Abstract Incumbent firms’ collaborative R&D can reduce the R&D’ s risk and duration, also, can help incumbent firms form intergenerational knowledge bridges to avoid technological rigidity. However, for incumbent firms in different industries with different difficulties in development of new technologies and different lengths of technology intergenerational cycle, the pros and cons of intergenerational knowledge bridges on firms’ radical technological innovation may be different. Based on a panel data of 65 incumbent firms in the automobile industry from 2009 to 2019, the negative binomial regression analysis shows that collaborative R&D can directly improve the incumbent firms’ radical technological innovation performance, and both explicit and implicit intergenerational knowledge bridges can play a positive mediating role in the process. In addition, old technological innovation performance has a positive effect on the relationship between collaborative R&D and radical technological innovation performance, and a negative effect on the relationship between explicit intergenerational knowledge bridge and radical technological innovation performance, but both of them are not significant. The old technological innovation performance also has a significant negative effect on the relationship between the implicit intergenerational knowledge bridge and the radical technological innovation performance.
