The Quest for Originality: A New Typology of Knowledge Search and Breakthrough Inventions
研究了企业搜索原创性知识对突破性发明的影响，发现本地搜索比跨界搜索更能产生高影响力突破，基于美国纳米技术专利数据验证。
We re-examine firm exploration leading to breakthrough inventions by focusing on a new dimension of knowledge search: the search of originality. We conceptualize firm search types with two distinct dimensions—search target and search boundary—and propose contrasting effects of the search boundary in which firms search prior original knowledge on the propensities for firms to create path-breaking novelties and high-impact breakthroughs. In particular, we demonstrate that searching original knowledge and incorporating it into research and development makes local search outperform boundary-spanning search in generating high-impact breakthroughs. We argue that this advantage of local search arises from the originality that firms search and revitalize. We find robust support from the analysis of U.S. firm nanotechnology patents between 1980 and 2006. Our findings highlight the importance of searching original knowledge and the benefit of local search in creating breakthrough inventions, thereby suggesting a refinement of the conventional framework of knowledge search.
