The objective of this study was to elicit the factors related to worldwide variation in biomedical research productivity.
Biomedical research articles published in 1990-2000 were accessed through the MEDLINE database. The number of articles (journal articles) originating from each of the countries of the world was elicited and normalized to publication per million population per year.
In a multiple regression model, where publication per million population was the dependent variable and 10 social and economic indicators were independent variables, gross national product (GNP) per capita and research and development (R&D) expenditure emerged as significant factors. In separate simple linear regression analyses, all but two independent variables were found significant.
To increase biomedical research output, GNP per capita and R&D expenditure are the most important factors to address.
本研究的目的是找出与全球生物医学研究生产力差异相关的因素。
通过MEDLINE数据库获取1990 - 2000年发表的生物医学研究文章。统计来自世界各国的文章数量（期刊文章），并将其标准化为每年每百万人口的发表量。
在一个多元回归模型中，以每百万人口发表量为因变量，10个社会和经济指标为自变量，人均国民生产总值（GNP）和研发（R&D）支出成为显著因素。在单独的简单线性回归分析中，除两个自变量外，其他所有自变量均具有显著性。
为了提高生物医学研究产出，人均GNP和研发支出是需要解决的最重要因素。
