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。     

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。     

Locational disadvantage and the spatial distribution of government expenditure on urban infrastructure and services in metropolitan Sydney (1988–2015)

Provision of public services by state governments rather than municipalities is considered an important urban governance factor preventing deeper levels of socio‐spatial inequality in Australian cities. The paper examines the spatial patterns of investment by the New South Wales state government in a wide range of services and infrastructure in metropolitan Sydney over 28 budget years from 1988/89 to 2015/16. We examined the relationship between volume and type of investment in infrastructure and services, and considered a local area's socioeconomic characteristics, distance from the central business district, and designation as a strategic site in metropolitan plans. Despite an overall redistributive approach favouring relatively disadvantaged areas, the most disadvantaged suburbs in metropolitan Sydney had significantly lower levels of investment. When funding was directed to the most disadvantaged suburbs, it was often in the form of new social housing development, reinforcing both the concentration of poverty and disadvantage in resource access. The findings suggest that this is a case of under‐investment by the state government in areas already populated by disadvantaged communities rather than a market‐driven process whereby disadvantaged households move into poorly resourced neighbourhoods.     

DIFFERENTIAL SUBURBAN DEVELOPMENT IN THE PRAGUE URBAN REGION

Numerous authors have asserted that suburbanization contributes to many problems in both suburban and inner city localities. Research of suburban development demonstrates variations in spatial patterns, the intensity of spatial processes, and the social and economic status of new suburbanites. While some forms of suburban development could cause serious problems throughout the urban region, other forms could be perceived as processes improving the quality of life in suburbia. This paper seeks to investigate different types of suburban development in the Prague urban region over the past fifteen years of transformation. The focus of my interest is residential suburbanization, which is one of the most significant spatial processes today in the settlement systems of post‐socialist countries. The theoretical part of the contribution deals with the differentiation of spatial processes changing the suburban zone. Here I discuss the concepts of several processes of suburban development and their distinctive impact on both suburban and inner city localities. The empirical part of the contribution is based on an analysis of migration flows in the various localities of the Prague urban region in the period 1995 to 2003. I attempt to describe the magnitude and spatial patterns of suburbanization and the composition of migrants to suburbia. The paper concludes with a discussion about the possible future development of suburbanization in the Prague urban region.     

SPRAWL,BLIGHT, AND THE ROLE OF URBAN CONTAINMENT POLICIES: EVIDENCE FROM U.S. CITIES

U.S. post‐war suburbanization has reshaped the spatial pattern of growth in many metropolitan areas, with population and employment shift toward the suburbs resulting in the urban decay of central cities. This being the case, the adoption of adequate anti‐sprawl policies should lead to a reduction in city blight. Availability of detailed blight measures at the city level enables us to undertake a novel empirical analysis to test this hypothesis. The empirical specification presented here identifies the specific impact of more stringent anti‐sprawl policies adopted at the metro level, proxied by the adoption of urban containment policies, on city blight. Results indicate that the adoption of such policies has effectively contributed to the reduction of downtown deterioration.     

An Approach to Urban Dynamics

Spatial cycles that are general to the urbanization process have been widely observed in the developed countries. These include (a) the decline of large agglomerations and the emergence of medium-sized municipalities, and (b) population decreases in the core and population increases in the suburban parts of the metropolitan area, followed later by contrasting increases in the core and decreases in the suburbs. In this paper, we formulate a mathematical model for such spatial cycles of the urbanization process as those mentioned above. Based on this model, we ascertain some general characteristics of these cycles of urban dynamics. From our findings, we can propose a long-term strategy for the urbanization process.

