The Cheung Kong Scholars Program has become a nationally important, high-level talent plan. In this study, we determined whether the research output and coauthorship pattern of Cheung Kong Scholars changed after their receipt of the award. We selected the 83 recipients of the 2005 Cheung Kong Scholars Award and identified a total of 11,522 Science/Social Sciences Citation Index papers published between 1996 and 2015 by these awardees. The analysis was divided into two 10-year periods—the preaward (1996–2005) and postaward (2006–15) periods—to investigate changes in the scholars’ research performance. The results revealed that the number of papers authored by each Cheung Kong Scholar increased significantly, and there were also significant increases between the two periods in terms of average citation count and journal impact factor, suggesting that the quality of the scholars’ papers improved in tandem with the quantity. Second, a quadrant chart revealed that individuals exhibited different trends in productivity and impact, but their impacts’ distribution in the postaward period was much more concentrated than that in the preaward period. Third, the scholars’ coauthorship patterns changed significantly after receiving the award—not only their number of coauthors per paper significantly increased but also their authorship role changed significantly. In both number and proportion, they became less likely to act as the first author, but more likely to be listed as the last author. Furthermore, they published more papers as corresponding author, and more papers as the first, corresponding, or last author, though their proportion did not change significantly.

跟踪获得长江学者奖学金前后的研究绩效：2005年获奖者案例研究

长江学者计划已经成为一项全国性的，高水平的人才计划。在这项研究中，我们确定了长江学者获得奖项后，其研究成果和共同作者模式是否发生了变化。我们选择了2005年长江学者奖学金的83位获奖者，并确定了这些获奖者在1996年至2015年之间发表的总共11,522篇科学/社会科学引文索引论文。该分析被分为两个10年期-前期（1996-2005年）和后期（2006-15年），以研究学者的研究绩效变化。结果显示，每位长江学者的论文数量均显着增加，并且在两个时期之间，平均引文数和期刊影响因子均显着增加，这表明学者论文的质量与数量同时提高。其次，一个象限图显示，个人在生产率和影响方面表现出不同的趋势，但是在授予后的时期中，其影响的分布要比处于授予前的时期更为集中。第三，获得奖项后，学者的共同作者模式发生了巨大变化-不仅他们每篇论文的共同作者数量显着增加，而且作者角色也发生了显着变化。无论从数量上还是从比例上看，他们都不太可能成为第一作者，但更有可能被列为最后作者。此外，尽管他们的比例没有明显变化，但他们以通讯作者的身份发表了更多论文，以第一作者，通讯作者或最后作者发表了更多论文。
