Abstract: In response to the arguments such as "geography is dead" and "geography is no longer important", economic geography scholars rediscovered the significance of geography through exploring the relation between innovation and geographic space. Innovation interaction studies suggest, only geographical
proximity does not promote regional innovation. Besides geographic proximity, innovation also needs organization proximity and cognitive proximity. To
innovation, geographical space is no longer a simple physical distance, but also includes other multi-dimensional space, such as organization proximity
and cognitive proximity. Although physical proximity is neither sufficient condition nor necessary condition to promote innovation, geographical proximity
still is of importance to innovation because geographic agglomeration can promote cognitive proximity and organization proximity. Although empirical
studies found that there is relation between geographic proximity and innovation performance, it is not clear which proximity has promoted the innovation
performance. The research on the relations of various proximity and innovation is still in the theoretical construction stage, it is urgently to develop relevant
empirical research.
