中美在石墨烯领域的研究轨迹及政策建议

Patterns,dynamics and policy suggestions of graphene research in China and the U.S.

本研究以大规模石墨烯科技文献数据库为样本来分析中美两国在该交叉前沿学科领域的总体概况、发展轨迹和驱动力量。通过运用多种数据可视化工具,研究发现,中国在石墨烯领域是一个早期进入者而不是一个后发追赶者。中国石墨烯的研究在早期与美国有短暂的时间延迟,中期迅速赶上,目前在数量上已超越美国。中美双方在国际石墨烯科研成果中占据首要地位,互为彼此的最主要合著者。中美两国在石墨烯研究发展轨迹上既有趋同性也有相异之处。从石墨烯项目资助的金额和石墨烯研究成果的发表数量上看,国家层面的大力扶持对两国的石墨烯研究起到不可忽视的作用。最后,文章提出了科研管理的相关政策建议。

Utilizing a uniquely constructed global publication database of graphene, this research aims to profile the patterns and dynamics of China＇ s graphene research and compare it against that of the US. Multiple instruments of data visualization are applied in this research. Our analysis highlights China＇ s relatively early entry and dramatic growth in the emerging field of graphene. We found that China and the U.S. are dominant players in this domain. They are most favorite collaborators of each other. Public funding plays important roles in stimulating graphene research. Evidence supports research convergence between China and the U. S. , but we also note that each country demonstrated different development path. Policy implications are discussed in the end.
