中科院:停止为《自然-通讯》《科学进展》等30种开放获取期刊支付发表费
Xin Lang Cai Jing· 2026-02-25 08:10
加拿大卡尔加里大学(University of Calgary)研究中国学术出版政策的博士生唐耿岩(Gengyan Tang) 表示,中国的科研资助者越来越强调支出的效率和问责,"任何对APC报销的限制,都可以被理解为这 一更广泛努力的一部分,而不是对开放获取期刊的彻底否定。" 报道称,自2019年以来,中国政府一直在推进一项计划,发展400种世界级的科学期刊,作为西方科学 期刊经济实惠的代替品。根据出版咨询公司Osmanthus Consulting和Clarke & Esposito2023年发布的报 告,截至2023年,中国约有178本英文开放获取期刊,其中近一半不收取APC。 目前,APC收入主要流向国际出版商,中国以及其他地区的许多人认为,让全球一些最大的出版商获取 过高利润,是一种不可持续的做法。 据《科学》网站当地时间2月24日消息,3月1日起,全球最大的科研机构中国科学院将停止为在《自然- 通讯》《细胞报告》《科学进展》等30种高价开放获取(Open Access)期刊上发表论文支付费用。 观察人士称,此举可能旨在控制成本,并可能推动中国本土期刊发展。 中科院北京总部 《科学》网站 据报道,一 ...
