The European Clusters Alliance (ECA) is the common voice for European clusters, which account for almost 61.8 million jobs across the different countries. The association joins 15 national associations of clusters and more than 800 clusters organisations on European level. These make up for 123,000 of our most innovative businesses and over 10,000 universities, research centres, and public institutions. Furthermore, ECA has representatives from Italy, Ireland, and Greece – countries without national clusters networks – who serve as ambassadors. Why is an European alliance of clusters needed?...
