This article examines linkages between recent domestic out-migration from immigrant gateway metropolitan areas and nonmetropolitan migration gains, based on data of the 1990 census, 1996 Current Population Survey, and population estimates for the 1990–1996 period from the Bureau of Census. Our analysis of these data suggests that there is a mirror image of migration patterns between high immigration metropolitan area losses and nonmetropolitan area gains. This is especially evident in the West with the relationship between Los Angeles and San Francisco areas' losses on the one hand, and the region's nonmetropolitan gains on the other. While pre-elderly and elderly retirees have contributed to these nonmetropolitan gains, much of it is attributable to the destination choices of suburban-like populations—Whites with children, not college educated, and with lower incomes—that have been leaving high immigration metropolitan areas. This new, more dispersed form of “White flight” holds the potential for reinvigorating smaller, nonmetropolitan communities, but creating, as well, new demographic divisions across space. 相似文献

The fluidity of southern African families is related to a long history of internal and external migration. Currently, HIV/AIDS is having a dramatic impact on extended family structures, with the migration of individual members employed as a coping strategy. Children's migration is one aspect of this that is often distinct from that undertaken by other household members. This article is based on qualitative research conducted in Lesotho and Malawi with young migrants and the households that receive them. It examines the processes of fragmentation and re‐formation of households through the movements of children that are taking place in response to HIV/AIDS, and explores the impacts these processes have on young migrants and the households they join. 相似文献

中国五大城市群人口流入的空间模式及变动趋势 总被引：5，自引：1，他引：4
城市群在中国城镇化格局中占有重要地位,也是快速城市化时期的主要人口流入地。本文关注京津冀、长三角、珠三角、长江中游和成渝五大城市群,利用人口普查和流动人口动态监测调查数据,从流入人口分布格局、流动范围和来源地等多维度剖析城市群人口流入的空间模式,并从居留和落户意愿空间差异的视角探讨空间模式的发展趋势及其对流入地和流出地的影响。研究发现,各城市群流入人口向中心城市持续集中,等级和空间分布格局总体稳定;流动范围有所扩大,省内流动增速普遍高于省际;沿海城市群人口吸引范围大但仍服从距离衰减律,不同来源地流入人口的城市群偏好存在差异。在流入地,沿海城市群中心城市面临流动人口管理服务的持续挑战,内陆城市群中心城市和一般城市吸引力并存;在流出地,平等开放的高质量公共服务供给是吸引人口回流的重要途径,少数地区的人口流失可能成为较长期的现象。 相似文献

邻近性对人口再流动目的地选择的影响 总被引：11，自引：4，他引：7
中国人口流动进入总量稳定下的空间调整新阶段,存量流动人口的再流动成为塑造人口和城镇化格局的主体因素。本文从户籍地和前期流入地两个基点出发,综合考虑地理、制度、信息、社会、认知等维度,构建了双重多维邻近性影响人口再流动目的地选择的理论框架,利用全国流动人口动态监测调查数据和嵌套Logit模型开展实证研究。结果表明：双重多维邻近性对人口再流动的空间选择具有显著而稳健的影响。人口再流动时,会选择与自身知识水平更匹配、与户籍地和前期流入地都更近、信息联系都更强的城市,但社会联系仍主要依靠老家。流动人口具有回到户籍所在省（区、市）的主观意愿,但省内城市普遍机会不多、环境欠佳,缺乏吸引力。相对而言,女性对同乡网络的依赖高于男性;新生代流动人口在很多方面继承了老一代的特点,甚至比后者更依赖老家的信息和社会联系;高学历流动人口在流入地的深度社会融入使其能够利用本地化社会资本,再流动的空间选择也与流入地居民更为类似。 相似文献

ABSTRACT. Miami is the primate city in a system of urban settlements that make up a Cuban ethnic archipelago in the United States. The city is also a national magnet, attracting Cuban migrants from metropolitan regions across the archipelago. Four large secondary cores of Cubans outside Florida serve as major “feeders” to the Miami enclave: northern New Jersey, New York City, Los Angeles, and Chicago. Currents of migration to Miami are especially strong among older, foreign-born, and disadvantaged Cubans, an indication of segmented paths in Cuban assimilation. Although concentration in Metropolitan Miami has been the Cuban story over the past three decades, processes of deconcentration now may well be under way. 相似文献

