| Abstract: | Knowledge network is a kind of inter-connected network that is born in the process of diffusion and communication of knowledge by the actors who create,transfer,absorb and apply knowledge,such as enterprises,universities,organizations and institutions.Network structures may exert influence on the actors and regions involved,and the potential for successful knowledge absorption and learning may be partly determined by network positions.Up to present,there are no researches about the evolution of spatial stru... |
