‘Public research-led cluster’ might be more to the point, as it appears difficult to judge if these are more or less ‘intellectual’ than other forms of clusters.
‘initial conditions’ fail to capture the complexity of clusters if they are reduced to a dichotomy of private vs. public sector dominance. Even when the industry (biotechnology) is held constant, clusters differ in a number of ways, esp. regarding their specialisation within biotechnology, their maturity, size (number of firms and employee) and firm size structure.
