Abstract: 【Purpose/significance】In order to reveal the internalization process, action mechanism and internal motivation of user knowledge in the context of social question answering, and to improve the knowledge utilization and reuse rate of the social Q&A com⁃munity【. Method/process】This study firstly constructed a user knowledge internalization process model in the context of social question answering based on cognitive theories such as assimilation adaptation theory and information processing learning, and analyzed its mechanism of action. Then, From the perspective of configuration, using fuzzy set qualitative comparative analysis (fsQCA) method to analyze the motivation mechanism and influencing factors of user knowledge internalization in the context of social question answering.
【Result/conclusion】The study found that the user's knowledge internalization in the context of social question and answer is based on the user's existing cognitive structure as a constraint mechanism. After knowledge assimilation and adaptation, it is monitored by meta-cognition, and then regulated by knowledge feedback. At the same time, it is affected by two factors: the ability of community communication and the ability of users to absorb themselves. The conditional configuration paths that promote the occurrence of user knowledge internalization in the context of social question answering include user-promoting and platform-facilitating types; the con⁃ditional configuration paths that inhibit the occurrence of user knowledge internalization in the context of social questioning are userinhibiting and platform-promoting. There are two types of platform inhibition.【Innovation/limitation】The research needs to analyze
the causes of knowledge internalization and differentiation of users in different types of socialized question and answer communities.
