论学科交叉与科学影响力的关系

On the relationship between interdisciplinarity and scientific impact

Vincent Lariviere, Yves Gingras

摘要:

本文分析了学科交叉对单个论文科学影响力的影响。利用2000年Web of Science上发表的所有论文,我们将给定论文的跨学科程度定义为其引用其他学科期刊的引用百分比。我们发现,尽管所有学科的论文的跨学科性水平和它们的引用率之间没有明显的相关性,但仍有一些学科的跨学科性水平越高,引用率越高。对于其他学科,引用随着跨学科的增长而下降。所有学科都有一个明显的特点:高度学科性和高度跨学科性的论文的科学影响力很低。这表明,可能存在一个跨学科的最佳状态,超过这个状态,研究就会过于分散,无法找到自己的位置,而在这个状态下,研究就会过于主流,无法产生很大的影响。最后,跨学科性和科学影响力之间的关系是高度决定的引用特性的学科:引用引用密集型学科的论文更有可能被这些学科引用,因此,获得更高的引用分数比引用非引用密集型学科的论文。

英文摘要:

This paper analyzes the effect of interdisciplinarity on the scientific impact of individual papers. Using all the papers published in Web of Science in 2000, we define the degree of interdisciplinarity of a given paper as the percentage of its cited references made to journals of other disciplines. We show that, although for all disciplines combined there is no clear correlation between the level of interdisciplinarity of papers and their citation rates, there are nonetheless some disciplines in which a higher level of interdisciplinarity is related to a higher citation rates. For other disciplines, citations decline as interdisciplinarity grows. One characteristic is visible in all disciplines: highly disciplinary and highly interdisciplinary papers have a low scientific impact. This suggests that there might be an optimum of interdisciplinarity beyond which the research is too dispersed to find its niche and under which it is too mainstream to have high impact. Finally, the relationship between interdisciplinarity and scientific impact is highly determined by the citation characteristics of the disciplines involved: papers citing citation intensive disciplines are more likely to be cited by those disciplines and, hence, obtain higher citation scores than papers citing non citation intensive disciplines.
