Firms that are located in a cluster may confront cooperation and competition at the same time. The advantage of cooperation and the disadvantage of competition on a firm may need to examine the firm survival in a cluster as the cluster evolves. Employing the population ecology viewpoint, this study tries to address coopetition issues in a cluster to examine the impact of coopetition on firm survival rate. Analyzing yacht industry data in Taiwan from 1957–2010, this study indicates that the founding rate of yacht firms will be positively related with the cluster size. Additionally, during the competition period, those firms located inside the cluster may have a higher dissolution rate than those firms outside the cluster, indicating the disadvantage of competition on the firm. Finally, this study finds that those firms located inside the cluster will be more likely to become larger and have capabilities to survive. The results in this study provide insights on addressing coopetition issues in a cluster.
