Cluster Life Cycles - Dimensions and Rationales of Cluster Development

We present a model that explains how a cluster moves through a life cycle and why this movement differs from the industry life cycle. The model is based on three key processes: the changing heterogeneity in the cluster describes the movement of the cluster through the life cycle; the geographical absorptive capacity enables clustered companies to take advantage of a larger diversity of knowledge and the stronger convergence of clustered companies compared to non-clustered companies results in a reduction of heterogeneity. We apply these processes to four stages of the cluster life cycle: emergence, growth, sustainment and decline. JEL-classification: R11, O30, L25
