Abstract
This paper examines cluster policy from the perspective of cluster organisations. Cluster organisations are dedicated to enhancing the growth and competitiveness of selected clusters, and do so by engaging in a wide range of activities. Using survey data from a large number of cluster organisations in many different countries, these activities are shown to fall into seven distinct groups. The effect of each upon self-reported performance is assessed and found to vary between activity groups. In addition, the performance effect of cluster organisations initiated by government or undertaken in collaboration with other cluster organisations is tested, but no evidence is found to support the assumption that these factors have an effect in general.
