交通可达性对居住地选择的影响--以成都市为例

为了解新型城镇化战略下大城市中心区居民外迁至卫星城时的居住地选择行为特征及偏好，选取卫星城居住地周边学校、医院、商业设施、轨道交通车站及到中心区交通可达性作为主要变量。根据家庭成员组成特征将样本家庭划分为5类，对比分析不同家庭居住地选择行为特征及偏好。结合家庭社会经济属性形成了一套包含8种情景的正交设计组合问卷，对成都市中心区居民进行意愿调查，并建立Logit模型对居住地选择行为进行分析。结果表明，学校、医院等主要服务设施的交通可达性及家庭自身属性均对中心区居民外迁行为存在显著影响，同时定量分析各变量对居民选择外迁意愿的影响程度，最后提出有助于中心区人口疏解到卫星城的交通政策和措施建议。

Impact of Transportation Accessibility on Residence Choice:Taking Chengdu as an Example

To learn residence choice behavior and preferences of residents living in downtown when they move into satellite cities under New Urbanization Strategy, this paper takes accessibility of hospital, school, commercial amenity, rail transit station, and downtown as studied variables. According to family characteristics, the paper divided families into 5 groups to compare the characteristics and preferences of each family group. According to family's social and economic characteristics, a comprehensive orthogonal SP questionnaire containing 8 scenarios is proposed. Based on the survey of downtown residents in Cheng-du, the paper develops a Logit model to study residence choice behavior. Results reveal that the choice be-havior of downtown residents of moving to satellite cities are significantly impacted by the accessibility of service facilities, such as school, hospital, and family characteristics. The effect level on migration proba-bility is also analyzed. Finally, the paper proposes transportation development polices and measures for promoting migration from downtown to satellite cities.
