of the relationships between innovation, global buzz, and global pipelines in temporary clusters.
