Facing the fierce market competition, enterprises need to handle the relationship between the existing technologies and technological innovation well. This study takes the Pearl River Delta manufacturing enterprises as the research object. From the perspective of combining internal and external factors, we explored how enterprises weigh the exploitative technological innovation and exploratory technological innovation. Results of this study show that: Resource rigidity has positive relationship with exploitative technological innovation and negative relationship with exploratory technological innovation; routine rigidity is positively related to exploitative technological innovation and negatively related to exploratory technological innovation. The network position plays a negative moderating role on the relationship between resource rigidity and exploitative technological innovation, resource rigidity and exploratory technological innovation, routine rigidity and exploratory technological innovation.
