Addressing many of the world’s contemporary challenges requires a multifaceted and integrated approach and, in this respect, interdisciplinary research (IDR) is increasingly recognized as central to both academic interests and national science policies. In spite of the growing attention given to IDR, the impact of IDR remains under-investigated. In this study, we analyzed the influence of interdisciplinarity on citation impact (particularly, WoS citation) and broader impact (particularly, PloS usage) at the article level. We measured IDR in terms of three different elements of diversity—variety, balance, and disparity—as well as the integrated diversity overall. The results of negative binomial regression analysis with field fixed effects and robust standard errors show the positive effects of interdisciplinarity on both academic and broader impact. From an analysis of trends over time, the results show that higher interdisciplinary publications tend to attract more citations and have higher PLoS usage. Compared to citations, which need a more extended period to accumulate, the advantage of measuring impact with PLoS usage is its immediacy. Also, there are signs that PLoS usage and citations can mutually reinforce each other.

关于跨学科性和影响之间的关系：对学术和更广泛影响的不同影响

应对当今世界的许多挑战需要多方面和综合的方法，在这方面，跨学科研究 (IDR) 越来越被认为是学术兴趣和国家科学政策的核心。尽管 IDR 受到越来越多的关注，但 IDR 的影响仍未得到充分研究。在这项研究中，我们分析了跨学科性对文章级别的引用影响（特别是 WoS 引用）和更广泛的影响（特别是 PloS 的使用）的影响。我们根据多样性的三个不同要素——多样性、平衡性和差异性——以及整体的综合多样性来衡量 IDR。具有场固定效应和稳健标准误差的负二项式回归分析的结果表明，跨学科性对学术和更广泛的影响都有积极影响。从随时间推移的趋势分析来看，结果表明，较高的跨学科出版物往往会吸引更多的引用并具有更高的 PLoS 使用率。与需要更长时间积累的引文相比，使用 PLoS 衡量影响的优势在于其即时性。此外，有迹象表明 PLoS 的使用和引用可以相互促进。使用 PLoS 衡量影响的优势在于其即时性。此外，有迹象表明 PLoS 的使用和引用可以相互促进。使用 PLoS 衡量影响的优势在于其即时性。此外，有迹象表明 PLoS 的使用和引用可以相互促进。
