This study attempted to explain the promotion system and changes in China's publishing policy during the 13th 5-year rule period (2016-2020) and the 14th 5-year rule period (2021-2025) through literature analysis of Chinese publishing policy documents, academic research, and reporting. First of all, China's publishing-related ministries continue to support the publishing industry and public libraries during the 12th five-year period, expanding reading infrastructure in rural areas, and support overseas publications. In addition, the reading rate of Chinese people is also increasing along with the increase in the publication of paper and e-books by domestic Chinese publishers. In addition, since the Central Propaganda Department of the Communist Party of China became the responsible department of China's publishing policy from March 2018, China's publishing policy promotion system has strengthened its connection with the Communist Party and Xi Jinping's ideas and policy promotion and education. However, despite the ongoing difficulties of offline bookstores in China due to the discount competition of Chinese e-commerce companies, Chinese publishing ministries do not implement a book sales price system and only local governments in some administrative districts provide subsidies for offline bookstores. In addition, copyright infringement of overseas video content by some Chinese companies and the prohibition of publications criticizing China's political and social problems continue.
