Abstract: Knowledge sharing has subverted the traditional education model, narrowed the information gap between knowledge producers and consumers, greatly reduced the cost of knowledge acquisition, at the same time, compressed the link of knowledge realization, and highlighted the value of original content. With the upgrading of consumption, knowledge sharing and knowledge payment stand on the new outlet of the Internet and develop rapidly. However, fragmented reading, low entry threshold and pan-entertainment knowledge content easily lead to the“post-truth era”of society, and online intellectual property protection is also facing a test. Government departments should further strengthen supervision, implement the main responsibility of the platform, protect intellectual property rights, ensure product quality, protect consumers’rights and interests to guide the orderly, healthy and standardized development of knowledge sharing market.

Key words: knowledge sharing, knowledge payment, middle class anxiety, fragmentation reading, post-truth era
