居住空间对家庭购物出行决策的影响

利用2007年北京市民活动日志调查的第一手数据,建立了强调家庭和决策过程的嵌套Logit模型,探讨居住空间对购物出行行为的影响,并在居住空间尺度上模拟评估土地利用政策对居民购物出行优化的作用。结果表明,居住区位的差异往往导致居民通过调整其生活方式(如购物出行模式)来适应,而非直接显著影响其购物出行需求(反映在家庭购物出行频率)。居住地商业密度对购物出行频率和出行模式决策的影响均存在明显的空间分异,且需求弹性均随着商业密度的变化而变化。这说明需要针对不同区位、不同居住空间、不同出行需求弹性情况来实施不同的土地利用政策和规划,以便优化购物出行需求。同时,城市居民购物出行模式的调整优化既需要居住空间的土地利用调整也需要交通设施和交通状况本身的改善。

The Influence of Residential Space on Household Shopping Tour Decision-Making Behaviors

The relationship between urban form and non-work activity-travel has received considerable attention in the recent debates over the area of transportation, urban studies and geography.

Data for the analysis are drawn ...
