help to improve the regional knowledge base. For a thorough judgement of our observa-
tions, these qualitative aspects of internal and external relations are crucial.
Notes
1. For an overview see Edquist (2004).
2. A detailed picture of the Jena innovation system is given in Graf (2006) and the role of intermediation and
political actors within the system is analysed in Cantner et al. (2008b) and Cantner et al. (2009).
3. For an overview of methods for creating networks from patent information see Breschi and Lissoni (2004).
For a more detailed description of our specii c application see Cantner and Graf (2006).
4. For further details on the dei nition and calculations of the various network measures, please refer to
Wassermann and Faust (1994).
