广州市中产阶层外出购物行为的时空特征及决策因素

基于广州市中产阶层活动日志问卷调查,借鉴社会分层、行为地理学和时间地理学等理论方法,采用ArcGIS空间分析和多元Logit模型对中产阶层外出购物行为的时空特征与决策因素进行分析。结果表明:中产阶层外出购物行为呈现多样化时空特征。工作日购物时间双峰陡峭,休息日双峰平缓;工作日购物空间范围比休息日小,工作日购物活动集中在晚间近圈层(0~1 km),休息日集中在白天中圈层(1~5 km)。无论工作日还是休息日,商业设施密度是影响中产阶层外出购物行为时空决策的主要因素,工作日性别因素影响较大,休息日出行方式因素作用显著。中产阶层购物时间节奏与一般居民相差不大,但空间距离较远,其时空决策受商业设施密度影响程度更高。

Spatial-temporal Characteristics and Decision-making Factors of Middle-class Outshopping Behavior in Guangzhou City

Based on activity diary survey for middle-class residents conducted in Guangzhou,this study systematically analyzes the spatial-temporal characteristics and influence factors of middle-class outshopping behavior by referencing the social stratification,behavior geography and time geography theory as well as using ArcGIS spatial analysis and multivariate logit model.The results conclude that middle-class outshopping behavior varies spatial-temporal characteristics.The shopping time show the steep bimodal form on the working day,while the flat bimodal form on the weekend day;the shopping distance is more far on the weekend.The shopping spatial-temporal structure on the working day is different from the weekend day,and the former concentrates night nearly envelops,the latter concentrates daytime medium envelops.The density of commercial facilities is the most important factor influencing spatial-temporal decision-making of middle-class outshopping behavior on the working day and weekend day,followed by the gender on the working day and trip mode on the weekend day.Compared with ordinary people,middle-class residents have the similar time rhythm of outshopping but further space distance,meanwhile the spatial-temporal decision of outshopping behavior is affected more by commercial facilities.
