A CITY IN MOTION: TIME-SPACE ACTIVITY AND MOBILITY PATTERNS OF SUBURBAN INHABITANTS AND THE STRUCTURATION OF THE SPATIAL ORGANIZATION OF THE PRAGUE METROPOLITAN AREA

This contribution attempts to reveal the relations between new suburban areas and other parts of the Prague metropolitan area by investigating the time‐space activity and mobility patterns of the inhabitants of newly built suburban districts. The focus on some aspects of the everyday life of people in new suburbs helps us to identify the impact of suburbanization on the changing geography of the metropolitan region and to better understand how the spatial organization of the Prague metropolitan area is produced, reproduced and transformed. We use several interrelated concepts, which serve the theoretical foundation of our work, namely time geography, structuration theory and the post‐communist city. The empirical data utilized are primarily based on 262 diaries completed by eighty‐eight individuals from thirty‐eight households, accompanied by household questionnaires and interviews with the heads of households. The research confirmed the implicit, generally unspoken view that new suburbs in the Prague metropolitan region are heavily dependent on the core of the metropolitan area for the provision of jobs and services. However, newly built suburban shopping facilities to some extent disrupt this pattern, keeping some daily activities of inhabitants within the suburban zone. In addition to empirical observations, the key purpose of this contribution has been to discuss and apply time geography concepts and methods to the research of urban restructuring, and to understand the structuration of metropolitan spatial organization.     

Population Distribution and Spatial Structure in Transitional Chinese Cities: A Study of Nanjing

Two geographers use population surface model techniques to analyze the distribution of population in Chinese cities. Focusing on Nanjing, they utilize detailed urban land use and building distribution data to develop a productive alternative method to reveal spatial variations in the distribution of inhabitants. The findings indicate that despite suburbanization, Nanjing remains a compact city with a population density that declines rapidly as distance from its central business district increases. Also, suburbanization has been limited to an inner area where population is densely distributed while commercial and office development is less prominent. Lastly, commercial activities influence the distribution of urban inhabitants and suburbanization more significantly than industrial development in suburbia.

Re-emergence of Suburbia: The Case of Izmir Turkey

In Turkey, suburbia has become a subject of debates since the 1990s relative to the reconfiguration of urban environments due to transnational economic relations, formation of new upper income groups, social polarization and changing consumption habits. With the help of a case study in the city of Izmir, this paper examines the extent of suburbanization in Turkey in relation to the theoretical works about this subject. The studies have shown that the emergence of suburbia in Izmir goes back to the periods of integration to the capitalist economy during the seventeenth century. Meanwhile, the Anglo-Saxon type suburbia in Izmir has reemerged especially in the recent decades and along the motorways to the city. However, this paper claims that these areas are not fully established in the case of Izmir due to costs of suburban life and lack of social and infrastructural facilities.     

A city transformed: manufacturing districts and suburban growth in Montreal, 1850–1929

This paper examines the development of Montreal's industrial geography between 1850 and 1929. It is argued that a decisive feature of the evolution of the city's industrial and social landscape was the emergence of industrial districts on the moving urban frontier. The formation of new suburban districts and the reorganization of existing industrial districts were part of a developing urban spatial division of manufacturing. Three critical features underlay the restructuring of Montreal's industrial geography after 1850. Waves of industrial expansion and the development of a range of production trajectories altered the parameters of location within the city. Working-class suburbanization provided the requisite labour force for firms locating on the periphery. Local political and economic alliances created the physical, ideological and legal structures for suburban industrial growth and the rearrangement of the urban fabric.     

GENERAL EQUILIBRIUM ANALYSIS OF URBAN SPATIAL STRUCTURE. THE PORT-CITY MODEL RECONSIDERED*

In this paper, I consider a general equilibrium urban spatial structure in the setting of a port city by adopting Cobb-Douglas type functional forms for production and utility functions. Unlike previous port-city models, this one can generate four land-use patterns, that is, (1) monocentric, (2) completely integrated, (3) partially integrated (with integration at the center), and (4) partially integrated (with integration at the urban fringe) land-use patterns, and the last pattern suggests a new explanation of suburbanization of employment. The existence and uniqueness of each land-use pattern is proven in a simple constructive way.     

