Following 2016，the first year of knowledge payment，2017 has witnessed the continuously rapid development of China’s online knowledge payment market：users scale is expanding at a more than double rate；users are mainly the generation after 80s and 90s with middle income in first and second tiered cities；the market supply and demand are significantly featured with platformization，practicalization，centralization，audio，and low price. Although China’s knowledge payment market will maintain momentum in the following days，the growth of user scale can slow down and the problems of users retention can be serious due to many practical challenges confronted by knowledge payment platforms：homogeneity of content，difficulty of continuous production of high-quality content，lack of services and interactive functions，copyright protection and upgrading of intellectual technology and other problems. Thus，it is difficult to consistently and accurately launch high-quality content and satisfy the appeal of users’ knowledge payment experience. Taken together，it is necessary to solve the above problems for continuous and sound development of China’s knowledge payment market in the future.
