Building on the approach on Neck et al. (2004) on entrepreneurial systems, on recent developments on Business Models and Ecosystems (Clarysse et al., 2014; Atour and Bulger-Helchem, 2014; Autio et al., 2014) within coevolutionary approaches (Mack and Mayer, 2015), this research analyses both the emergence and consolidation of an entrepreneurial ecosystem and of its associated coopetitive business models. The field study has been conducted in the wine cider industry in Quebec (Canada) where there has been an exponential growth with new firms and SME rejuvenation since the eighties.
