Abstract:Equipment manufacture, which is shown as knowledge intense, reflects the intersection and integration of high, fine and sharp technology in multidisciplinary and multi-domain and needs to achieve technological innovation by acquiring and integrating external knowledge. The process of innovation integration is impacted by knowledge characteristic and network structure. This paper studies on the innovation integration of equipment manufacturing enterprise through the structural equation modeling. And the results indicate that intellectual property can not only directly affect the enterprise technology innovation, but also indirectly affect the technological innovation through the network; the network environment has direct positive effect on technological innovation, and ties of network connection play a role in promoting innovation performance through the network environment.
