不得了，物价房价涨就算了，期刊的版面费也涨价了。众所周知，MDPI系列的期刊广受欢迎，发文量大而且对国人非常友好，算是很多医生的首选了！可今天小爱突然发现，最新版面费是不是不太对？出于好奇，登录了MDPI的官网，发现了一个惊人的事情：MDPI旗下的期刊在2023年6月30日之后，版面费即将暴涨！

据官方消息，MDPI出版社旗下期刊的OA论文处理费（APC），价格将在2023年6月底上涨，超过90种OA期刊的APC涨幅在200-1200瑞士法郎（折合人民币1560元-9300元）。以下是MDPI最新调整：以我们熟知的Cells为例，在最新官网上公布的消息来看：Cells是一本OA杂志，论著的APC的费用为2400瑞士法郎，约合人民币1.8万元。到今年6月30日，该刊的版面费将升至2700瑞士法郎，约合人民币2万元。该期刊2021年的版面费：2000瑞士法郎。而在2019年的时候，Cells的版面费还是1800瑞士法郎，等于短短5年间，上涨了900瑞士法郎，折合人民币7000元。

在MDPI出版的OA期刊中，有5种期刊处于2022年中国通讯作者发表OA论文数量排名前10的期刊：Sustainability，Remote Sensing，International Journal of Environmental Research and Public Health，International Journal of Molecular Sciences 和 Materials。这5种期刊的APC将增长200～400瑞士法郎。

General Information on MDPI’s Article Processing Charges (APC)

MDPI publishes all its journals in full open access, meaning unlimited use and reuse of articles, in addition to giving credit to the authors. All of our articles are published under a Creative Commons (CC BY) license.

Authors pay a one-time Article Processing Charge (APC) to cover the costs of peer review administration and management, professional production of articles in PDF and other formats, and dissemination of published papers in various venues, in addition to other publishing functions. Please note that the option to process an advance payment remains but does not guarantee acceptance of manuscripts. There are no charges for rejected articles, no submission charges, and no surcharges based on the length of an article, figures or supplementary data. Some items (Editorials, Corrections, Addendums, Retractions, Comments, etc.) are published free of charge.

Here is a breakdown of how our APCs are used. In calculating these values, we have followed recommendations from the Fair Open Access Alliance, an organization that promotes sustainable and transparent scholarly open access publishing. This also makes MDPI fully compliant with the requirements of Plan S, a key funder initiative to promote Open Access.

就不知此次MDPI集体涨价会对期刊或者编辑有何影响呢？毕竟先前也有过神经科学成像领域的顶级期刊 NeuroImage主编宣称，NeuroImage及其姊妹刊 NeuroImage:Reports 的所有编辑因不满出版商Elsevier（爱思唯尔）收取高额版面费，全体辞职，并将创办一份新的非营利性的开放获取期刊Imaging Neuroscience，取代 NeuroImage 在神经成像领域的领头地位。其APC费用为3450美元，约合人民币2.3万元左右。
