进城务工人员购物活动时空特征解析——以南京市为例

以南京市进城务工人员为研究对象,在宏观把握其社会经济及空间概况的基础上,分析其线下购物的时空特征及典型时空轨迹。结果表明:(1)时间特征上表现为以低频购物为主;购物时段集中在上下班途中及休息日下午;购买低等级商品时对出行时间较为敏感,约为10 min;购买高等级商品时对出行时间不太敏感,多集中在1 h内。(2)空间特征上表现为购买低等级商品时对出行距离较为敏感,约为0.5 km,购物活动空间较为集聚;购买高等级商品对出行距离敏感性较低,购物出行空间较为分散。(3)时空轨迹上表现为单纯购物活动的购物场所及出行空间等级均较低,购物时长较短,购物时段的连续性在工作日要高于休息日;多目的购物活动的购物场所及出行空间等级则较高,购物时长较长,购物时段集聚度较高。

Spatial-temporal Characteristics of Shopping Activities of Migrant Workers:A Case Study of Nanjing City

Taking migrant workers in Nanjing as the research object,396 valid questionnaires were distributed in 2019 to focus on the temporal-spatial characteristics of their offline shopping.The time characteristics of shopping activities are as follows:the frequency of migrant workers’shopping activities is relatively low and the shopping occurs mainly during the periods of commuting or the afternoon of rest days;when purchasing low-grade commodities,it is sensitive to travel time,which is about 10 min,while when purchasing high-grade commodities,it is not sensitive to travel time,which is mostly concentrated within 1 h.The spatial characteristics of shopping activities are as follows:when purchasing low-grade commodities,it is sensitive to the travel distance,which is about 0.5 km,and the space for shopping is relatively concentrated.However,when purchasing high-grade commodities,it is less sensitive to travel distance,and the space for shopping is relatively scattered.The characteristics of typical spatial-temporal trajectory are as follows:the places and the spatial hierarchy of pure shopping activities are lower,the shopping time is shorter,and the continuity of shopping period is higher on weekdays than on rest days.The places and the spatial hierarchy of multi-purpose shopping activities are higher,the shopping time is longer,and the shopping period has a high degree of agglomeration.
