Abstract: The establishment of medical consortia is an important measure to improve the overall effectiveness of the medical service system, and it is also the need to promote the establishment of a reasonable and orderly model of graded diagnosis and treatment. The best referral model is to make reasonable referrals between the members of the medical consortia based on the difficulty level of the disease. However, since the opportunity cost of referral is not consistent, the members of the medical association do not necessarily conduct two-way referral according to the level of disease difficulty due to the consideration of economic interests, which leads to the problem of “linked but not passable”. Based on the effective distribution principle of the cooperative game, this paper discussed the reasonable distribution method of incremental economic benefits of the medical consortia, and introduced some examples. Based on the composition structure of different medical consortia, it proposed a reasonable distribution scheme of incremental economic benefits among the members. In addition, it predicted the income distribution value by using the method of the probability graph cooperative game. This paper, combining the theoretical research of medical consortia with the theory of cooperative game, explored the solution to the referral bottleneck through the fair distribution of economic benefits, which is of practical significance.
