Clusters are considered sources of competitive advantage. A cluster is understood as a set of resources; however, it is noted that these resources vary according to their trajectory. Thus, this paper seeks to analyze the relationship between shared resources in the life cycle of the cluster. We conducted a cross-country study with two clusters in the footwear industry: Brazil and Italy. We present two main contributions. First, the competitiveness of clusters is sustained by their ability to renew and change their dependent trajectory. Second, we propose five elements that positively influence cluster competitiveness. These elements also help us understand the trajectory of clusters.
