日媒:中美在科研领域引领全球 日本存在感降低

2017-08-15 14:15:22   中国网

日本经济新闻》8月15日报道称,日本文部科学省科学技术与学术政策研究所最近发布的日本国内外研究动向调查显示,在科学研究领域,呈现美国和中国引领全球、加强彼此联系的局面。日本在研究经费和研究人员数量方面居世界第3位,但在产生世界性影响的“受关注论文”数量上远远落后于中美,也落后于英国和德国等欧洲国家。日本面临着必须采取根本性对策的局面。

该研究所发布了“科学技术指标2017”和“科学研究标杆分析法2017”,汇总了截至2015年的主要国家的研究动向。

在化学和物理学等8个主要领域,比较了主要国家的被其他研究者大量引用、被认为质量高的前10%的论文(Top10%论文)数量(2013-2015年平均)。

结果显示,研究大国美国在物理学(份额占43%)、临床医学(49.3%)等4个领域论文数居首,中国也在化学(33%)和工学(29.2%)等4个领域跃居首位。相比之下,日本只有排名第5位的化学(5.6%)比较突出。

此外,调查还得出了证明中美在科研领域接近的分析结果。分析美国2013~2015年与他国一起发表的论文的共同研究伙伴国后发现,在8个主要领域中,中国在6个领域居首。此外,物理学领域美国的第一大研究伙伴国是德国,临床医学领域则是英国。

日本排名最高的是居第5位的材料科学领域。在2003~2005年,还存在一些日美合作关系,如日本在化学和材料科学领域居第3位等。但在中国崛起的背景下,对美国来说,日本的存在感正在下降。

有分析认为,全球瞩目的高质量论文更易通过国际合作产生。日本要打破现状,必须加强与美国等的海外的合作,充实向大学引入优秀海外人才的措施。
