General purpose technologies (GPTs) exhibit strong externalities and innovational complementarities. Their diffusion within supply chains and impact on the technology ecosystem are of significant interest to both industry and academia. Based on the resource dependence theory and absorptive capacity theory, the nonlinear effects of leader firms' GPT innovation on the technological complementarity between leader firm and its supply chain partners was examined. It also explores the boundary conditions of these effects. Analyzing panel data from 1,405 firm-year observations of 145 biopharmaceutical firms from 2010 to 2019, the findings reveal that an inverted U-shaped effect of GPT innovation performance on the technological complementarity between leader firm and its supply chain partners.Within the supply chain, partners' capability in GPT innovation positively moderates this inverted U-shaped relationship.
