The article regards innovation to be a universal factor in social structures self-organization.
The key identifying features of innovation are marked out. Innovation is: conjecturally constructive,
instrumental, complete, technological and reflective. Building on those features the author gives
operational definition of innovation. The paper proposes process-spatial approach to modeling
the innovation process synthesizing the theory of social self-organization and the social network
theory. A connection between the basic states of social systems functioning (LS and HS-modes
discovered by self-organization theory) and innovation process development is shown. LS-mode
is favorable for innovation formation and diffusion, while HS-mode is preferable for consolidating
established form of order. The most probable roles of various network structure types in innovation
process are identified.
