Special interest is paid to the economic performance of regional clusters in the Polish economy. The main research questions are: what characterizes the regional clusters in Poland and what are the main tendencies in cluster development? The purpose of this research is to analyse the importance of clusters and their influence on employment growth. The analysis is based on the theoretical framework of the cluster development and experiences in some old and new EU Member States. The research shows that clusters in EU 27 and Poland differ in many dimensions: the point at which they arise, the type of products and services they offer, their stage of development, and the business environment that surrounds them.