Interstate migration exchanges in the United States are temporally and spatially transitory. Both the early and mid-1980s exhibited significant fluctuations in the origins and destinations of U.S. migrants, while the late 1980s and early 1990s were even more unstable. Regions once favored by interstate movers such as the West and the South, while remaining attractive, showed evidence of declining favor in the early 1990s. Meanwhile, numerous states in the national interior regained their attractiveness, including several that gained net migrants for the first time in decades. California exhibited a major turnaround in its migration, perturbing the entire U.S. migration system. 相似文献

This paper aims to develop a simple technique for defining employment concentrations, suitable for application to any large North American urban area, and to implement it for a major area. Following a review of earlier work, the 1990 distribution patterns of population, resident workers, and jobs in greater Los Angeles are mapped, summarized in tabular form, and compared. After a consideration of alternative approaches, employment concentrations are delineated using census tracts, with the 1990 employment/residence ratio as chief criterion, rather than job density. Of 120 concentrations defined, 11 have more than 100,000 jobs each and 28 have at least 50,000. Downtown Los Angeles, still the region's largest concentration, now is rivaled by the relatively new Irvine. Comparable 1980 data show job growth in most concentrations, although increases Downtown have been modest. The industry profiles of the largest concentrations vary widely, especially as to the significance of manufacturing, which dominates some concentrations but is relatively unimportant in others. The data are inconclusive as to whether jobs in the region became more or less concentrated during the 1980s. The paper also questions two of Garreau's "edge cities" criteria by showing that most such developments in the Los Angeles region are not wholly new and already existed as job concentrations 30 years ago. 相似文献

空气质量对中国人口迁移的影响 总被引：1，自引：0，他引：1
随着中国流动人口群体构成和迁移模式的持续变化,空气质量等舒适性要素逐渐成为塑造人口迁移空间格局的重要因素。基于2000年以来的人口普查和抽样调查数据,本文探讨了空气质量对人口迁移影响的总体特征、变动趋势和作用模式。研究发现,空气质量已逐渐成为影响中国人口迁移格局的重要因素,且主要表现为推力作用。空气质量直接关系到人口迁出决策,污染严重的地区更难留住人;而在迁入地选择过程中,收入水平和就业机会则更为重要,但其影响近年来有所弱化,城市吸引力更加综合多元。此外,研究还验证了教育资源对人口迁移的导向性作用,并从人口迁移的角度发现了城市群作为城镇化主体形态的地位在持续强化。 相似文献

Knowledge-intensive economic resurgence and social restratification are evidently reshaping the intra-urban space of Los Angeles .In particular, the expansion of white-collar employment is inducing marked readjustments in the geography of housing for these workers, and is promoting significant gentrification of inner-city neighborhoods. Existing accounts of gentrification in the United States are briefly adjudged in relation to (a) the recent historical record of urban change and (b) the theory of land redevelopment. A cartographic and statistical analysis of white-collar residential change in Los Angeles County is then undertaken. The analysis points to the evolving spatial structure of pertinent job opportunities together with related land redevelopment dynamics as the dominant factors underlying recent shifts in white-collar residential activity in the County. Further investigation suggests that gentrification trends in Los Angeles represent a special and problematical case of this broad process of white-collar residential change. . 相似文献

人口回流正成为中国人口流动的重要趋势,并将深刻影响中西部及沿海地区的发展前景。本文从地理学的“距离”视角切入,在传统人口迁移理论的基础上,将两个非经济因素的距离维度,即制度距离和文化距离引入人口回流研究,构建了多维距离影响流动人口回流意愿的理论框架,并运用全国层面的流动人口调查数据进行实证分析。结果发现：与理论预测一致,流入地与户籍地间的多维距离对流动人口的回流意愿具有显著的影响。经济距离抑制了流动人口的回流,而地理距离、制度距离和文化距离均对人口回流产生促进作用。在考虑了解释变量可能存在的测量误差后,这一发现依然稳健。此外,多维距离对回流意愿的影响因流动人口个体及所在城市特征的差异而不同。个体异质性方面,随着流动人口年龄的增长和文化水平的提高,经济距离对回流意愿的影响不断增强,而地理距离的影响则逐渐减弱。城市异质性方面,随着城市人口规模的增加,制度距离对回流意愿的促进作用不断减弱;城市经济水平的提高则弱化了地理距离对回流意愿的正向效应。 相似文献

