基于塞洛普圆周模型和博弈均衡的医疗规制分析

Analysis on Medical Regulation Based on Salop Model and Game Theory Equilibrium

我国公立医院凭借在医疗领域的垄断地位成为医疗市场和药品采购市场的双边垄断者,通过引入塞洛普圆周模型和博弈决策理论进行均衡分析,结果表明:在引入竞争之后医疗均衡价格将逐步降低,市场进入有利于患者效用的增加和社会福利的改善;同时,由于竞争格局的形成,公立医院的垄断地位不再,公立医院和药企之间的同盟关系也彻底瓦解。因此,政府应该取消对医疗领域的规制,放开医疗领域的进入门槛,引入民营资本进行竞争。

China＇s public hospitals have become the medical market and drug procurement market of bilateral monopoly by virtue of its monopoly position in the medical field for a long time. By introducing Salop model and dynamic game circumference decision theory,this paper shows that equilibrium price will be gradually reduced and it is in favor of increasing the effectiveness of patient and social welfare by market access after the introduction of competition in health care. In addition,because of the formation of competition,public hospitals are no longer in the state of monopoly and the alliance between public hospitals and pharmaceutical companies also crumble. Therefore,the government should abolish the regulation of the medical field,liberalize barriers to entry in the medical field and introduce the private capital to compete.
