Scientific novelty is important during the pandemic due to its critical role in generating new vaccines. Parachuting collaboration and international collaboration are two crucial channels to expand teams' search activities for a broader scope of resources required to address the global challenge. Our analysis of 58,728 coronavirus papers suggests that scientific novelty measured by the BioBERT model that is pre-trained on 29 million PubMed articles, and parachuting collaboration dramatically increased after the outbreak of COVID-19, while international collaboration witnessed a sudden decrease. During the COVID-19, papers with more parachuting collaboration and internationally collaborative papers are predicted to be more novel. The findings suggest the necessity of reaching out for distant resources, and the importance of maintaining a collaborative scientific community beyond established networks and nationalism during a pandemic.

大流行能改变科学创新吗？来自 COVID-19 的证据

科学创新在大流行期间很重要，因为它在生产新疫苗方面发挥着关键作用。跳伞合作和国际合作是扩大团队搜索活动以获取应对全球挑战所需的更广泛资源的两个重要渠道。我们对 58,728 篇冠状病毒论文的分析表明，在 COVID-19 爆发后，由 BioBERT 模型衡量的科学新颖性和跳伞合作在 2,900 万篇 PubMed 文章上进行了预训练，急剧增加，而国际合作却突然减少。在 COVID-19 期间，具有更多跳伞合作和国际合作论文的论文预计将更加新颖。研究结果表明有必要接触遥远的资源，
