Hong Kong's publishing market is the third largest Chinese publishing market except Chinese mainland and Taiwan Province Province, and there is obviously a tendency to surpass Taiwan Province Province to become the second. Due to the increasingly frequent economic and cultural exchanges between Hong Kong and the mainland of China, Hong Kong's inherent economic foundation, international status and free and open environment, the development advantages of Hong Kong's publishing industry are increasingly prominent. Among them, the Hong Kong Book Fair has become the largest book fair in Asia, attracting the attention of the global publishing industry.

However, due to the small size of Hong Kong and the population restriction, more Hong Kong publishing houses are expanding their markets around by "going out", especially the China market, and the mainland of the motherland is the top priority of their future markets.

However, the mainland has strict control over the entry of overseas books into the mainland market, so Hong Kong publishing houses can not gain the same market position as mainland publishing houses for the time being, and Hong Kong books can not enter mainland bookstores for sale and distribution in large quantities. Mainland officials only symbolically import a few books from Hong Kong and Taiwan to one or two foreign bookstores for sale, which is more symbolic than practical.

Therefore, Hong Kong Publishing House can only co-publish with mainland authors through self-funded publishing. I believe that with the deepening of the reunification, the policy bottleneck will eventually break through. Some far-sighted Hong Kong publishing houses have made active preparations, such as Huaxia Culture Publishing House, which has brought the review standards of manuscripts closer to the relevant publishing regulations in the Mainland, banned the publication of books that are reactionary, pornographic and split the motherland, and strengthened cooperation with mainland publishing houses in order to seize market opportunities after the policy is loosened.
