深圳居民夜间消费活动的时空特征

本文以深圳居民日常行为问卷调查及实地访谈资料为基础,聚焦于国内地理学研究尚处空白的居民夜间消费活动,分析了城市居民夜间消费的总体特征与时空特征。深圳居民的夜间消费活动普遍比较活跃,并以购物、餐饮及娱乐休闲为主;但平均消费时间并不长,消费频率也较低;西方国家城市中出现的夜间消费深夜化现象并不明显。夜间消费活动表现出明显的随距离衰减现象,并且形成居民夜间消费活动的圈层结构,即1km圈层的基本空间、5km圈层的主要空间和10km圈层的日常空间。另外,不同夜间消费活动类型的空间分异也比较显著,形成夜间购物（平均距离为2km）、夜间餐饮娱乐（平均距离3km）、夜间体育健身与商务应酬（平均距离3～5km）的空间结构。

The study on the temporal-spatial characteristics of the consumer activities of Shenzhen residents at night

Since the 1970s, there has been an obvious tendency in western countries to approach to humanistic, micro-level and multidisciplinary studies of human geography, hence providing a more comprehensive understanding of their increasingly diversified cities.This paper is concerned with consumer activities at night, which has long been neglected in geographical studies in China. Based on the questionnaire survey and interviews on consumer behavior of Shenzhen residents, the authors analyzed the general characteris tics of consumer activities at night, especially their temporal-spatial charact eristics. Further, the author made correlated analyses in terms of residents' a ttributes. The characteristics of consumer activities of Shenzhen residents at night can be summarized as follows: (1) The consumer activities of Shenzhen resi dents at night flourish in general and the main types of consuming activities are shopping, eating & drinking and entertainment; (2) the average consuming time does not last long and consuming at deep night happens less frequently compared with that in western countries; (3) the frequency of consuming activities at night is relatively low; (4) the spatial characteristic of consumer activities at n ight is according to the distance decaylaw and can be abstracted as a concentri c-circle-structure: the inner circle with a radius of 1km is the primary space,the middle circle with a radius of 5km is the major space and the outer circle with a radius of 10km is the daily space; and (5) the activity space of different types of consumer activities at night also varies: the inner circle with aver aged 2km radius is shopping space, the middle circle with averaged 3km radius is eating, drinking & entertainment space and the outer circle with averaged 4.5- 5km is business and activity in gymnasium space.
