Abstract

To sustain economic growth, countries have to manage systems in order to create technological innovation. To meet this goal, they are developing policies that organically connect companies, national laboratories, and universities into innovation networks. However, the whole structures of these connections have been little investigated because of the difficulty of obtaining such data.
