Economic segregation in urban areas is important to scholars and policymakers because it is thought to exacerbate inequality in social outcomes such as education, social capital formation, and employment. A growing body of comparative work examines factors associated with higher levels of urban segregation within different countries. Increasingly, this work examines differences between levels of segregation across the income distribution rather than just one measure of segregation per city. China has high levels of income inequality and has undergone a dynamic process of urbanization in recent decades as it transitions from a centrally planned system to one in which markets allocate goods. Using census data from the 20 largest cities in China, we measure the level of economic segregation and examine its determinants. Chinese cities are highly segregated. Segregation levels tend to be higher in larger and richer cities and more pronounced among renters. There is a stronger link between segregation based on housing type and expenditure than between migrant status and expenditures, which leads us to speculate that the pace, timing, and scale of housing development are the dominant drivers of economic segregation. 相似文献

The volunteered geographic information (VGI) gains increasing popularity with the general public and scientific community. However, the optimism about the VGI has been tempered by two critical issues: inequality in data coverage (social justice) and data quality. It therefore requires a better understanding of the mechanism driving VGI contributions and content quality. With a case of China, this paper demonstrates one potential avenue, examining the associations between VGI coverage/quality and local demographic and socioeconomic characteristics. In particular, VGI data are harvested from the OpenStreetMap for 333 cities in China. VGI coverage is measured by the total volume of different geographic features (point, line and polygon); and VGI quality is described from two aspects: completeness and accuracy. Geographically weighted regression (GWR) shows that both demographic and socioeconomic factors have statistically significant influences on VGI coverage and quality. More specifically, densely populous cities with more young, educated and non-agricultural people enjoy higher VGI coverage and quality. Cities with lower VGI coverage and quality are primarily located in the western and southwestern regions where the ethnic minorities concentrate. High VGI coverage and quality are possibly observed in economically developed cities with high marketization degree. Besides, possibility of high VGI coverage and quality occurs in cities with more labor in scientific research and greater percentage of employers in the tertiary industry. The GWR also demonstrates that the strength and nature of the obtained relationships vary across the 333 cities. The spatial non-stationary relationships may partially answer for the controversial empirical conclusions in earlier case studies at different scales. Quantitative analysis (Gini index, Lorenz curve and Moran's I index) further evidences the great inequality in VGI coverage and quality. It can be safely inferred that the differences in engagement and use of VGI, as a new digital divide, can raise troubling concerns on the social justice implications. 相似文献

This paper investigates the proposition that socioeconomic status explains a significant amount of the residential segregation between Hispanics, non-Hispanic Whites, non-Hispanic Blacks, and non-Hispanic others (mainly Asians) in metropolitan Miami. First, we test to determine if there is significant segregation within each of the four ethnic groups and we find that there is, except for Blacks. Although the index of dissimilarity suggests that there is segregation by socioeconomic status within Miami's Black population, map analysis reveals that this is not the case. Furthermore, we find that socioeconomic status is not an important factor explaining metropolitan Miami's segregation patterns between these four ethnic groups. When it comes to residential segregation, Miami is similar to most other American cities. This is a significant finding because several recent studies have suggested that standard assimilation theory does not apply to Miami, and segregation is one aspect of assimilation. 相似文献

基于2017年流动人口动态监测数据,选取福厦泉城市群,构建融入-隔离对比的指标体系,探讨了流动人口在流入地的主观社会融合及其影响因素。研究发现：① 流动人口在流入地的主观社会融合程度较高,但融入与隔离并存,且以融入为主。② 流动人口主观社会融合受流迁模式、社会网络、生计资本、制度政策和人口特征等因素综合影响：宏观上基本公共服务均等化能显著地增强融入、削弱隔离,淡化了户籍制度造成的融入障碍;中观上在流入地加强社会交往和积极参加组织活动、改善住房和提高收入确实有助于流动人口在流入地增强融入、减弱隔离,但基于流出地方向的土地预期收益、家庭困难及乡土依恋等主客观因素则增强了流动人口在流入地的主观隔离、削弱了主观融入;微观上近距离、长时段和家庭化迁移的流动人口主观融入程度较高,受教育程度的提高有助于流动人口削弱主观隔离,更好地融入流入地。研究认为应促进流动人口客观融合并使其与主观融合相匹配,改变以流动人口融入当前流入地实现市民化的单向思维,统筹考虑流入地与流出地的双向影响,将流动人口市民化工作重心由落户转向基本公共服务的无差别覆盖,实现流动人口从主观“愿意”到客观“能够”的社会融合。 相似文献

It is generally assumed that the segregation of the poor in German cities is increasing as a result of cumulative polarization processes in a capitalist economy. This has led to the assumption that German cities are increasingly becoming similar to American cities. The idea of an "Americanization" specifically includes the development of the inner-city "poverty ghettos" and their adverse implications for urban social development in general, which is the focus of this paper. Empirical findings based on analyses in five major German cities do not support these assumptions. In particular there is evidence that local businesses can function as a stabilizing factor in high-poverty neighborhoods, which counteracts developments that are associated with American "poverty ghettos." These findings indicate that the significance of poverty segregation is overestimated in the debate on urban social development in Germany. Rather, a conceptualization of urban social development needs to integrate the structure and development of both population and local business at the neighborhood level.

