Abstract: 【Purpose/significance】Based on the knowledge co-creation theory and information adoption model, the influence mecha?
nism of online health information users' compliance intention was explored, which provides references and suggestions for improving
online health information services and user compliance effectiveness.【Method/process】Firstly, based on the information adoption
model, the user compliance intention model of online health information is constructed from the perspective of knowledge co-creation.
Secondly, the topic of tooth whitening in zhihu Q&A community was selected as the background material to design the factorial experi?
ment of 2 (information type of treatment scheme: conservative and emerging) * 2 (information quality: high and low) * 2 (source cred? ibility: high and low). Finally, SmartPLS 3.0 software was used to analyze the collected 408 valid questionnaire data to test the effec? tiveness of the model.【Result/conclusion】The quality of health information and the credibility of information source positively affect the information usefulness and information asymmetry, the information usefulness and information asymmetry have significant influ? ence on the user compliance intention.The type of health treatment scheme plays a contingency effect in the paths of information asym? metry and user compliance intention, information usefulness and user compliance intention, and the moderating effect of user involve? ment.【Innovation/limitation】Two factors, information asymmetry and user involvement, were introduced to explore the influence mechanism of user compliance intention of online health information and its management implications. However, the research object was limited to college students, and subsequent research should also pay attention to the mechanism of user compliance in knowledge co-creation in online health community。
