Under the guidance of positive performance, the proactive innovation behavior out of individual intention will bring significant and lasting innovation performance for the organization. However, the research of generating mechanism hasn’t been involved so much. On the one hand, external value pursuit is an important factor to drive positive behavior of the workplace. On the other hand, the impact of external value on the innovation is still different. Therefore, based on the theory of work value orientation, and from the perspective of external value, this research, through the empirical analysis of 477 questionnaires, chooses career orientation to explore the mechanism of proactive innovation behavior of technical personnel. The results show that: 1. Career orientation of technical personnel will burst out more proactive innovation behavior; 2. Identified motivation can well reveal their internal function relationship; 3. The moderating effect of information seeking, subjective norm and distributive justice play an important positive role in the formation of identified motivation at the individual, group and organizational level.
