Abstract: 【Purpose/significance】Analyzing the formation mechanisms of value co-creation among government social media users from the perspective of psychological empowerment holds significant value in promoting the realization of the social governance con⁃ cept of "community building, communal governance, and shared benefits".【Method/process】This study took government anti-fraud propaganda as an example, integrated multi-disciplinary theories, built the influence mechanism model of user value co-creation, col⁃ lected data through a questionnaire survey, and analyzed the data using PLS-SEM and fsQCA【. Result/conclusion】PLS-SEM results show that social support and user engagement have a positive and significant impact on psychological empowerment, and psychological empowerment has a positive and significant impact on civil journalist and information protection behavior. Psychological empowerment plays a significant mediating role in the influence of social support and user engagement on value co-creation. QCA results confirm that "altruistic" civil journalist behavior needs more combination of conditions to trigger a high level of state, "egoistic" information protection behavior can be triggered by relatively fewer conditions, and psychological empowerment is the core condition of each path. 【Innovation/limitation】This paper analyzes the causes and consequences of psychological empowerment, and reveals the formation mechanism of value co-creation of government social media users. Future studies will consider other factors to explore the generative mechanisms of value co-creation from a more comprehensive perspective.
