简介：合作是科学研究中很重要的一部分，随着各学科知识的不断积累，个体研究者只能成为某一领域的专家。因此，现在有越来越多合作形式的科学论文出现。科学计量学领域的许多工作都是致力于分析科学家合作网络的结构特点，然而对于这种合作会如何影响青年学者未来的科研职业生涯发展的研究是很少的。在这篇文章中，我们对美国物理学会（APS）从1893年至2009年的包括325491位作者和458584篇科学论文的实际数据进行了这一方面的分析。分析结果显示，与杰出学者（通过他们文章的总引用数量衡量）合作对青年学者的职业生涯发展有显著的积极影响，并且这种影响具有很强的非线性，可以被拟合为指数小于1的幂函数的形式。进一步的分析表明，这种对于青年学者的积极影响主要表现在其科学职业生涯的前期。同时经过比较1960年至1990年数据，可以发现这种影响是随着时间逐渐增强的。

Abstract

Collaboration is one of the key features in scientific research. With more and more knowledge accumulated in each discipline, individual researcher can only be an expert in some specific areas. As such, there are more and more multi-author papers nowadays. Many works in scientometrics have been devoted to analyze the structure of collaboration networks. However, how the collaboration impacts an author’s future career is much less studied in the literature. In this paper, we provide empirical evidence with American Physical Society (APS) data showing that collaboration with outstanding scientists (measured by their total citation) will significantly improve young researchers’ career. Interestingly, this effect is strongly nonlinear and subject to a power function with an exponent less than 1. Our work is also meaningful from practical point of view as it could be applied to identifying the potential young researchers.
