目前正在讨论国际合作对以引文为基础的指标衡量的影响的影响。合作通常比“没有合作”的工作涉及更多的作者，很明显，自引现象会更强（有更多的作者引用自己）。因此，它可以被看作是一个重要的放大器测量的影响。虽然这种影响肯定是可能的，最近已经证明，它不应该被视为唯一的，甚至是主要的解释之间的比较“没有合作”和国际合作的影响更大。利用荷兰天文学研究的广泛文献计量学研究的数据，我们证明了在国际合作中较高的自引率并没有发挥任何重要的作用，作为“影响力指标”。中心点是，适当的影响测量必须包括自我引用的校正。
There is an ongoing discussion on the influence of international collaboration on impact as measured by citation-based indicators. Collaboration generally involves more authors than 'no collaboration' work and it is obvious that the phenomenon of self-citation will be stronger (there are more authors to cite themselves). Thus it can be seen as an important amplifier' of measured impact. Although this effect is certainly possible and already demonstrated recently, it should not be considered as the only or even major explanation of higher impact in the comparison between 'no collaboration' and international collaboration. Using data of an extensive bibliometric study of astronomical research in the Netherlands, we prove that higher rates of self-citation in international collaboration do not play any significant role as 'impact amplifier'. The central point is that proper impact measurement must involve corrections for self-citations.
