Abstract: 【Purpose/significance】People's demand for knowledge payment is increasing, but information redundancy and service
quality can’t be guaranteed, which will reduce their willingness to pay. This paper aims to explore the main influencing factors of us?
ers' willingness to pay for knowledge in social network platforms through qualitative comparative analysis, and study the combined fac?
tors of users' willingness to pay for high knowledge.【Method/process】By using Python to obtain data from the differentiating users in
the paid consultation section of Zhihu platform, three fields of workplace, health and law were selected for analysis.【Result/conclu?
sion】The research shows that the high willingness of platform users to pay is the interaction of multiple combined factors. The influ?
encing factors of users' willingness to pay are different in different fields, and some factors can be substituted for each other. The
knowledge payment platform should adopt different management strategies for users in different fields.【Innovation/limitation】This pa? per studies the linkage effect of users' willingness to pay for knowledge in social network platforms from the perspective of configura? tion, but the sample size is limited, and the analysis of influencing factors does not cover all the potential factors, which should be sup? plemented and improved in the future.