Estimating Rapidity of Change in Complex Urban Systems: A Multidimensional,Local‐Scale Approach

This study illustrates an exploratory approach based on a Multiway Factor Analysis (MFA) to estimate rapidity of change in complex urban systems, based on “fast” and “slow” variables. The proposed methodology was applied to 18 socioeconomic indicators of long‐term (1960–2010) transformations in 115 municipalities of Athens’ metropolitan area (Greece), including demography, land‐use/planning, and urban form and functions. Athens was regarded as a dynamic urban area with diversified structures and functions at the local scale, expanding through a self‐organized pattern rather than a centralized planning strategy. Athens’ urban system was described using nine supplementary (topographic and territorial) variables and 30 independent indicators assessing the local context in recent times. Exploratory data analysis found an increasing connectedness and redundancy among socioeconomic indicators during the phase of largest urban expansion (1960–1990). Only the rate of population growth was classified as a “fast” variable for all five decades investigated. The overall rapidity of change was higher in 1960–1970, 1980–1990, and 2000–2010, decades that coincided with specific phases of urban expansion driven by migration inflow, second‐home suburbanization, and Olympic games, respectively. Rapidity of change was high for functional indicators during all five decades studied, while demography indicators changed more rapidly in the first three decades and land‐use/planning indicators in the last two decades. Rapidity of change was highest in peri‐urban municipalities with a highly diversified economic structure dominated by industry. Our methodology provides a comprehensive overview of the transformations of a complex urban system, quantifying low‐level indicators that are rarely assessed in the mainstream literature on urban studies. These results may contribute to design policies addressing complexity and promoting resilience in expanding metropolitan areas.     

Contagious Social Practice?

This paper explores the usefulness of spatial innovation diffusion theory for understanding the observed evolution of the social practice of attaining public support as a substitute for working. The empirical example chosen is sick leave. Several European countries have experienced a striking increase in costs for sick leave during the recent years, nowhere however as dramatic as in Sweden. Public costs for sick leave have doubled since 1997 while general health and life expectancy continually improve. No more than a small percentage of this change can be assigned to compositional changes in the population and labour market with respect to age, sex, education, location and sector of employment. Neither has economic benefit conditions changed substantially during this period. What essentially remain, as possible explanations, are changes in attitudes and practices among beneficiaries and physicians. One can observe substantial regional differences in the level of sick leave and apparent traces of spatial autocorrelation in the pattern. The spatial diffusion hypothesis was examined by help of a multivariate analysis based on socio‐economic panel data including sick leave benefits and location for each individual in the labour force 1996–2000. The analysis indicates that the neighbourhood effect is substantial on the local (290 municipalities) and the regional (21 counties) level. Largely, the regional diffusion effect remains when also controlling for more persistent average differences between counties. A semi‐public spatial attitude diffusion process, mainly operating at municipality and county levels, seems to be responsible for a substantial part of the observed increase in cost for sick leave in the period 1996–2000.     

Determinants of Residential Location Choice: How Important Are Local Public Goods in Attracting Homeowners to Central City Locations?*

Abstract. A hybrid conditional logit choice model is estimated using data on the characteristics and destination of homeowners who engaged in intrametropolitan moves among 17 school districts within the Columbus, Ohio area in 1995. The model is used to test the relative influence of local fiscal and public goods versus household‐level characteristics in determining household location choices across central city and suburban school districts. Results provide evidence of both a “natural evolution” of households to the suburbs, due to job location, residential filtering, and household income and lifecycle effects, and “flight from blight,” due to lower school quality, higher crime levels, and lower average income levels in the city. In comparing the magnitudes of these variables, we find that school quality exerts the strongest influence: a 1‐percent increase in the school quality of the city district increases the probability of choosing a city residence by 3.7 percent. In contrast, the effects of household income and other individual characteristics are relatively modest. The findings provide support for a “flight from blight” suburbanization process that is dominated by differences in neighborhood quality between the city and suburbs. An implication is that investments that promote central city development and reduce suburbanization are justified on efficiency grounds if negative externalities are generated by increased concentration of poverty, crime, and low school quality.     

La ségrégation économique comme un phénomène complexe : une analyse spatio-temporelle du cas montréalais

Economic segregation, or residential inequalities based on income, is a complex spatial process. It is associated with structures which arise at certain scales and which evolve in time. In this paper, we analyse the evolution of economic segregation in Montréal from 1980 to 2000. This analysis is based on household's income and on their distribution within the residential space from four scales: households, census tracts, municipalities and some radio-concentric zones. Results confirm that the spatial organisation of economic segregation is scale dependent. More precisely, local inequalities are growing more rapidly but this trend does not prevent the consolidation of metropolitan-sized clusters. Moreover, results confirm that Montréal's economic segregation follows North American trends like the growth of economic disparities (spatial or not) or the fact that the enrichment of central and ex-urban neighbourhoods is compensated by the impoverishment of inner-ring suburbs.

