Synthetic research of the principle of subsidiarity as a jurisprudential and political basic concept

在研究期间，“辅助性原则”在欧盟的“里斯本条约”中有明确规定，应在地方一级的市政当局中适用，在日本关于引入斗书制度问题的讨论中也经常提到这一原则。因此，我们认为，这一原则目前已经确立，我们的研究应该侧重于这一原则的具体实践。我们的结果显示在一本书《欧洲分权的新潮流-改革》中，这本书的研究对象是9个欧洲国家(德国、英国、西班牙、法国、意大利、瑞士、比利时和瑞典)。我们计划今年7月出版这本书。我们的结论是：(1)辅助性原则是加强地区在中央与地方关系中地位的最重要的概念之一。(2)这一原则有望将其适用范围扩大到地方或市政层面，但其司法意义仍不明确，这一问题目前正处于审查阶段。(3)关于引入斗书水的讨论，日本还需要更广泛地宣传这一原则。我们计划进一步开展我们的研究，对这一原则进行更深入的探讨，并澄清今后如何将该原则应用于欧洲和日本的具体情况。

During a research period "the principle of subsidiarity" is specified in the Lisbon Treaty of EU in which it should be applied in the local level of municipalities, and is often referred to also in the discussion on the problem of introduction of Doushuusei (Dou-system of local government) in Japan. Therefore we conceive that this principle is at present established and that our research should lay emphasis on the concrete practice of the principle. Our result is shown in a book New Current of Decentralization-Reform in Europe, objects of which are 9 European countries (Germany, UK, Spain, France, Italy, Switzerland, Belgium and Sweden). We plan this book to be published in July of this year.Our conclusions are: (1) the principle of subsidiarity functions as one of the most important concepts to strengthen the position of regions in regard to the relationship between the central and local government. (2) This principle is expected to expand its application to the local or municipal level, but its judicial sense is still so unclear that this problem is now in the phase of examination. (3) As to the discussion on introduction of Doushuusei, a more campaign to give the principle wider publicity is needed in Japan.We plan to develop our, research further to make a closer inquisition of this principle and to clarify the way to apply the principle hereafter in the concrete situation in Europe and Japan.
