Outline of Research at the Start

本研究は、無子超高齢社会という共通項をもつ日本、台湾および中国の比較をつうじて、無子超高齢社会に特有の紛争とは何か、その解決システムにはいかなる特質があるのか、その背景にはいかなる社会構造の特徴があるのか、これらについて日台中間にいかなる相違があるのか、を明らかにするものである。

Outline of Final Research Achievements

This study aims to explore the following issues through a comparative analysis with Taiwan and China, both of which - like Japan - are entering a super-aged society with a growing number of elderly individuals without children:whether conflicts unique to a super-aged, childless society can arise; if so, what forms these conflicts might take; whether it is possible to construct dispute resolution systems specialized for such conflicts; and what social structural characteristics underlie these phenomena.
In China, there are dispute resolution mechanisms specifically designed for elder-related conflicts. However, the focus lies in mobilizing all available societal resources to prevent such disputes from occurring in the first place.In Taiwan, efforts are centered on establishing and promoting the use of a legal infrastructure that addresses the decline in cognitive, physical, and emotional capacities - a common trait among the elderly - to prevent conflict emergence.

Academic Significance and Societal Importance of the Research Achievements

日本、台湾、中国という東アジアの異なる法制度・社会構造を比較することにより、無子超高齢社会という新しい社会構造における特有の紛争が存在するかどうか、またその類型や特徴を分析することで、比較法研究に知見を提供する。
無子化と高齢化が複合的に進行する社会において、従来の家族・福祉・法制度では対応困難な課題に対して、新たな社会的対応の必要性を広く社会に認識させる。
