Design of Semi-Compact City Medical Association Information Sharing Sustainable Operation Mechanism Based on Subscription Plan

Semi-compact city medical association consists of information sharing platform operator, tertiary hospitals, and community hospitals. To solve the sustainable operation problem without government funding, the platform operator provides two subscription plans: paying annually and paying per service, which integrate the value-added business benefit distribution mechanism and consider grading diagnosis and treatment. To optimize the subscription plan and investigate the decision of hospitals, the optimization theory and Differential Evolution algorithm is employed. The research shows that the introduction of subscription plans can achieve the sustainable operation of semi-compact city medical association; regulate the price of value-added medical service can promote the willingness of community hospitals and platform operator revenue. However, increase the proportion of platform operator in value-added service will reduce the sustainability of semi-compact city medical association.
