The fluidity of inventor networks
- 11 Downloads
We investigate the ‘fluidity’, i.e., entry and exit of inventors, as well as changes of their relationships in nine German regions. The levels of entry and exit of inventors are rather high and most links among inventors are only short term. Fluidity of inventors and links leads to some fragmentation of the regional inventor networks but does not significantly affect other network characteristics. Entry of new inventors and growing numbers of links are positively related to the performance of the respective regional innovation system.
