Abstract：
Previous studies on COVID-19 scholarly articles have primarily focused on bibliometric characteristics, neglecting the identification of institutional actors that cite recent scientific contributions related to COVID-19 in the policy domain, and their locations.
The purpose of this study was to assess the online citation network and knowledge structure of COVID-19 research across policy domains over 2 years from January 2020 to January 2022, with a particular emphasis on geographical frequency. Two research questions were addressed. The first question was related to who has been the most active in policy engagement with science and research information sharing during the COVID-19 pandemic, particularly in terms of countries and organization types. The second question was related to whether there are significant differences in the types of coronavirus research shared among countries and continents.
The Altmetric database was used to collect policy report citations of scientific articles for 3 topic terms (COVID-19, COVID-19 vaccine, and COVID-19 variants). Altmetric provides the URLs of policy agencies that have cited COVID-19 research. The scientific articles used for Altmetric citations are extracted from journals indexed by PubMed. The numbers of COVID-19, COVID-19 vaccine, and COVID-19 variant research outputs between January 1, 2020, and January 31, 2022, were 216,787, 16,748, and 2777, respectively. The study examined the frequency of citations based on policy institutional domains, such as intergovernmental organizations, national and domestic governmental organizations, and nongovernmental organizations (think tanks and academic institutions).
The World Health Organization (WHO) stood out as the most notable institution citing COVID-19-related research outputs. The WHO actively sought and disseminated information regarding the COVID-19 pandemic. The COVID-19 vaccine citation network exhibited the most extensive connections in terms of degree centrality, 2-local eigenvector centrality, and eigenvector centrality among the 3 key terms. The Netherlands, the United States, the United Kingdom, and Australia were the countries that sought and shared the most information on COVID-19 vaccines, likely due to their high numbers of COVID-19 cases. Developing nations, although gaining quicker access to COVID-19 vaccine information, appeared to be relatively isolated from the enriched COVID-19 pandemic content in the global network.
The global scientific network ecology during the COVID-19 pandemic revealed distinct types of links primarily centered around the WHO. Western countries demonstrated effective networking practices in constructing these networks. The prominent position of the key term \"COVID-19 vaccine\" demonstrates that nation-states align with global authority regardless of their national contexts. In summary, the citation networking practices of policy agencies have the potential to uncover the global knowledge distribution structure as a proxy for the networking strategy employed during a pandemic.

摘要：
背景：以前关于COVID-19学术文章的研究主要集中在文献计量特征上，忽略了在政策领域引用与COVID-19相关的最新科学贡献的机构行为者的识别，和他们的位置。
目的：本研究的目的是评估2020年1月至2022年1月2年间跨政策领域的COVID-19研究的在线引文网络和知识结构，特别强调地理频率。解决了两个研究问题。第一个问题是关于在COVID-19大流行期间谁在科学和研究信息共享的政策参与方面最活跃，特别是在国家和组织类型方面。第二个问题与各国和各大洲之间共享的冠状病毒研究类型是否存在显着差异有关。
方法：Altmetric数据库用于收集3个主题（COVID-19，COVID-19疫苗，和COVID-19变体）。Altmetric提供了引用COVID-19研究的政策机构的网址。用于Altmetric引文的科学文章是从PubMed索引的期刊中提取的。COVID-19，COVID-19疫苗的数量，2020年1月1日和2022年1月31日之间的COVID-19变体研究产出分别为216,787、16,748和2777。这项研究基于政策制度领域检查了引用的频率，如政府间组织，国家和国内政府组织，和非政府组织(智库和学术机构)。
结果：世界卫生组织（WHO）是引用COVID-19相关研究成果的最著名机构。世卫组织积极寻求和传播有关COVID-19大流行的信息。COVID-19疫苗引文网络在程度中心性方面表现出最广泛的联系，2-局部特征向量中心性，和3个关键术语中的特征向量中心性。荷兰,美国,联合王国,澳大利亚是寻求和分享COVID-19疫苗信息最多的国家，可能是由于他们大量的COVID-19病例。发展中国家,尽管可以更快地获取COVID-19疫苗信息，似乎与全球网络中丰富的COVID-19大流行内容相对隔离。
结论：COVID-19大流行期间的全球科学网络生态学揭示了主要围绕世界卫生组织的不同类型的联系。西方国家在建设这些网络方面表现出了有效的网络实践。关键术语“COVID-19疫苗”的突出地位表明，无论其国家背景如何，民族国家都与全球权威保持一致。总之,政策机构的引文联网做法有可能揭示全球知识分布结构，作为大流行期间采用的联网战略的代理。
