基于新闻事业史和科学传播角度的原始期刊文献调研和考证方法，对《新青年》媒介形态作全面研究，为五四时期科学传播史研究提供典型案例。研究结果表明：《新青年》首先改用白话文和采用新式标点符号；首次实行轮值主编制度；通过赠送、交换、代派销售、登载广告等多种方式经营管理，成功地使发行量达到15000份以上；曾出版“新青年丛书”、专号或专号出单行本、合订本重印等形式，实现再传播增值或扩大传播范围。结论认为：《新青年》一扫晚清以来中文期刊传播科学多由传教士把持或国人自办期刊影响很小的局面，创造了中国近代期刊作用于社会和与时代俱进的一个奇迹。它还以其期刊类型、办刊理念、编辑模式和传播策略，影响一批新型的国人自办期刊，推进了文化的转型，引领了国人自办期刊的新方向，也使期刊载体的内涵、外延及其社会功用得到空前的提升。
