We identified 16,011 inventors’ locations of the 93 most innovative U.S. pharmaceuticals and biotechnology companies on the EU Industrial R&D Investment Scoreboard. We tracked their patents from 2001 to 2013 and constructed a panel dataset for analysis. Using firm-location fixed effect models, we found that the average tie strength of a location's egocentric network has a negative effect on innovation radicalness, and this negative effect is stronger when the location's egocentric network is cohesive. This suggests that weak ties have informational advantages for radical innovation, which are more pronounced when there is network cohesion to mitigate the relational disadvantages of weak ties. We also found a negative effect of structural holes on innovation radicalness when tie strength is weak but a positive effect when tie strength is strong. This indicates that strong ties are needed for mobilizing the informational advantages associated with structural holes. date: 2025-02 date_type: published publisher: Elsevier BV official_url: https://doi.org/10.1016/j.joi.2024.101636 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2354144 doi: 10.1016/j.joi.2024.101636 lyricists_name: Jong, Simcha lyricists_id: JSIMC08 actors_name: Jong, Simcha actors_id: JSIMC08 actors_role: owner full_text_status: public publication: Journal of Informetrics volume: 19 number: 1 article_number: 101636 issn: 1751-1577 citation: Zhang, Jia; Wang, Jian; Winnink, Jos; Jong, Simcha; (2025) Collaboration networks and radical innovation: Two faces of tie strength and structural holes.
