TWO-LAYER MODEL OF INNOVATION NETWORK
The article examines the economic nature of the structure of innovation network. It is proposed to allocate two levels of innovation networks: the level of the artifacts and the level of the network actors. The nature of the relationship between the levels of the network is determined by the nature of the «hard» and «soft» innovation infrastructure: the «hard» one is the artifacts, and the «soft» one aims to link the network levels.
