The article is aimed at discussing the unique characteristics of the “triple helix” model that are unveiled while applied to cross - border cluster studies. The results of the case study method of the best practice on cross - border cluster formation at the Baltic Sea region shows evidence of the doubling of the number of helices represented in a complex collaboration system. Major factors of the dynamics and the transformation of the cross-border cluster interactions are stated. The hypothesis of the “double triple helix” model is suggested and the illustration of the case study example of the “Medicon Valley” is given.
