Urban built environment in modern Japan established by public agencies

主要研究成果如下：（1）回顾了西方国家地理学和其他社会科学研究所建立的城市土地开发过程模型。这些模式主要是基于现有的社会理论，如新古典主义经济学、韦伯社会学、马克思主义经济学以及吉登斯或列维-斯特劳斯的结构主义。基于代理人的模型可以很好地理解角色和许多行为者或代理人之间的关系，Ganderton的结构模型可以解释包括代理人和其他社会，经济和文化因素在内的整个发展过程的结构。(2)A在日本的整个现代时期，城市规划和关于土地使用变化的法律的分区对城市建成环境的建立（例如基础设施）具有很大影响，已经在城市地区实施。公共机构的意图往往以城市规划或法律的分区的形式表现出来，它们指导并间接影响着城市建成环境的建立。城市规划的采用在二战前已遍布大都市区的城市和地方中心城市，并展示了当时的城市体系。（3）选取了旭川、松山、别府三个样本城市。为了评估公共机构对设施建成环境的作用，收集和分析了许多显示法律的分区和基础设施建筑物过渡的论文和地图。

Results of the research project are as follows ;(1)Land development process models in urban area which have developed in academic society of geography and other social sciences of western countries are reviewed. These models are mainly based on existing social theories such as neo-classical economics, weberian sociology, Marxist economics and structuralism of Giddens or Levi-Strauss. Rolls and relationship between many actors or agencies are well understood in agency-based model, and whole structure of development process including agencies and other social, economic and cultural factors, is explained in structural model of Ganderton.(2)A city planning and a legal zoning on land use change which has much influences on establishments of urban built environment, for example infrastructures, has been enforced on urban areas throughout modern period of Japan. The intentions of the public agencies tend to be expressed in the form of a city planning or a legal zoning, and they directory and indirectly affects the establishments of urban built environments. Adoptions of city planning have been spread out over cities of metropolitan areas and the local central cites before Second World War, and displayd the urban systems at that time.(3)Three sample cities, Asahikawa, Matsuyama and Beppu, have been selected. In order to evaluate the roll of public agencies on establishments built environment, many papers and maps displaying the transition of legal zoning and buildings of infrastructures have been collected and analyzed.