生活方式型移民研究综述 总被引：3，自引：1，他引：2
在经济比较发达以及后现代社会带来个人主体性增强的背景下,以寻找更好的生活方式的迁移——“生活方式型移民”成为一种重要的人口流动类型,并受到西方学者的高度关注。在中国,生活方式型移民开始萌芽,然而研究较少,目前主要集中在对生活方式型旅游企业主移民研究;西方的研究则涉及退休移民、生活方式型企业主移民等多种类型,但尚未形成完整的研究体系,对于生活方式型移民概念界定及其类型划分较为杂乱。为此,本文从现有文献出发,试图对这类移民的研究内容进行介绍、探讨、厘清和评析,首先确定“生活方式型移民”的概念框架,根据生产和消费在时间和空间上的结合状态将生活方式型移民划分为三种类型,并从社会交往、生活状态、旅游行为和自我认知等方面综述其迁移后的行为表现及由此产生的影响,希望借此促进中国学者对生活方式型移民的关注。 相似文献

中国省际人口迁移的多边效应机制分析 总被引：12，自引：6，他引：6
区际人口迁移不仅与迁出地和目的地的要素特征以及距离有关,而且还受到周边迁移流的影响.基于网络自相关理论,利用"六普"省际人口迁移数据和相关统计资料,在重力模型的基础上考虑迁移流之间可能存在的几种空间依赖形式,构建中国省际迁移流的空间OD模型,初步揭示区域经济社会等因素及其空间溢出效应对省际人口迁移的影响,并就区域要素变化对整个省际人口迁移系统产生的"连锁反应"进行了模拟.结果表明:① 中国省际迁移流之间存在显著的网络自相关效应.目的地和迁出地的自相关效应皆为正,导致迁入和迁出流的空间效仿行为;迁出地和目的地周边则出现负的自相关效应,导致迁移流的空间竞争行为;② 区域经济社会等因素通过网络空间关系对周边地区产生的多边溢出效应导致迁移流在空间上集聚.其中,距离衰减效应位居各要素之首,其溢出效应进一步加剧距离的摩擦作用;对目的地而言,区域工资水平和迁移存量超过GDP的影响并产生正的溢出效应,促进周边地区吸引更多的外来人口;对迁出地而言,人口规模和迁移存量产生正的溢出效应,推动周边地区人口外迁;③ 区域要素变化潜在地对整个省际人口迁移系统产生一系列"连锁反应",震荡中心及其周边区域的迁移流波动较大.江苏省GDP增长5%的模拟结果表明,江苏迁往全国其他省份的人口数量都有不同程度地减少,而其他省份入迁人口均有所增加.相对而言,江苏周边省份的迁入或迁出流受到的波动较大,偏远省份波及较小,这是传统的重力模型所无法解释的. 相似文献

This article examines the nature and timing of U.S. foreign direct investment (FDI) in the London legal market. Evidence from a survey of thirty–eight U.S. subsidiaries suggests that FDI has taken place primarily to serve U.S. clients located within the United Kingdom. The evidence also suggests that early investors (pre–1990) belong to a core group of multinational companies with headquarters located in first–tier U.S. cities (New York, Chicago, Los Angeles). Later investors more typically hail from smaller cities. The evidence reveals a number of important differences between early versus late investors. Specifically, subsidiaries that were established prior to 1990 are more likely to enjoy local decision–making autonomy than are their counterparts that entered the London market more recently. The article concludes with a brief discussion of the implications of the survey findings for future research on FDI in professional services. 相似文献

