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》中被明确规定为适用于市町村的地方一级，在讨论日本的“豆制”问题时也经常被提及。因此，我们认为，这一原则目前已经确立，我们的研究重点应该放在这一原则的具体实践上。我们的研究结果发表在《欧洲分权改革的新潮流》一书中，研究对象是欧洲9个国家（德国、英国、西班牙、法国、意大利、瑞士、比利时和瑞典）。本书计划于今年7月出版，其结论是：（1）地方分权原则是强化地方在中央与地方关系中的地位的重要概念之一。(2)这一原则有望扩大到地方或市一级的适用，但其司法意义仍不明确，因此，这一问题目前正处于审查阶段。(3)关于引进“都说”的讨论，在日本国内还需要进一步的宣传运动，我们计划进一步开展研究，对该原则进行更深入的探讨，并阐明今后在欧洲和日本的具体情况下如何适用该原则。

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.
