  • Research on the Configuration of Influencing Factors Affecting User Knowledge Willingness Payment in Online Q & A Community from the Perspective of Reason and Status Quo Bias

    Subjects: Library Science,Information Science >> Information Science submitted time 2023-04-01 Cooperative journals: 《图书情报工作》

    Abstract: [Purpose/significance] The knowledge payment behavior of users is a complex decision-making process that is affected by the synergy of multiple factors. It is of great significance to explore the combined effect of factors affecting the willingness of users to pay for knowledge in the context of free knowledge acquisition. This study can help to understand the knowledge payment behavior of users and promote the sustainable development of the paid Q & A community. [Method/process] This paper constructed latent variables that affect users' willingness to pay for knowledge based on the current state deviation theory and rational choice theory. The fsQCA method was used to analyze the asymmetric multiple concurrent causality between the variables, and to explore the configuration of the willingness to pay for knowledge. [Result/conclusion] The study has found that, in the presence of free information acquisition channels, the willingness of users in the paid question-and-answer community to pay for knowledge is the result of multi-factor interactions at the level of rationality and bias. Perceived revenue is the most critical factor for a high degree of willingness to pay for knowledge. The idea of personal free is an important influencing factor of low-level knowledge willingness to pay. From the perspective of the combination of conditions, there are four configurations that affect the willingness to pay for knowledge. Based on the analysis of the results of the configuration, this paper proposes specific strategies to promote the payment of knowledge by users.
