Based on Construal Level Theory (CLT), privacy calculus theory and Theory of Planned Behavior (TPB), the influencing factor model of privacy disclosure behavior of online medical platform users is constructed. The model is empirically tested by questionnaire survey. The results show that perceived risk has a negative impact on users' long-term disclosure intention, but has no significant impact on users' short-term disclosure intention; perceived income has a positive effect on both long-term disclosure intention and short-term disclosure intention, etc.
