摘要：Working paper(WP)是一类特殊的参考文献,它通常不是正式出版的论文,但常常又是最新学术思想和方法的载体,它对学术研究的推进作用是一个值得探讨的问题。本文以现代金融经济领域为研究对象,采用文献计量的方法对这个问题进行了实证研究。采用的样本为JFE杂志1998年1月至2007年10月刊登的559篇论文。设计了6个指标对WP的学术促进作用进行了统计分析。建立了三个经济计量模型分析了互联网等电子手段带来的文献传播速度加快是否促进了WP文献的学术影响。关键结论有:在现代金融经济研究领域,WP在全部参考文献的占比大约为1/10,时间影响长度大约为3.5年,互联网等手段促进了WP的使用,但没有带来增长速度的剧烈提高。
