Behavioral Approach to Migration within Tama New Town

从居住环境的物质和社会两个方面对多摩新市镇内居住变化引起的人口迁移进行了分析。本研究向最近在多摩新市镇内迁居的两类抽样住户及其邻近住户发放问卷，以获取迁居原因及居住环境评价的资料。抽样家庭的平均形象具有白领特征。户主年龄在四十多岁，家庭成员人数为四人的班级。迁居的主要原因是子女的出生和成长以及对居住环境的不满。迁居家庭对房屋大小、房屋布局等与居住相关的问题的不满程度远高于迁居家庭。利用GIS对住区环境综合评价的空间分布进行分析，得出住区环境综合评价依赖于地形和各种公共、商业设施的可达性。对搬家或留下决定的Logit模型显示，搬家决定是由与居住相关的变量而不是与生活环境相关的变量（如舒适性、安全性和便利性）来决定的。

Migration caused by residential change within Tama New Town is analyzed with special reference to both of physical and social aspects of residential environment. Questionnaires were distribnted to the two types of sampled households which have recently changed residence within Tama New Town and those neighboring to them in order to obtain the data on reasons of residential change and evaluation of residential environment. The average image of the sampled households is characteristic of white-collar. class whose head of the household is in his forties and whose number of household members is four. The main reasons of residential change are attributed to the birth and growth of their children and dissatisfaction with residential environment. Moved households are much more dissatisfied with residence-relevant items such as the size of house and the plan of house than stayed-households. Spatial distribution of composite evaluation of residential environment is analyzed with GIS, so that it turns out that the evaluation depends on topography and accessibility to various, public and commercial facilities. Logit modeling on the decision to move or to stay reveals that the decision to move is well accounted for by residence-relevant variables rather than living-environment-relevant variables such as amenity, safety and convenience.
