Abstract:  Academic papers are an important expression of research outcomes of researchers,and the relationship between the number of authors and number of papers is expected to follow the pattern of research development.Using literature statistics,this analysis systematically and comprehensively examines all papers published in seven CSSCI population journals from the first issue to 2009.The major findings are:(1) the probability distribution of different paper size of authors among the total authors follows the Lotka Rule,and the proportion of new authors and old authors are reasonable in the seven journals;(2) new authors in the seven journals is significantly lower than the optimal value of Lotka Rule,suggesting that the research team is stable,but shows a sign of "aging" of authors due to lack of vitality.

Keywords: Authors of Journal Papers, Population Study, Lotka Rule

摘要： 论文是科研人员从事科学研究产生成果的重要表现形式,作者数量和文献数量之间的关系是遵循科学研究发展的客观规律。通过使用文献计量学的方法,对7种人口学CSSCI期刊自创刊起至2009年的全部论文进行分析,主要发现:(1)7种期刊不同论文数量的作者占作者总人数的概率分布都遵循Lotka定律,新老作者结构合理;(2)7种期刊新增量都显著低于理论最佳值,说明学术研究队伍非常稳定,但是活力不足,容易出现作者"老化"现象。