郊区化背景下北京市民城市中心商业区的利用特征

通过微观层面上对北京市居民中心商业中心消费行为的调查,分析郊区化背景下城市中心商业区发展现状,通过市民对城市中心商业区利用特征及其所反映的中心商业区发展问题来认识城市商业空间的变化。虽然城市中心传统商业区仍然在北京市居民消费中保持着重要地位,但是其购物空间已经表现出逐渐向迅速发展的近郊商业区转移的趋势;同时,随着新业态的迅速发展和私家车的普及,中心商业区将面临越发严峻的挑战。     

1990年代以来沈阳市就业结构的空间分异

依据沈阳市1990年第四次和2000年第五次人口普查数据,从中心城区、近郊区、远郊区和市辖县(市)等尺度分析其劳动力结构和行业结构的空间差异,研究发现沈阳市劳动力从原有的就业空间向新就业空间转移,郊区化现象明显,特别是第二、第三产业的从业人员明显出现郊区化现象,转移的主要地区为城市近郊区;而人口和工业的郊迁是引起这种现象的主要原因。人口、工业以及就业郊迁对沈阳城市空间结构产生作用,导致城市物质空间和社会空间发生重构。     

基于生活空间与活动空间视角的郊区空间研究框架

郊区空间已成为城市空间的重要组成部分,其研究意义逐渐凸显,需要学者立足郊区,关注郊区空间及其与城市空间的关系。本文从行为主义地理学和时间地理学的理论和方法论出发,对行为空间、生活空间、活动空间的概念进行辨析,提出了基于空间范式下的生活空间研究和基于人范式下的活动空间研究两方面研究内容。立足于郊区空间,面向居民日常生活,构建基于时空间行为研究方法论的郊区空间研究框架,基于此框架对郊区生活空间、郊区活动空间以及郊区空间的动态性进行解读和分析,试图为空间-行为互动理论的构建提供研究基础,为基于行为视角的郊区研究提供研究框架,为更好的理解郊区空间、解决郊区中存在的问题提供有效途径。     

Canadian Human Landscape Examples

Suburban city centres and office parks are among the prominent forms of suburban development in the Toronto region. Suburban city centres combine civic and business functions whereas office parks were designed to accommodate business requirements. Drawing on the largest suburban municipality in the Toronto region, the City of Mississauga, this paper examines two cases: Mississauga City Centre and Heartland Business Community. Suburban city centres wish to replicate some urban qualities that generate big‐city identity whereas other parts of the suburban realm remain driven primarily by corporate considerations.     

郊区新城发展与大城市空间结构调整:松江案例

目前,我国正处在城市化快速推进阶段,为突破既有城市结构对城市发展的束缚,缓解中心城区的人口、就业、交通、环境等压力,优化城市经济结构,许多城市正在积极拓展新的发展空间,大城市地区的新城建设更是如火如荼。上海自早期的卫星城建设开始,到近期的"一城九镇",再到最近的"1966"城镇体系规划建设框架,一直试图通过郊区城镇的建设和发展来疏解中心城区的巨大压力。特别是最近10年,松江作为上海大都市郊区重要城镇的规划建设,对突破上海中心城区"一核独强"的空间结构所产生的影响在新城建设中颇具典型的意义。本文试图通过松江新城"次核"发育、松江新城的城市功能演化、松江新城人居环境建设三个方面的剖析,探讨新城建设与城市空间结构演化的互动关系,以在宏观上更好地认识和把握新城对城市发展的影响,以期对上海或国内其他大都市区郊区其他新城的建设和多中心城市空间格局的形成有所裨益。     

