为了定量分析优先数字出版对论文发表时滞和网络下载量的影响,在中国知网优先数字出版平台中,统计了6种期刊2013年第1期论文。结果表明:优先版发表时滞为228 d,比纸质版平均提前了76 d,加上1个月的印发时滞,能提前100d左右与读者见面。被统计期刊优先版篇均下载量为29.3次,能提高42.5%的网络下载量。这一新的出版模式,极有可能将彻底取代传统科技期刊纸质出版。 In order to quantitatively analyze the influence of priority digital publication on the publication delay and the network download volume, six kinds of periodicals in 2013 issue No. 1 paper are counted in the priority digital publication platform of CNKI. The result shows that the delay of publication in the first edition is 228 days, which is 76 days ahead of the paper version in general. With one month ’s printing time lag, it can meet the readers about 100 days in advance. The first edition of the statistical periodicals was downloaded 29.3 times, 42.5% increase in network downloads. This new publishing model, most likely to completely replace the traditional science and technology journals published in paper.
