This paper presents a statistical analysis of the relationship between three science indicators applied in earlier bibliometric studies, namely research leadership based on corresponding authorship, international collaboration using international co-authorship data, and field-normalized citation impact. Indicators at the level of countries are extracted from the SIR database created by SCImago Research Group from publication records indexed for Elsevier's Scopus. The relationship between authorship and citation-based indicators is found to be complex, as it reflects a country's phase of scientific development and the coverage policy of the database. Moreover, one should distinguish a genuine leadership effect from a purely statistical effect due to fractional counting. Further analyses at the level of institutions and qualitative validation studies are recommended.

通讯作者、国际合着和国家研究系统引文影响之间的统计关系

本文对早期文献计量研究中应用的三个科学指标之间的关系进行了统计分析，即基于相应作者的研究领导力、使用国际合着数据的国际合作以及领域标准化的引文影响。国家层面的指标是从 SCImago 研究小组创建的 SIR 数据库中提取的，这些数据库是从为 Elsevier 的 Scopus 索引的出版物记录中提取的。作者和基于引文的指标之间的关系被发现是复杂的，因为它反映了一个国家的科学发展阶段和数据库的覆盖政策。此外，人们应该将真正的领导效应与由于分数计数而产生的纯粹统计效应区分开来。
