Research innovation can be fostered under the right circumstances, which include high levels of research autonomy, opportunities for collaborative research, and an open-minded research community able to combine innovation with more conventional lines of research. In the literature, different types of collaboration and team composition are linked to innovation. However, little is known about the association between collaborative research and the consolidation of thought products, innovative or not. We address this research gap based on 2,785 abstracts and 352 'thought products' (theories, methods, research topics) extracted from five German language sociology journals included in Scopus and published between 2000 and 2019. We apply a diachronic research strategy and combine correspondence analysis for topic extraction, network analysis to account for the embeddedness of scholars, and OLS regression to investigate which of the factors present in 2000-2003 are responsible for the consolidation of thought products in 2016-2019. We find that a focus on applied topics (such as management or governance) is positively linked to the consolidation of research. Furthermore, concepts used and disseminated by well-connected scholars between 2000 and 2003 tend to become peripheral over time. Finally, we establish a negative association between concepts used by female scholars and the consolidation of these concepts.
