Regional innovation is sophisticated spatial system in which multi-bodies, dynamic mechanism and multi-spatial-levels exist. Its spatial structure is spatial organizing network consist of many basic nodes called as industrial clusters. Although Wuhan urban cluster boasts of abundant innovative resource, the linkages among the nodes are spatial loose and the resource mobility is slow. Thus the great "gap" appears between the core and the periphery in regional innovation capacity. One approach of the improvement in the spatial structure is to b...
