The role of regional institutional entrepreneurs in the emergence of clusters in nanotechnologies

In the case of new technologies like nanotechnology, institutional entrepreneurs appear who have to act at different levels (organizational, regional, national) at the same time. We reconstruct, in some detail, the history of two cases, in Grenoble and in Twente/Netherlands. An intriguing finding is that institutional entrepreneurs build their environment before changing their institution. They first mobilize European support to convince local and national levels before actual cluster building occurs. Only later will there be reactions against any de-institutionalisation caused at the base location. The Dutch case shows another notable finding: when mobilizing support the entrepreneur will have to agree to further conditions, and then ends up in a different situation (a broad national consortium) than originally envisaged (the final cluster involved a collaboration of Twente with two other centres). In general, an institutional entrepreneur attempts to create momentum, and when this is achieved, he has to follow rather than lead it.
