：文章介绍了国外几个典型的图书开放获取案例，总结出了适合学术图书开放获取的几个政策机制，包括已有的主要针对论文的基于开放获取经费管理的回馈+监督+激励惩罚机制、图书所特有的分层按需出版机制和图书开放出版的市场选择机制、针对图书特点将主要针对论文类的开放获取政策进行适应性改进后图书开放获取的“时滞”机制和基于图书馆联盟的订购经费转移机制等，认为这些政策机制能有效解决图书开放获取中的各种障碍，切实推进图书的开放获取。

This paper introduced some books open access cases，analyzed and summarized the policy mechanism that is suitable for the OA of academic books, including several existing open access policies which were mainly for papers such as the feedback mechanism of supervisory + encouragement and punishment, the book-specific on-demand publishing mechanism, the market selection mechanism of books' open publication and the "Delay" mechanism, and the transfer mechanism of subscription funds that is based on the library alliance. It was thought that the policy mechanisms mentioned above can effectively solve the obstacles and promote the progress of books' open access, and can provide some reference for the formulation of books open access policies.
