【摘要】 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。更多还原

【Abstract】 In order to quantitatively analyze the effect of advance online publication on publishing delay and network downloads,papers of six journals published in the first issue of 2013 in CNKI were surveyed.The results show that the delay of advance online publication is 228 d,which is 76 d earlier than the print version on average.Considering the delay caused by distribution,which is around one month,papers in the advance online publication can reach readers about 100 d earlier.The average downloads per paper of the surveyed journals are 29.3 times,which can increase the network downloads by 42.5%.This new publishing model is most likely to replace the traditional print- based publishing model completely.更多还原