中关村科技园区在北京城市空间扩展中的地位与作用

21世纪是知识经济的时代,各种类型的高新科技园区应运而生,研究高新科技园区的发展对城市空间扩展的影响有时代意义。中关村科技园区是北京发展知识经济的基地,在科技园区中具有代表性,本文从中关村科技园区的用地规划、产业规划、交通规划、环境规划入手,分析中关村科技园区建设在北京城市空间扩展中的地位与作用。结果表明,中关村科技园区的建设将加速北京向郊区化方向发展,同时吸引高素质人才聚集西北地区,其中心区有可能成为北京城市的副中心,从而促进北京大都市多中心格局的形成,同时诱发产业轴线空间发生战略性转移,使得西北-东南轴向成为北京大都市最重要的空间扩展轴。在上述分析的基础上,本文对北京市总体发展规划提出了建设性的修订意见。     

西方社会空间视角下的郊区化研究及其启示

作为一种分散型城市化,郊区化始于20世纪20年代,盛于二战后的发达国家。西方早期的郊区化研究主要集中在郊区化的发展浪潮,郊区化的界定方法、发展机制、后果和政府调控等方面,90年代所提出的"新郊区化"概念将郊区化与边缘城市、郊区次级就业中心的发展联系在一起。21世纪以来,社会空间成为西方郊区化研究者最关注的话题。本文基于近年西方学者关于郊区化研究的最新文献,从郊区化与居住空间重构、郊区化与住房选择和分异、郊区化与居民通勤行为、郊区化与居民生活空间、郊区化的社会影响等方面总结了西方学者在社会空间视角下的郊区化研究方面所取得的研究成果。然后,分析了西方研究议题转变和研究方法创新对中国郊区化研究所带来的启示。最后,从研究视角拓展、定性方法应用、微观机理探讨、多重互动模式建构等方面对未来中国郊区化的研究进行展望。     

The specifics and spatial structure of circular migration in Russia

Abstract

This article aims at distinguishing recurrent population movements within the territory of the Russian Federation between urban localities of different sizes and rural areas in connection to the processes of urbanization, suburbanization, and de-urbanization. Incomplete urbanization and the strong polarization of socio-economic space in Russia have resulted in two powerful contradictory population flows: centrifugal seasonal sub- and de-urbanization and centripetal labor migration from rural and small towns to large urban centers. The article discusses three forms of recurrent population mobility in Russia: (1) daily commuting of urban and rural inhabitants within metropolitan areas; (2) commuting to large cities and their suburbs for long-term employment intervals (weekly, monthly, etc.), (3) second-home commuting to countryside dachas. Unfinished urbanization in Russia not only attracts rural and small towns’ population to major cities but also keeps it within the latter. It slows down the real de-urbanization and induces specific dachas (second-home) suburbanization/de-urbanization, with these processes being closely interrelated. An opportunity to earn money in cities together with the impossibility of moving to major centers due to expensive housing encourages households to remain in small towns and rural areas. Meanwhile, inhabited rural localities (even ones distant from cities) attract seasonal population (dachniks).     

Suburbanization and sprawl in post-socialist Belgrade and Sofia

The goal of this research is to examine the processes of suburbanization and sprawl in two post-socialist capital cities in Southeast Europe – Belgrade, Serbia and Sofia, Bulgaria. Our analysis begins with a survey of relevant historical developments in the two cities, which illustrates the impact of major political, economic and social drivers on urban development processes and form. We follow this with an empirical study aimed at identifying contemporary features of peri-urban processes occurring in the two cities. Specifically, we explore spatial patterns, general population trends and changes in urban densities. Our study confirms earlier observations by other researchers that processes of suburbanization are occurring in Belgrade and Sofia. Yet this research goes further and emphasizes the specific combination of conditions inherited from the era of state socialism and the features of South-east European urban culture. Thus regarding the form of urban expansion, we observe relatively weak trends of sprawl with strong local specifics. On this basis, we discuss our empirical results with the objective of identifying the specifics of studied processes in Belgrade and Sofia as a grounds for the articulation of an appropriate policy framework.     

