Against the backdrop of high-quality economic development driven by the digital economy and continuous national policy improvement for digital industries and platform economies, this study focuses on the development of paid knowledge services on online Q&A communities. Taking Zhihu as the research sample, it explores the advantages and existing problems of its paid knowledge business model to provide references for the transformation and innovative development of similar online communities. This study systematically summarizes the operational mechanism and innovative characteristics of Zhihu’s paid knowledge model through literature review and model analysis, and adopts questionnaire surveys to collect user consumption data and analyze consumers’ willingness to pay and service satisfaction. The results show that by leveraging internet platforms and digital technologies, Zhihu has innovated its business model and effectively promoted digital economic value transformation. However, the platform has apparent deficiencies in the paid knowledge operation system and user consumption experience, with users’ payment behaviors influenced by multiple factors. As a typical representative of the industry, Zhihu reflects the common development dilemmas of the current online paid knowledge sector. Targeted optimization strategies can improve the operation system of online community paid knowledge services and boost the standardized and high-quality development of platform and digital industries.
