New Product Search Over Time: Past Ideas in Their Prime?
研究了企业搜索的知识年龄如何影响创新，发现行业内旧知识阻碍创新，而行业外旧知识促进创新，基于131家机器人企业的纵向数据。
This paper investigates how the age of the knowledge that firms search affects how innovative they are. Two seemingly contradictory propositions are examined: (1) old knowledge hurts by making innovation activities obsolete, and, (2) old knowledge helps because it is more reliable and legitimate, thereby promoting innovation. Results based on longitudinal data on 131 robotics firms reconcile the contradictory propositions: while old intra-industry knowledge hurts, old extra-industry knowledge promotes innovation.
