Synthesis and Health Economics Approach to Aging Population and Medical Care : an Empirical analysis

该项目的主要计划最初始于1993年，名称为“日美医疗制度比较分析”。在过去六年中，前三年的阶段是关于名为“日本医疗部门的低效率及其原因：计量经济分析”的项目。过去三年的第二阶段是第一阶段的延续，但该项目是关于“老龄化人口和医疗保健的综合和健康经济学方法：实证分析”。这两个项目都是由文部科学、体育和文化部资助的。在过去的三年里，有几本出版物是在第一阶段创办的。那些在期刊上发表的论文被包括在本报告中，因为它们与第二阶段项目有关。我完成了一项关于“日本医院效率低下的计量经济学分析”的研究，该研究原本计划在第一阶段进行。此外，1998年，我是日本经济研究中心的研究成员之一，这使我能够使用除医院外日本个人医疗支出的各种微观数据。这项研究以《医疗支出自然增长报告》的名义向卫生经济与政策研究所报告。我的报告部分也包括在本报告中。最后，作为我研究活动的一部分，这份报告中的大部分研究都在国外国际会议上发表，例如美国和台湾。

The main scheme of this project was initially started in 1993 under the name of "A Comparative Analysis of Medical Systems between Japan and the U.S.During the past six years, the phase of the first three years was about the project entitled "Inefficiency in the Medical Sector in Japan and their Causes : An Econometric Analysis.' The second phase of the last three years was a continuation of the first phase, but the project was about 'Synthesis and Health Economics Approach to Aging Population and Medical Care : an Empirical Analysis." Both projects are granted from the Ministry of Education, Science, Sports and Culture.During the past three years, there are a few publications originated during the first phase. Those published papers in journals are included in this Report since they are related to the second-phase project. I was able to complete a study on "An Econometric Analysis of Hospital Inefficiency in Japan, " which was originally planned to do during the first phase. Furthermore, in 1998, I was one of the research members of Japan Center for Economic Research, that enabled me to use various micro data of Japanese individuals' medical expenditures in addition to hospitals. The study was reported to Institute for Health Economics and Policy under the name of Report on Natural increase in Medical Expenditures. My part of the Report is also included in the present report. Finally, as a part of my research activities, most studies in this report are presented at International Conference in foreign countries, e.g., U.S., and Taiwan.
