科技论文视域下国际物理学科学中心与转移路径识别研究

Study on the identification of international physics science centers and transfer paths in the perspective of scientific and technical papers

综合科技多样化指数、科技专业化指数、社会网络分析法,构建国际物理学科学中心与转移路径识别模型,基于2003-2022年全球物理学领域代表性期刊论文数据,实现国际物理学科学中心及其转移路径识别。研究发现:(1)美国作为国际物理学科学中心具有绝对优势,但多中心格局或将成为大势所趋;(2)德国、英国、法国、瑞士、日本、中国等国家同美国的距离逐渐缩小,构成国际物理学研究的“一超多强”局面;(3)国际物理学科学中心呈现出从由美国向欧洲转移,再由欧洲向亚洲转移的态势。

Based on the data of the papers published in the Web of Science database from 2003 to 2022 in the field of physics,the identification of scientific centers and the identification of transfer paths in physics are realized by using the Technological Diversity Index,Technical Specialization Index and the method of social network analysis.The study found:(1)The United States has an absolute advantage as an international physical science center,but a multi-center pattern may become the general trend.(2)The distance between Germany,the United Kingdom,France,Switzerland,Japan,China and other countries and the United States is gradually narrowing,forming a“super strong and multi”situation in international physics research.(3)The international physical science center shows a trend of shifting from the United States to Europe and then to Asia.