基于生命历程视角的郊区居民迁居行为重构——以北京回龙观居住区为例

城市居民迁居行为是城市地理学的重要课题,但以微观手法研究郊区居民迁居行为重构尚不多见。本文基于质性研究方法,以位于北京郊区的回龙观居住区为例,以微观的手法对城区拆迁居民、经历体制转型的中老年人、北京本地年轻人以及外地来京年轻人的迁居历程进行解读,寻找经济、社会和制度变革与个体生命历程的交集,进而洞察郊区居民迁居的一般性特征。在此基础上,从迁居机会供给、住房需求、住房获取能力、迁居决策4个方面归纳郊区居民迁居行为重构特征,并从宏观、中观、微观3个层面阐释重构机制。对郊区居民迁居行为重构的研究,有助于理解北京城市空间重构及郊区化进程。     

上海城市功能与人口郊区迁移的特征和影响分析

随着我国进入城市化发展高峰期,城市产业功能和人口的郊区化趋势日益显著,速度不断加快。在我国特有的城乡二元化管理体制下,郊区化过程中城市人口与产业功能的郊区迁移对城市结构转型以及郊区城市化具有怎样的影响仍需要进一步探讨分析。本文根据区县一级的城市建设与人口等相关统计数据,总结近十年来上海城市功能和人口郊区迁移过程中城市空间结构转型的主要特征,分析郊区化对郊区人口城市化、城镇建设与产业发展的影响作用,辨明其中存在的主要问题,并从城市功能布局合理化和促进郊区发展的角度出发提出对策建议。     

广州城市内部居住迁移空间特征及其影响因素研究

居住迁移是家庭居住消费的空间调整过程,也是城市重构的基础动力,是西方地理学、规划学和社会学研究的主要内容。利用2001年和2005年在广州市进行的家庭住房问卷调查结果,文章分析了居住迁移空间特征、方向特征以及居住迁移方向的影响因素。分析结果显示,广州市居住迁移空间以就近迁移为主,在同一行政区范围内和邻近行政区间的迁移比重非常高,但从阶段演化来看,就近迁移有弱化趋势。迁移方向以老城区内和外围区内的迁移为主,其次为以老城区向外围区迁移。住房产权、家庭生命周期、家庭收入和迁移时间对居住迁移方向的影响显著,居住郊区化与住房自置率提高有关;单位房和房管局房建设是郊区化的主要动力之一。     

90年代重庆零售商业离心化研究

本文以重庆市近郊区为研究区域,通过对近郊区与中心区社会商品零售额总量和增长率的比较以及对近郊区零售商业中心的特征分析,发现90年代中期开始出现商业离心化的迹象。商业离心化的出现是宏观环境以及中心区与近郊区推拉力机制共同作用的结果。目前的商业离心化尚处于萌芽阶段,是市场经济下的自觉行为,但不同于计划经济下的均衡分布,离心化发展速度较慢,主要发生在各郊区商业中心,中心区的商业优势仍然很突出。商业离心化势不可挡,近郊中心与中心区的竞争将更加激烈,中心商业区和郊区商业中心应各有侧重地发展     

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。     

基于GPS数据的北京郊区就业者工作与通勤行为特征研究——以上地信息产业园为例

城市空间快速扩张及郊区中心的崛起,带来多中心城市结构的演变及一系列城市问题。已有研究较少针对对郊区就业者的工作与通勤行为,未能全面地反映新职住“空间错位”。本文基于2012年对北京上地就业者的日常活动与出行调查数据得出以下结论：①主动郊区化的侧面通勤者体现出典型的郊区生活方式： “朝九晚六”、加班明显,生活活动空间更加广域化。②在郊区化过程中被动调整的逆通勤者职住距离最长、依赖公共交通通勤、“早出晚归”、错峰出行、生活活动空间呈现以家和工作地为主的“两极化”特征。③郊区中心内部相对职住接近的就地通勤者,在享受工作与通勤便利性（如职住接近、“晚出早归”）的同时活动空间高度隔离集中在郊区中心。
