During the “Twelfth Five-Year Plan” period，Beijing Municipality has realized，as a major achievement，fast growth in resource input into the medical and healthcare undertakings. The crucial problem to be solved rests on the unsatisfactory quality and inefficiency vis-à-vis the fast growth in input. A qualitative analysis reveals the structural imbalance existing in the distribution of medical resources among different strata of medical institutions. A quantitative analysis shows the unsustainability of the growing expenditure of medical insurance. In addition to the separation between medical and pharmaceutical services，stratified diagnosis and treatment might be a feasible solution. In conclusion，the paper puts forth proposals on the construction of the medical alliance.
