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.
