Based on a longitudinal case study of a Chinese locomotive manufacturing firm (CNR Dalian) ，we are trying to explore the dominant logic of Chinese CoPs’ Innovation development in the perspective of managerial cognition. The findings show that there is a consistent dominant logic of "technical attributed" in complex product systems companies, including external drives, task definition, tasks to achieve and the protection to tasks. The cognitive logic of "Technology attribution" has played a positive role in obtaining the required key technology and product development for Chinese Complex Products and Systems Manufacturers. And it is an important reason for companies to obtain long-term performance and sustained competitive advantage, when the dominant logic is cognitive focused and cognitive flexible. The Study has also shown that, Chinese Complex Products and Systems Manufacturers should give full attention of the organizational inertia that the existing cognitive model brings, especially in seeking breakthrough for Independent Technology Innovation.
