The main aim of this article is to present and discuss the results of benchmarking research on Polish clusters in terms of the organizational and legal forms of their coordinators. These studies have been conducted systematically by the Polish Agency for Enterprise Development since 2010. Six editions of benchmarking studies conducted in 2010, 2012, 2014, 2018, 2020 and 2022 were subjected to comparative analysis. It allowed to identify the types of organizational and legal forms used by cluster coordinators in Poland, their diversity, and to show how the situation has changed over the years. There is no cluster institution in the Polish legal system. Cluster coordinators operate based on various legal forms. Over the past years, the dominant forms have been associations, foundations and commercial law companies – mainly limited liability companies. and joint-stock companies. Although individual analyses of the discussed scope can be found in the literature on the subject, they have not been conducted so far in such a comprehensive manner, covering nearly 15 years. The results of the work will constitute a starting point for further research related to the formal and legal aspect of cluster activities in Poland and the area of membership in cluster organizations.
