By focusing on the elderly suicide rates, this study lays out the different suicide regulation and prevention policies of three developed countries – Japan, the Netherlands, and South Korea. The main goal is to compare and analyze how these policies, with disparate ways of handling suicide, influence elderly suicide rates in relation with their countries’ respective differing suicide determinants. By applying the ‘Method for Synthesizing about Public Policies’ created by Morestin, Gauvin, Hogue, and Benoit to check the status of efficiency and of any issues of public policies, it concludes that South Korea shows promise, while Japan’s suicide rates have certainly been scaling down. Conversely, in terms of the use of euthanasia, suicide rates in the Netherlands have been continuously rising.

通过关注老年人的自杀率，本研究提出了三个发达国家（日本，荷兰和韩国）的不同自杀法规和预防政策。主要目标是比较和分析这些政策，以不同的自杀方式，如何影响老年人自杀率及其各自不同的自杀决定因素。通过应用Morestin，Gauvin，Hogue和Benoit创建的“公共政策综合方法”来检查效率状况和任何公共政策问题，得出的结论是，韩国表现出希望，而日本的自杀率肯定是缩小。相反，就安乐死的使用而言，荷兰的自杀率一直在上升。
