Abstract: Sharing medical platform can help alleviate social problems such as uneven distribution of medical resources and tensed doctor-patient relationship. However, due to the lack of an effective and sustainable cooperation and win-win model, users in two-sided market are not motivated to participate, so the platform market grows slowly and cannot bring significant economic and social value. Based on the value co-creation theory and the case of “haodf.com”, this paper constructs a model of value co-creation process of sharing medical platform and inductive value dimensions, which can not only motivate users in two-sided market to participate in a comfortable manner, thus expanding the market scale; but also promote the interaction and sharing of resources, thus maximizing the value co-created by each subject. The results show that the demand side drives suppliers and platforms to optimize service level; the platform side guarantees the interests of two-sided market users; the supply side strives to win itself and platforms a better reputation and achieve better consumer experience; sharing medical platform is fully embedded in the society, and both of them promote each other’ s development; all players co-create informational value, functional value, economic value and social value through interactions. This research provides a good answer to the question of “how a sharing medical platform realizes value co-creation”, and has theoretical contributions to the research in the field of sharing medical care and value co-creation, and also provides practical enlightenment for platform operation and industry development.
