As China's high-speed rail has been widely recognized in the world market, China's high-speed rail technology innovation has attracted worldwide attention. The success of China's high-speed rail technology innovation has become consensus among all walks of life. Combined with the practice of technological innovation Chinese high-speed, based on the theory of technology innovation network,regard Chinese high-speed rail technology innovation network as the research object, through the analysis of network embeddedness on technology innovation network Chinese high rail, proposes the three elements of technological innovation network of China high rail: production network subsystem, innovation network subsystem and social culture subsystem. The collaboration between the three subsystems contributed to the success of China's high-speed rail technology innovation.
