In this research project, I employ the nationally representative individual medical claim data, the Fact-finding Survey on Medical Assistance and the Survey of Medical Care Activities in Public Health Insurance from 2001 to 2007, conducted by the Ministry of Health, Labour and Welfare in Japan and examine the differences in the demand and supply of the medical care between the beneficiaries of the Public Assistance system and the enrollees of the public health insurance systems. I find that medical suppliers provide unnecessary inpatient and outpatient treatments to the beneficiaries and enrollees in response to the medical fee reductions and that the beneficiaries more visit medical institutions than the enrollees in their second and subsequent months.

在本研究项目中，我采用了具有全国代表性的个人医疗索赔数据，即日本厚生劳动省2001年至2007年医疗援助实况调查和公共健康保险医疗活动调查，考察了公共援助制度受益人和公共健康保险制度参保人之间医疗保健需求和供给的差异。我发现，医疗供应商为了减少医疗费用，向受益人和参保人提供不必要的住院和门诊治疗，而且受益人在第二个月和以后的几个月里比参保人更多地去医疗机构。