宁杭城市多时空尺度居住空间分异与比较 总被引：1，自引：0，他引：1
城市居住分异具有社会群体与住宅空间的社会—空间双重属性,已有研究多关注社会经济属性,采用非空间分异指数开展单个城市和较大尺度的实证分析,较难有效反映中国当前城市内部日趋复杂多变、异质破碎的居住分异景观。基于住宅空间视角,采用多群体分异指数、空间分异曲线、指数分解模型与地理探测器等方法,以南京、杭州为案例城市,从街道、街区与网格3个尺度,分析宁杭2009—2018年居住空间分异及其影响因素。研究表明：空间分异指数因考虑到住宅空间位置和邻域环境,可作为对非空间分异指数的一种改进;南京不同住宅类型空间分异程度高于杭州,主要是由城市空间结构差异造成的;居住空间分异是城市社会空间资源非均衡配置的结果,其中“中心位势”和“教育配套”等因素对城市居住空间分异的影响最为显著;宁杭城市居住空间分异的共性与特性并存,揭示出城市比较研究的可行性与必要性。通过创新性探索,为中国城市居住分异研究提供新视角、新方法和新思维。 相似文献

This paper concentrates on the 1% richest households in the UK in a comparison with the other four large Western European countries: Germany, France, Italy and Spain. In the European context the UK is an outlier of extreme inequality. Individual level tax data has shown this previously, but earlier research did not make comparisons at the household level, or in as much detail as it is possible to show now given new survey findings.In the UK the geographical separation of the 1% from mainstream society increased in recent decades as their incomes levels diverged widely from that of the mainstream. There is now acute socioeconomic polarization in the UK as compared to the other large European states because of the current extent of income and wealth inequalities in the UK. Not so long ago members of the best-off 1% within the UK were far more evenly spread across both the space and society of the UK than they are today.The UK is now the European country most similar to the USA in terms of income inequalities. Along with Sweden it was least like the USA in the 1960s. This paper concludes by considering what might happen (if current trends continue) to standards of living in general, social spatial polarization, fear and mistrust. Growing income inequalities increase wealth inequalities. Some info-graphics aimed at showing the contemporary extent of wealth inequalities in the UK and USA are presented in conclusion and for use in teaching 相似文献

This study uses a mixed methodology to investigate the relationship between agricultural trade and socioeconomic inequality in Mozambique at multiple geographical scales. The quantitative analysis examines all rural regions of the country and a nationally representative sample of rural households, whereas the qualitative analysis focuses primarily on two case study villages. Research findings suggest that social and geographical context greatly influence the relationships between agricultural trade and regional inequality. Trade-related effects on economic inequality—and the social status of traders—vary across Mozambican regions. Results suggest that trade increases inequality in regions where traders have low social status, but reduces inequality in areas where they have high social status. These findings suggest that social and economic factors work together to shape landscapes of inequality. 相似文献

基于全国第六次人口普查数据的广州新移民居住分异研究 总被引：12，自引：4，他引：8
运用第六次全国人口普查数据,分析当前广州新移民的居住空间分异问题,探讨中国大城市新移民居住空间的整体格局、分异程度及其分异机制,并以此实证中国城市社会空间理论。研究表明：广州新移民的空间分布总体上表现出近郊集中和远郊分散的特征,其中省内新移民较多集中在中心区外围,省外新移民集中分散在远郊。广州新移民与本地常住人口的差异指数为0.48,分异指数为0.46,隔离指数为0.56,超过美国亚裔移民分异的平均水平。此外,各区的分异度水平存在较大差异。机制分析表明,历经30多年的市场化进程,制度因素对新移民聚居区的影响减弱,单位因素对新移民聚居无明显影响,市场因素的作用增强。与西方情况类似,人口和家庭因素对新移民聚居有一定影响,其中年龄因素和婚姻状况是影响新移民聚居的重要因素。总体上,市场化下中国城市新移民的社会隔离正不断转化为明显的空间分异问题。为推进社会融合,应尽快采取社会空间重构措施(如社会规划和社区规划)予以应对。 相似文献

