Outline of Final Research Achievements |
This research seeks to shed light on policy coordination for the elimination of international double taxation in Europe, the Americas (particularly the United States), and Asia (particularly Japan), as well as the tensions in the exercise of taxing rights among three regions as seen from the process of formulating a model Double Tax Convention, through analysis of original documents from international organizations and the opinions of key figures. In the case of Japan, the research analyzed domestic tax policy after the enactment of the Income Tax Act in 1887 and international tax policy from around 1907, particularly policy coordination within the League of Nations since the 1920s. The originality of this research lies in the unearthing of original materials.
Part of the research findings have already been made public through academic presentations and editorial publication both at home and abroad.

Academic Significance and Societal Importance of the Research Achievements |
本研究の研究成果の学術的・社会的意義は、今日OECD/IFを中心に活発に政策協調と国際条約締結・国内法改正が進みつつある一連のBEPSプロジェクトの理論的背景と、BEPSプロジェクトの各国への影響を法理論的視点から措定することが可能になる、という点にある。 すなわち、BEPSプロジェクトでは頻繁に「100年来の大改正」であることが喧伝されているが、実はそのようなものではなく単に産業構造・経済構造の変化に応じた調整に過ぎないことが、本研究の成果を背景として照らし合わせることで明らかになった。また、史料調査を徹底したため、従来の通説的理解に誤解があることがいくつか明らかになった。
