不同模式下城市郊区居民工作日出行行为的比较研究——基于北京与广州的案例分析

本文选择北京、广州的两个典型社区,分别作为转型期中国城市居住郊区化"政府主导模式"与"市场主导模式"的代表案例,基于两个社区的活动日志调查数据,比较两个社区居民的工作日出行行为,以此探究居住郊区化模式对居民出行行为的影响,在国内已有时间地理学研究基础上进行城市间直接比较研究的尝试。研究发现:政府主导的居住郊区化模式为居民提供了较完善的活动机会与便捷的出行环境,但并没有避免职住空间错位;市场主导的居住郊区化模式无法提供完善的活动机会与良好的出行环境,居民日常活动高度依赖于内城。

A COMPARATIVE STUDIES OF SUBURBAN RESIDENTS' TRAVEL BEHAVIOR ON WEEKDAYS UNDER DIFFERENT SUBURBANIZATION MODES: A CASE ANALYSIS OF BEIJING AND GUANGZHOU

While a number of studies have shed light on the process, mechanism, and spatial outcomes of suburbanization in Chinese cities, few of them focused on suburban residents' daily lives and thus failed to make sense of how suburbanization may impact on resident's quality of life. On the other hand, the suburbanization in urban China is quite different and much more complicated than that in Western cities as it was initiated by governments in 1980s while driven by market in last the decades, and influenced by various housing policies in different cities of China, which resulted in a variety of suburbanization modes and suburban space. This paper reports an attempt to address the impacts of different suburbanization modes on residents' daily lives through a comparative studies of suburban residents' travel behavior under the background of different residential suburbanization modes, namely government-oriented mode and market-oriented mode. We carry out a case analysis of two typical communities in Beijing and Guangzhou resulting from the activitytravel diary surveys in two cities in 2007, from the perspective of trip frequency, trip distribution, temporal rhythms and modes of transport. The result shows that travel behavior of two cases shares similarities with low tour frequency, long commute distances, inner-city-oriented commute directions, and high level of motorization, and an average of 1.7 hours per day spent on trips, which reflects the constrains of jobs-housing mismatch on residents' travel behavior.