In this paper, I revisit the role of Soviet legacy factors in explaining today’s housing inequalities in a midsized post-Soviet city by investigating social, demographic, economic and geographic determinants of perceived housing quality. Building on a sample survey dataset (n = 3,000) that brings together both Soviet legacy effects and more universal influences on housing inequality, it is shown that various aspects of Soviet housing policy can be traced as well-preserved legacies today. The survey was conducted in 2009 in Stakhanov, Ukraine, and the method of analysis is binomial logistic regression. By capturing both the social costs attributed to the post-Soviet transition crisis as well as the underlying legacy factors inherited from the Soviet epoch, the findings suggest that any analysis of housing inequalities or residential segregation in the post-socialist city must come to terms with the impacts of socialist-era economic priorities on the urban social landscape. 相似文献

北京住宅郊区化与就业空间错位 总被引：38，自引：3，他引：35
北京从20 世纪80 年代末开始出现郊区化,其住宅郊区化特点尤为突出。北京市住宅郊区化的驱动力与西方城市的郊区化相比既有相似之处又有明显差异,相似之处是：都是城市化水平不断提高与社会进步的必然结果,以及土地有偿使用制度的实施和城市规划的引导; 不同之处在于北京的住宅郊区化是一种被动的郊区化,居民本身并不想离开市区,但是旧城改造与市区内高昂的房价迫使居民不得不到郊区购房。随着住宅郊区化的大规模发展,北京也出现了居住与就业的空间错位问题,这种空间错位虽然与美国郊区化过程中空间错位有许多不同之处,但在本质上是一致的,都是出现居住与就业的空间分离,造成低收入阶层通勤的时间成本与经济成本增加,导致交通拥挤、社会隔离等社会问题。 相似文献

广州小北路黑人聚居区社会空间分析 总被引：37，自引：6，他引：31
1978 年改革开放带来中国城市的快速转型。近年来, 针对经济转型背景下中国大城市 的社会空间研究很多, 但对在全球化影响下出现的跨国移民族裔聚居区的研究尚不多见。对 广州黑人聚居区展开研究, 以越秀区小北路为例, 探讨其社会空间特征与演进机制。研究采 用微观视角, 针对典型案例进行问卷调查和半结构式访谈。研究表明, 广州黑人聚居区与西 方同类族裔社会区存在诸多差异。小北路黑人聚居区因全球化下新的“自下而上”的跨国经 济联系而生, 因广州城市的商贸文化、宗教历史、贸易网络和地理气候条件而兴, 其跨国移 民多为来自西非地区的族裔散居者/ 漂泊者(Diaspora), 其人口构成异质多元, 且流动性强。 小北路的社会空间机制既包含被动隔离也包含主动聚居, 其经济形态已经开始向“族裔聚居 区经济”(ethnic enclave economy) 发展。 相似文献

Residential segregation in metropolitan areas has been the subject of much research, but this article analyzes patterns of white–black and white–Hispanic segregation in counties across the United States. Our purpose was to understand county variations in this one dimension of inequality. Conceiving of segregation as relative inequality of access to neighborhood resources, we measured segregation in 2000 by the index of dissimilarity (D) calculated by blocks, mapped the index values, and correlated them with census variables. Three filters enabled us to eliminate counties with characteristics that could have corrupted the analyses, leaving us with more than 1,000 counties in each analysis. Both minority groups were less segregated from whites in the West and South and in metropolitan counties. Lower segregation was strongly associated with higher minority socioeconomic status and higher percentages of minorities living in housing built in the 1990s, and Hispanic–white segregation was lower where more Hispanics were U.S.-born or English proficient. The racial threat hypothesis was supported only weakly and inconsistently. Mapping made it possible to identify regional and local patterns of high and low segregation as well as the lower segregation of suburban counties in some large metropolitan areas. 相似文献

Numerous cities in developing regions worldwide are expanding at a tremendous rate. This requires adequate strategies to address the needs of these growing cities with diverse populations. Nonetheless, the development of urban policies is often hampered by the lack of reliable data or insight in the socio-spatial dynamics of this urban expansion. This paper therefore presents ASSURE, a spatially and temporally explicit model that can simulate urban growth and intra-urban social segregation, taking into account alternative policy strategies and expected social dynamics. The model has a flexible structure that allows incorporating specific city conditions that influence residential decision-making and adapting the simulation to the data available. This, in combination with the transparent model structure, makes ASSURE a potentially valuable decision support tool for urban planning. The potential is demonstrated with an example where the urban growth of and social segregation in Kampala (Uganda) is simulated based on (semi-)quantitative and qualitative data for ca. 800 households collected through interviews. The results of the simulations show that depending on the scenario, the spatial segregation and accessibility problems will evolve highly differently. 相似文献

