论文摘要
Covid-19-19对创新有影响吗？过去的经济中断，轶事证据和以前的文献表明，行业之间存在实质性差异。我们利用USPTO专利应用数据来调查和量化干扰。我们评估技术领域（在CPC亚类级别）的差异，以及直接和间接相关性对大流行管理的影响。直接COVID-19相关性是从专利应用程序完整文本的关键字搜索中确定的；间接COVID-19相关性来自过去的CPC亚类到子类引文模式。我们发现，直接的Covid-19相关性与大流行第一年的专利申请数量的增长相同（以相同的数量级（以百分比为单位））与参考COVID-19的专利百分比有关。我们发现对间接COVID-19的相关性没有影响，这表明专注于应用研究，而牺牲了更多的基础研究。技术领域（CPC发电局）具有额外的重大影响，例如，电源A（人类必需品）和C（化学，冶金）具有很强的性能。
Did the Covid-19 pandemic have an impact on innovation? Past economic disruptions, anecdotal evidence, and the previous literature suggest a decline with substantial differences between industries. We leverage USPTO patent application data to investigate and quantify the disturbance. We assess differences by field of technology (at the CPC subclass level) as well as the impact of direct and indirect relevance for the management of the pandemic. Direct Covid-19 relevance is identified from a keyword search of the patent application fulltexts; indirect Covid-19 relevance is derived from past CPC subclass to subclass citation patterns. We find that direct Covid-19 relevance is associated with a strong boost to the growth of the number of patent applications in the first year of the pandemic at the same order of magnitude (in percentage points) as the percentage of patents referencing Covid-19. We find no effect for indirect Covid-19 relevance, indicating a focus on applied research at the expense of more basic research. Fields of technology (CPC mainsections) have an additional significant impact, with, e.g., mainsections A (human necessities) and C (chemistry, metallurgy) having a strong performance.
