分析了1991-2000年间经济学文献中卫生经济学文章的发表趋势，发现文章数量、页数和期刊数增加，单一作者比例下降，多作者合作增加，作者集中度降低。
This paper describes and analyzes trends in health economics articles indexed in the economics literature from 1991 to 2000, demonstrating the robust state of publication in the field during the past decade. While articles, pages, and the number of journals increased, single authorship declined dramatically from almost half of articles published to only one-third, and papers with four or more authors increased three-fold. Over three-fourths of articles were analyses of healthcare markets or health production, while policy oriented articles constituted the third largest share. Author concentration ratios decreased almost by half and the Herfindhal-Hirschman index of author concentration declined from 14 in 1991 to only 4 in 1999.
