中美热点论文比较分析

Comparative Analysis on Hot Papers of China and USA

[目的/意义]对中美热点论文进行比较分析,为提升我国科研创新能力提供参考。[方法/过程]借助ESI数据库和Web of Science数据库,对中美热点论文的学科分布、研究方向、论文合著的国家和地区分布、施引文献的国家和地区分布等进行对比分析。[结果/结论]美国热点论文的数量远超中国,两国热点论文的学科分布和研究方向存在较大差异。中国的热点论文主要集中在化学、工程学和物理等学科,但对内科学、神经科学和肿瘤学等学科的创新性研究较弱。热点论文合著及施引文献的国家和地区分布广泛,中国与世界许多国家和地区有着密切的科研合作,为世界科技的发展做出了巨大贡献。

[Purpose/significance]The paper is to make the comparative analysis on hot papers of China and USA,which aims to provide reference for promoting research innovation in China.[Method/process]The paper takes hot papers of China and USA from ESI database and Web of Science database as research subjects,and makes the comparative analysis on some aspects including subject distribution,research direction,and countries（regions） distribution of co-authors and citing articles.[Result/conclusion]The number of hot papers of USA is much more than that of China,and there are significant differences in subject distribution and research direction among hot papers of these two countries.Hot papers of China focus on chemistry,engineering and physics disciplines,but there are few innovative researches on internal medicine,neuroscience and oncology disciplines.The countries（regions） of co-authors and citing articles distribute widely,which reveals that China has established closely scientific cooperation with other countries（regions） of the world and has made great contributions to the development of world＇s science and technology.
