Inter-Firm Inventor Collaboration and Path-Breaking Innovation: Evidence From Inventor Teams Post-Merger
利用1976至2019年追踪发明人职业路径的数据，发现并购后收购方与目标方发明人合作比单方团队更能产生突破性专利，且合作比雇佣或知识溢出更能提升创新能力，机制是重组双方人力资本中的隐性知识。
Abstract Using a large and novel data set over the period of 1976 to 2019 tracking inventors’ career paths following mergers and acquisitions, we show that collaboration between acquirer and target inventors post-merger is associated with more path-breaking patents than those filed by either acquirer or target inventor-only teams. We further show that such collaboration is more important in improving acquirers’ innovation capabilities than hiring target inventors and knowledge spillovers. Finally, we show that recombining tacit knowledge embodied in the human capital of acquirer and target inventors is likely the mechanism. We conclude that inter-firm inventor collaboration is one key means for achieving synergies.
