In Berlin there exist four hotspots of Cis, three of these are also artists districts. Every
hotspot has its own urban milieus including breeding grounds. There not only exists a
spatial concentration but also a coherence between density of CIs and artists in ZIP-
code areas in Berlin (hypothesis 3).
To be creative and gain experience, artists and agents in CIs need open spaces
without the pressure of commercial land use (hypothesis 4).
The linkage microstructure of agents will be more close meshed outwards, more
completed and consequently also the access to tacit knowledge is more difficult.
If the market position is too strong for the client, it is possible to overcome the barrier
of socio-economic bounding and to leave the milieu.
If firms do so, they take along their social and value-chain related relation to the new
location.
Thus not all explaining variables enter the econometric modelling, as the case may be
unknown or only on the administrative level of Berlin’s district available, the
heterogeneity of represented different actor groups has become clear and points at
certain trends of different reasons for settlement in parts of Berlin and corresponding
milieus. Despite complex regional-economic effects, potential synergy effects,
originating from the co-operation with other industries and an increasing absorption
of artists and cultural values in the production of services and products, visual artists
have a difficult economic situation to master. Although they decisively initiate and
promote innovative processes in value added chains, the discussion on the challenge
of artists and their contribution to the economy as a whole is hushed.
