Regional recombinant novelty, related and unrelated technologies: a patent-level approach
利用1990-2010年法国专利数据，研究发现区域技术相关性促进增量创新但降低重组新颖性，而新技术、不相关或非本地专业化技术能缓解这种负面影响。
This paper investigates the impact of regional technological relatedness on the emergence of recombinant novelty (i.e., new combinations of subclasses occurring for the first time) in French regions using patent data over the period 1990–2010. We find that relatedness favours incremental innovations that reuse already applied combinations, whereas increasing levels of relatedness reduce the likelihood of novelty. However, the impact is less negative when combined technologies are new, unrelated or not locally specialized because it facilitates learning and technological recombination. We also find that universities and large incumbents are less dependent on relatedness than small and novel players to create novelty.
