关于图书馆学实证研究中数据内生性问题的思考

摘要

Endogenous problems are common in quantitative research in social science.Compared with other research in social science, little quantitative research in library sciences in China focuses on endogenous problems, which may exaggerate some empirical research conclusion and even make some research conclusion incorrect.To solve this problem,this article introduces three econometrics methods to deal with endogenous problems,including instrumental variable,difference in differences model and regression discontinuity,which are considered to be potential in library science study and will greatly broaden the research scope.%社会科学定量研究中往往存在内生性问题,相对于其他社会学科,国内图书馆学以往的定量研究缺乏对内生性问题的关注,这不仅会导致相关实证研究结论可能存在夸大问题,甚至会导致某些研究结论不成立.针对这一现象,文章介绍了工具变量、双重差分法和断点回归法三种计量经济学处理内生性问题的方法在图书馆学实证研究中的应用,认为这三种方法不但在图书馆学有广阔的应用空间,还可以极大地拓展图书馆学的研究范围.
