Recently, technology changes faster and faster, and product life circle turn short sharply. The innovation cost and market and technology risk are huger and huger. Multi-subjects integration is the new trend for innovation. For breaking through the limit of self-resource and capability, single corporate is looking for cooperation from external organizations in innovation activities. More and more innovation activities are one important tactic to improve corporation's core competitive power.Before cooperation innovation research focused on the system factor comparatively, i.e. the network which is formed of mutual influence between innovation activity, system factor and all organizations; Now the research focuses on the interaction between organizations, i.e. the network which is formed of all organizations surrounding the innovation activities. Wholly, the frame which integrates and analyzes the two networks is not built. The interface research of technology innovation is narrow and discrete without integrating all interfaces comprehensively. |
