The dynamics of technological partners: a social network perspective.

The selection and establishment of research partners is increasingly important in innovation and strategic research. Using a panel dataset of patents by 2846 researchers from a large US biotechnology company between 1976 and 2013, we examined the relationships between spanning structural holes and partner dynamics, which are captured by the entry of new partners and the persistence of existing partners. Then, we tested the possible moderating effect of dynamic exploratory ability. Based on the results of negative binomial regression models with fixed effects in the longitudinal design, we found that spanning structural holes was negatively associated with the entry of new partners and positively associated with the persistence of existing partners. Furthermore, exploratory ability positively moderated these relationships. Aside from having managerial implications for innovators, the findings of our interdisciplinary study are relevant for research on partner dynamics, strategy research, and exploration processes.