新型城镇化背景下流动特征与农民工回流意愿的关系 总被引：1，自引：0，他引：1
使用2016年中国流动人口动态监测调查数据,借助描述性分析和多分类Logistic回归模型分析方法,探讨新型城镇化背景下农民工回流意愿的现状与特点、流动特征与回流意愿的关系。研究发现,农民工的回流意愿很弱,有回流意愿并打算近期回流的农民工比例较低,回流地域以原居地为主、户籍地的乡镇和区县政府所在地为辅。模型结果显示,流动特征显著影响农民工的回流意愿：跨省流动者“打算回流”的概率大于省内流动者;流动时间短和非举家流动者“打算回流”“近期回流”“回原居地”的概率分别大于流动时间长和举家流动者;有留守子女者“打算回流”“近期回流”的概率大于没有留守子女者。最后,建议政府实施以“异地市民化”为主、“回流式市民化”为辅的市民化策略;继续深化制度改革,为农民工流动扫清制度壁垒和提供均等化公共服务;促进中西部和东北部地区的经济社会发展,出台鼓励农民工回乡创业和就业的优惠政策等方式来推进以农民工市民化为重点的新型城镇化发展。 相似文献

This paper uses the U.S. 1990 Public Use Micro Sample to characterize the 1985-1990 primary, return, and onward interstate migration patterns for blacks and whites. The classification of these three types of migration is based on the state of birth and state of residence at the start and end of the census interval. Major migration streams, migration rates, and net migration are evaluated for each migrant type and compared for blacks and whites. Overall, the migration patterns of blacks resemble those of whites, with an attraction to the South and the Southwest and movement out of the Northeast and the Midwest. Some differences were observed, however, between the two races. Return migration rates were somewhat higher for black migrants as compared with whites, and onward migration rates were lower. Black primary out-migrants represented a larger proportion of the total flows from the southern states as compared with white out-migrant flows, and they represented a larger share of the out-migrants from the rust belt states. The major migration streams also had different regional and national patterns by race and migrant type. 相似文献

The household registration (hukou) system in China was studied using China's 1990 census 1% microdata and interprovincial migration studies. In doing this, the socioeconomic characteristics and geographical patterns of long-distance hukou and non-hukou migratory flows were compared before developing a framework of dual migration circuits. The framework uses a statistical model to evaluate migration rates in relation to both origin and destination variables. It was found that these two types of migrants shared some general demographic characteristics, but displayed substantial socioeconomic differences. The hukou migrants that tended to originate in urban areas had an extremely high share of college-educated people and were employed in higher skilled jobs, while non-hukou migrants were mostly from rural areas with much lower educational attainment. Hukou labor migrants tended to move through government and formal channels, while non-hukou migrants relied on their own, often informal, source of jobs. Furthermore, a difference as to the migration mechanisms between hukou and non-hukou migrants was noted. Non-hukou migration rate were tied positively to the migration stock, a process consistent with a networked migration hypothesis, while hukou migration rates were not. The rural labor migrants moved away from provinces of high population pressure to those with more favorable land/labor ratios, in line with neoclassical predictions. Hukou migration moved in the opposite direction, reflecting a different set of factors at work. The analysis indicates that the hukou system remained a relatively powerful institution in structuring migration in the 1980s. 相似文献

By the mid‐twentieth century the population and economic resources in many developing economies had become concentrated in the capital city. Planned industrial cities became an important mechanism to encourage more balanced urban systems as well as development in peripheralized regions. Venezuela boasts one of the most impressive planned industrial cities, Ciudad Guayana, constructed in 1959 in the resource rich but inaccessible Bolivar state in the southeast. This paper summarizes the lifetime migration to and from Bolivar state for the years 1950, 1971 and 2001. Whereas the majority of lifetime migrants originated from the neighbouring northeast region in 1950 and 1971, by 2001 more migrants arrived from the capital region. For lifetime outmigrants, the destination states became more diverse and less focused on the capital region. Gender ratios of lifetime migrants to and from Bolivar became more equitable as women became more prominent in migration flows. The level of urban primacy in Venezuela declined substantially after 1971 as the country became more internally integrated, although this more equitable distribution of the country's population may not have been solely a result of the creation of the growth pole, but a result of wider economic development. 相似文献
