Abstract
An extensive body of research examines concentration levels (i.e., “mass”) of industry clusters; however, little attention is paid to their dynamics (i.e., “motion”). Understanding cluster dynamics is important because how clusters change over time may have implications for firm strategies and outcomes that are not attributable to cluster mass alone. To advance scholarship, we derive a theoretically grounded measure of cluster motion. Applying this measure to data on establishments in the U.S. computer and semiconductor industries, we document the dynamic nature of clusters both within and across regions. We demonstrate that our measure of cluster motion is distinct from cluster mass. Furthermore, we document that regions rarely follow stylized descriptions of cluster life cycles, which underscores the importance of measuring and investigating cluster dynamics.
