We analyzed 2898 scientific papers published between 1995 and 2017 in which two or more authors shared the first author position. For papers in which the first and second authors made equal contributions, mixed-gender combinations were most frequent, followed by male-male and then female-female author combinations. For mixed-gender combinations, more male authors were in the first position, although the disparity decreased over time. For papers in which three or more authors made equal contributions, there were more male authors than female authors in the first position and more all-male than all-female author combinations. The gender inequalities observed among authors who made equal contributions are not consistent with random or alphabetical ordering of authors. These results raise concerns about female authors not receiving proper credit for publications and suggest a need for journals to request clarity on the method used to decide author order among those who contributed equally.
我们分析了 1995 年至 2017 年间发表的 2898 篇有两位或以上作者共同担任第一作者的科学论文。对于第一和第二作者贡献相当的论文，混合性别组合最为常见，其次是男性-男性组合，然后是女性-女性组合。在混合性别组合中，更多的男性作者处于第一作者的位置，尽管这种差距随着时间的推移而缩小。对于有三位或以上作者贡献相当的论文，处于第一作者位置的男性作者多于女性作者，而且全男性组合多于全女性组合。对于那些贡献相当的作者中存在的性别不平等现象，与作者的随机或按字母顺序排列并不一致。这些结果表明，女性作者在发表论文时没有得到应有的认可，并表明期刊有必要要求明确说明在那些贡献相当的作者中决定作者顺序的方法。
