[Objective] This paper tries to explore the dissemination mechanism and the equity issues of online medical crowdfunding. [Methods] First, we analyzed the diffusion process of medical crowdfunding. Then, we used the SEIR model to study the participants' characteristics and their decision-making behaviors. Finally, we developed the diffusion model of medical crowdfunding based on NetworkX and examined it with simulation experiments. [Results] We found that the node degree of the initiator, the appeal of the project, and the network structure affected the propagation speed and scope of the project. In the equity of financing, the node degree of the initiator, the appeal of the project, and individual wealth affected the amount of fundraising with correlation coefficients of 0.49, 0.47 and 0.63. We also found the “rich got richer” effects and the individual contribution did not reflect the “fixed ratio” way. [Limitations] The model considers few demographic characteristics, such as gender, age, occupational background, etc. [Conclusions] The proposed model could effectively simulate the diffusion process of medical crowdfunding projects on social media, which also explores their fundraising ability and the financing equity issues.
