Urban built environment in modern Japan established by public agencies

研究成果如下：(1)对西方地理学等社会科学学会发展起来的城市土地开发过程模型进行了综述。这些模型主要基于现有的社会理论，如新古典经济学、韦伯社会学、马克思主义经济学和吉登斯或列维-施特劳斯的结构主义。基于代理的模型很好地理解了许多行为者或机构之间的角色和关系，甘德顿的结构模型解释了包括机构和其他社会、经济和文化因素在内的整个发展过程的结构。(2)日本近代以来一直在城市地区实施对城市建成环境设施(如基础设施)有很大影响的城市规划和土地利用变化的法律区划。公共机构的意图往往以城市规划或合法分区的形式表达，它们编目并间接影响城市建成环境的建立。在第二次世界大战之前，城市规划的采用已经扩展到大都市区和地方中心城市，并展示了当时的城市体系。(3)选取了旭川、松山和别府三个样本城市。为了评估公共机构在设施建设环境方面的作用，收集和分析了大量展示法定区划和基础设施建筑过渡的论文和地图。

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.
