The Network Mechanism and Evolution Paths of Technology Innovation in Industrial Cluster

From the multiple network theory,the different roles of manufacturing network and RD network to process innovation and production innovation are analyzed,and the intrinsic relationship between the evolution of network system and cluster innovation is explored.Research findings are showed in the following:(1) Manufacturing network promotes process innovation of cluster,while RD network is an important enabler of product innovation of cluster.(2) The evolution of cluster technology innovation is along the upgrade of manufacturing network,the expansion of RD network,the upgrade of RD network,and the expansion of manufacturing network.
