医疗市场偏离于完全竞争性市场,因此政府需要对医疗市场进行管制以减轻市场失灵。政府对医疗市场进行管制的经济目的是降低支付的成本、提高医疗服务的质量,增进医院市场的效率,但管制政策真的能达到所期望的目的吗?政府管制下医院相对效率的变化只能用事实证据来下定论。由于美国是采取联邦制度的国家,各州所采取的管制政策内容与实施的时间并不完全一致,形成一个近似科学实验室的研究环境,让研究者可以通过比较试验组与控制组的方法,分析管制政策的影响效果。
The medical market deviates from a perfectly competitive market, so the government needs to regulate the medical market to ease market failures. The economic purpose of government regulation of the medical market is to reduce the cost of payment, improve the quality of medical services, and enhance the efficiency of the hospital market. However, is the regulatory policy really able to achieve the desired goal? The relative efficiency of hospitals under government control can only change Use factual evidence to draw conclusions. Because the United States is a country that adopts the federal system, the contents of the regulatory policies taken by the states are not exactly the same as the implementation time. Therefore, a research environment similar to a science laboratory is formed so that the researchers can analyze the differences between the experimental groups and the control groups Impact of regulatory policies.
