Purpose

This study explores whether interdisciplinary components' citation intensity (ICCI) affects papers' scientific impact. In this study, the term “interdisciplinary components” refers to the disciplines that are different from the discipline to which the target research belongs. The citation intensity is the degree of density or sparseness of the paper citation network for a discipline. Previous studies have shown that the scientific impact of interdisciplinary research is influenced by interdisciplinarity and its properties, namely, variety, balance and disparity. However, the effect of ICCI on scientific impact has not been comprehensively explored.

Design/methodology/approach

This study is based on the entire publication database of the Web of Science for the year 2000, where the authors provide an indicator to measure the ICCI of each publication. A tobit regression model is used to examine the effect of ICCI on scientific impact, controlling for a range of variables associated with the characteristics of the publications studied.

Findings

The results show that ICCI has a positive effect on scientific impact. The authors’ results further point out that ICCI displays a curvilinear inverted U-shape relationship with scientific impact. It means that including more citation-intensive interdisciplinary components can increase the scientific impact of interdisciplinary research. However, excessive use of citation-intensive interdisciplinary components may reduce the scientific impact of interdisciplinary research.

Originality/value

This study shows that, in addition to interdisciplinarity, the scientific impact of interdisciplinary research is also affected by the citation characteristics of interdisciplinary components, namely ICCI.

交叉学科组成部分的引用强度对科学影响力的影响

目的

本研究探讨了跨学科组成部分的引用强度 (ICCI) 是否会影响论文的科学影响力。在本研究中，术语“跨学科组成部分”是指与目标研究所属学科不同的学科。引文强度是指某一学科论文引文网络的密集程度或稀疏程度。以往的研究表明，跨学科研究的科学影响受跨学科性及其性质的影响，即多样性、平衡性和差异性。然而，尚未全面探讨 ICCI 对科学影响的影响。

设计/方法/方法

本研究基于 2000 年 Web of Science 的整个出版物数据库，作者提供了一个指标来衡量每个出版物的 ICCI。Tobit 回归模型用于检查 ICCI 对科学影响的影响，控制与所研究出版物特征相关的一系列变量。

发现

结果表明，ICCI对科学影响有积极影响。作者的结果进一步指出，ICCI 显示出具有科学影响的曲线倒 U 形关系。这意味着包含更多引用密集型跨学科组件可以增加跨学科研究的科学影响。然而，过度使用引文密集的跨学科组件可能会降低跨学科研究的科学影响。

原创性/价值

本研究表明，除了跨学科性外，跨学科研究的科学影响还受到跨学科组成部分的引文特征的影响，即 ICCI。
