Abstract: This study investigates the relationship between the technological value of collaborative research and development (R&D) outcomes and technological diversity in inter-firm R&D alliances. We differentiate technological diversity into two types—relational technological diversity (RTD) and distributional technological diversity (DTD)—and relate them to distinct mechanisms. By empirically analyzing 18,575 granted U.S. patent applications from 1993 to 2002, we find that RTD and DTD is negatively associated and positively associated, respectively, with the technological value of R&D outcomes. In addition, we consider two hypothesized moderators—team size and exploratory degree—in order to examine the moderation effects. The results show that the negative effect of RTD becomes stronger when team size is larger, and the positive effect of DTD becomes greater when an alliance attempts to invent in a less familiar technological field where the exploratory degree is higher. Moreover, we find that RTD and DTD interact in their influences on outcomes.