Levels of spatial segregation in Western European cities are persistent over space and time. To demonstrate the degree or appearance of spatial segregation, most studies on urban residential patterns still rely on fixed spatial units, aspatial measures and single scales. However, a spatial or temporal comparison of patterns and levels of segregation based on such units or metrics is not without problems. To that end, this paper takes an explicit geographic approach and considers individualized neighborhoods using EquiPop-software, allowing various scales. Using the k-nearest neighbors for all individuals increases international comparability and facilitates interpretation, so far often hampered in segregation research. This multiscalar, multigroup comparative approach on ethnic urban geographies – using Belgium as a case study – provides an empirical illustration of a valuable method and tool applicable in segregation research, thereby furthering the comprehension of the increasingly diverse urban geographies and building on emerging work in the US, Europe and beyond. 相似文献

In the early part of the twentieth century, South African cities were segregated in accordance with British city planning concepts that embodied the belief that social order can be manipulated through the urban form. This paper surveys the history of South African planning practices to understand the spread of segregation policies and practices. Whereas scholars tend to agree that the apartheid city (post?1948) is a more highly organized and structured version of the colonial city (pre?1910), the literature lacks consensus on the development of the segregated city (1910?1948) within South Africa. How did concepts of segregation circulate and why was it implemented with such consistency? Accordingly, this paper employs concepts of policy mobilities to trace historical configurations in South Africa to international influences. The focus on the circuits of knowledge explains how concepts and designs transplanted from elsewhere helped create the form of South African cities today. Understanding the movement of planning ideas through policy mobilities furthers geographical understandings of historical circulation processes, the role of the local actors, and policy mobilities failure. This history of learning also challenges the assumption that South African cities are unique and in so doing opens the doors for knowledge sharing between postcolonial cities. 相似文献

In 2009, Sweden experienced a wave of urban unrest concentrated in areas with large foreign-born populations. This episode was seen by many as reflecting a trend towards increased ethnically based residential segregation, in line with scholarly literatures that correlate inequality and rising segregation with increases in unrest or rebellion. In this paper, we analyze the empirical connection between ethnic residential segregation and episodes of urban unrest in Sweden. Unrest is measured by the number of car burnings reported to police between 2002 and 2009. We find a positive and statistically significant link between residential segregation and car burnings at the scale of municipalities and metropolitan districts. Unrest/rebellion is also correlated with high proportion of young adults and social welfare assistance. 相似文献

Residential segregation is a dual process of socio-spatial differentiation in residents and spatio-temporal heterogeneity in dwelling.However,most of the existing studies are es-tablished from the single perspective of urban residents based on demographic data,which is difficult to reveal the dynamics and complex spatial reconstruction within and between cities.With the characteristics of both stability and timeliness,the rapidly changing housing market is one of the processes and results of socio-spatial reconfiguration,and it is undoubtedly a better lens to observe residential segregation.This paper adopts methods such as multi-group segregation index,multi-scalar segregation profiles,and decomposition of segregation index,with Nanjing and Hangzhou as case cities,and establishes multi-scalar segregation profiles and comparative models based on three geographical scales of census tract,block and grid,and different residential types.A quantitative study was conducted on the degree and pattern of multi-scalar residential segregation in Nanjing and Hangzhou from 2009 to 2018.The pa-per found that the spatial segregation index is an improvement of the non-spatial segregation index.There are differences between Nanjing and Hangzhou in the evolution process of residential segregation.Nanjing has a higher degree of spatial differentiation as a whole,among which spatial components have a more significant impact. 相似文献

城市流动人口的社会融合是新型城镇化建设的重点任务。针对现有研究在社会融合的空间特征及流入地作用方面的研究不足,本文基于2017年全国流动人口动态监测调查数据,引入空间分析和分层线性模型,揭示了中国地级以上城市流动人口社会融合的空间格局与影响机制。研究发现：① 中国城市流动人口的总体社会融合指数为0.43,存在行为融合（0.71）>心理融合（0.61）>经济融合（0.33）的维度特征。② 流动人口的社会融合存在空间自相关性和集聚性,高水平社会融合区主要分布在东北地区、山东半岛和川渝地区,低水平社会融合区主要分布在东南沿海、关中平原和华北平原地区。在这些地区中,总体上存在人口50万以下的小城市的流动人口社会融合水平高于大城市的基本特征。③ 流入地因素和个体因素共同影响和形塑了流动人口社会融合的水平和空间格局,且流入地的人口规模、住房支出（房价水平）和公共服务等因素对个体因素的影响具有调节作用,包含正向极化、负向极化、正向均化、负向均化等4种调节机制。本文呼吁从流入地—个体因素关联的人地关系视角开展流动人口社会融合研究,重视流入地因素对个体因素的影响,为基于流入地的政策调控来推进新型城镇化建设提供科学依据。 相似文献
