核心期刊评选影响了读者的关注度吗*--来自农业期刊的证据

摘要

The selection of core journals will have impact on the future development of academic journals deeply, which is called the ulte-rior effects. In order to analyze the changing of readers' journal attention, this paper chooses six agricultural journals for study objects and uses Baidu index as the proxy variable of readers' attention. Results indicate that the selection of core journals cannot affect the attention of top journals, but it can influence the attention of newly selected core journals, which rises sharply, and it can impact the attention of e-liminated core journals with an obvious descending curve thereafter.%核心期刊评选将深刻地影响学术期刊的发展，我们称之为后效应。本文选取6本农业期刊作为研究对象，利用百度指数作为读者关注度的代理变量，分析了核心期刊评选之后读者关注度的变化情况，结果表明：核心期刊评选无法影响在期刊排名中长期名列前茅的“大刊老刊”的关注度；核心期刊评选会提升新入选的期刊的读者关注度；被剔除出核心期刊目录的非核心期刊的读者关注度会下降。
