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

在一段研究期间，欧盟《里斯本条约》明确规定了“辅助性原则”应适用于地方自治市，在日本引入“地方政府斗制”问题的讨论中也经常被提及。因此，我们认为这一原则目前已经确立，我们的研究重点应放在这一原则的具体实践上。我们的研究结果见于《分权新潮流——欧洲改革》一书中，研究对象为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）。我们计划在今年七月出版这本书。研究结果表明：(1)在中央与地方政府的关系中，辅助性原则是强化地方地位的重要概念之一。(2)该原则有望扩大到地方或市一级的适用，但其司法意义尚不明确，目前该问题处于审查阶段。(3)关于引进斗书生的讨论，在日本需要开展更多的运动，使这一原则得到更广泛的宣传。我们打算进一步开展研究，对这一原则作更深入的探讨，并阐明今后在欧洲和日本的具体情况下应用这一原则的途径。

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.