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.     

中国城市的商业郊区化及研究迟缓发展探讨

随着城市人口郊区化、工业郊区化的发展,商业也就不可避免的有向郊区化发展的趋势,中国商业发展状况存在地区不平衡性,大城市商业发展情况较好,一些城市已开始有商业郊区化现象,但是目前商业郊区化的现象还很不明显,相对人口和工业郊区化而言比较迟缓。这与郊区化概念有一定影响外,更主要是因为商业本身的特征(包括发展机制、付租能力、业态多样性等)以及中国的国情等。本文首先回顾了中国商业郊区化的研究,得出商业郊区化的动力主要来自购买力的外移、交通的改善以及郊区地价和租金相对市区便宜等,并在分析商业网点布局的影响因素基础上,探讨城市商业网点布局发展的阶段特征以及阐述商业郊区化为什么在中国发展迟缓的原因。     

长春市人口老龄化时空演变及空间类型研究

构造了一个由数量老龄化、结构老龄化和密度老龄化三个指标所组成的综合老龄化指数（CAI）,并建立了一套人口老龄化空间类型划分方案,运用多尺度空间自相关分析对长春市人口老龄化空间的时空演变及空间类型进行研究。结果表明：①长春市近10年出现了老年人口郊区化的趋势,人口老龄化空间的“中心-边缘”分布格局在10年内没有发生显著改变,但空间扩散趋势十分明显,东部和南部近郊区出现了明显的人口老化趋势。②长春市形成了残留老化、集聚老化、自然老化和集聚稀释四种不同的人口老龄化类型区。城市核心区和远郊区形成以非老年人口大量流失为基本特征的残留老化型地区,而近郊区则形成以年轻人口大量涌入为特征的集聚稀释型地区,人口老龄化空间整体上呈现出一种城市中心区和远郊区的老化程度高于近郊区的夹层结构。     

郊区化与美国购物城的兴起

零售业集中反映了城市空间结构的变化,是衡量城市发展水平的一个重要指标,值得专门研究.本文通过对美国郊区化和购物城兴起关系的探讨,发现两者有很深的内在联系.在美国已成为郊区居民为主的情况下,购物城仍将存在下去,并保持兴盛局面.这对美国现代社会生活产生了很大的积极影响,但同时它也强化了居住区隔离现象,加深了美国社会两极分化的鸿沟.

Restructuring of Beijing's Social Space

Four China-, U.S.-, and UK-based senior specialists on the urban geography of Beijing team up to present the results of their investigation of the change in the city's social landscape on the basis of restricted subdistrict-level data covering the period from 1982 to 2000. Adopting a factor ecology approach, the authors seek to identify the extent to which factors that shape urban social landscapes in Western countries have played a role in Beijing during a period of economic transition (e.g., from administrative toward market allocation of housing). Similarly, they investigate the relative strength of processes of social differentiation vis-à-vis mixing accruing from the restructuring of Beijing's physical space (e.g., housing cost differentiation and accelerated in-migration that lead to the emergence of concentrated areas inhabited by migrants and/or minorities, and of relatively low density suburbs) revealed by the 2000 Census. The paper includes a section on developments since 2000, citing data (through 2006) on population, scarcity of affordable housing, traffic congestion, and industrial and residential relocation, relating in part to the forthcoming Olympic Games in 2008.

A PATH ANALYTIC EXPLORATION OF INCOME CLUSTERING AND LOCAL INEQUALITY

This article explores relationships among income status, economic resources, service needs, and taxing policies for municipalities and schools in 39 metropolitan suburbs of the Milwaukee SMSA. The results indicate some modest support for those who are concerned about the impact of class and income clustering, as well as government fragmentation, on inequalities regarding local tax policy. Use of path analysis to explore some of the possible alternative linkages that account for patterns of fiscal inequality among suburban municipalities shows that fiscal disparities resulting from income clustering by jurisdiction is only partially attributable to resourse and need inequities. It might also be that income status, reflecting differing service preferences, operates directly to generate inter municipal fiscal disparities.
