流动人口居留稳定性的群体分异与空间格局   总被引:1,自引:0,他引:1  
利用2015年全国1%人口抽样调查数据,本文分析了流动人口居留稳定性的总体特征、群体分异和空间差异性,并对流动人口居留稳定性的影响因素进行了探讨。结果表明:①我国跨市流动人口在当前城市的平均居住时间约为5年,新生代流动人口的居留稳定性与老一代并没有显著差异,从事工业行业的流动人口居留稳定性明显低于各类服务业从业者;②省内流动人口的居留稳定性低于省际流动人口,且有更大的可能离开当前城市,转向省际流动;③城市流动人口的规模和居留稳定性在空间格局和影响因素方面均存在明显差异,虽然收入水平和就业机会依然是吸引流动人口的主要因素,但公共服务、住房市场和环境等城市宜居性因素对提高流动人口的居留稳定性更为重要。  相似文献

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.  相似文献

Northern Chile, part of the south central Andes, consists of two main ecological subareas: extreme northern Chile, including the western valleys, and the Atacama Desert and oases. Different ecological conditions obtain in each subarea: puna, altiplano, and precordillera in the highlands; valleys, the desert, and oases in the intermediate zone; and coastal environments along the Pacific shores. In prehistoric times, all these environments were very interconnected. There are three different cultural traditions in the local prehistory: the early hunting and gathering tradition (10,000–4000 B.P.), the Chinchorro Tradition (7500–2500 B.P.), and the Altiplano or Andean Tradition (3000–0 B.P.). This proposed sequence is described, with emphasis on the early Chinchorro adaptations, including the important patterns of mummification, and its possible relation to tropical forest groups of the Amazon basin; and the Pre-Tiwanaku and later Tiwanaku and Inca developments, in relation to the circum-Titicaca region. The data presented in the paper are further developed to explore ideas and hypotheses for future research.  相似文献

中国户籍制度的现代化转型是从清末民初开始起步的,当时的执政者把推行现代户籍制度作为实现宪政的一项基本制度条件。国民党执政时期,国民政府把户政建设视为"庶政之母",列为"训政时期"基础性的国家政治建设,即使八年抗战时期也没有停顿,从而构建了一套比较完备的现代户籍法律体系。但是,这个制度建设的步伐在实践中受阻于战乱,到1949年以后则完全中断了。新中国的户籍制度建设走上了另一条路线——计划经济的人口统制管理方式,在各种因素的影响下,最终形成了城乡二元户籍制度。  相似文献

西部地区农户经济的空间差异及其发展对策   总被引:2,自引:0,他引:2  
范建刚 《人文地理》2002,17(3):63-65
西部不同地带生态条件的优劣差异决定了西部地区农户经济的空间差异,劣等、中等、优等三类生态条件相应地发育出贫困、温饱、富裕三类群落的农户经济。西部各类农户经济的发展有着不同困难,贫困群落农户脱贫面临人口压力大与生态环境脆弱矛盾突出,及农户人均财政负担重,财政支农能力差的困难,已得温饱的农户面临收入与文化素质低、可带动农户从事产业化经营的企业少的困难,富裕农户面临生产要素流失严重,制度创新滞后的困难。由政府主导,以多种手段、方式带动贫困农户脱贫致富;扶持建立农业合作经营组织,促进已得温饱农户发展农业产业化经营;以制度创新推动富裕农户经济的进一步发展,是应采取的针对性对策。  相似文献

Millions of people in India are born with scars that will last a lifetime. These are scars of social rather than physical blemish and they reduce the capacity of such persons to function in life, free of prejudice and untainted by stigma. The source of these wounds is the practice of ‘untouchability’, meaning that any physical contact with them is avoided because they are considered ‘unclean’. This article studies the nature of households in India that admit to ‘practising untouchability’ — in the sense of avoiding contact with persons they regard as unclean — and contrasts such households with those that claim to be not ‘practising untouchability’. Such a contrast is possible because the data used, which are from the Indian Human Development Survey, associate with each household a wealth of economic, social and demographic data. Consequently, it is possible to estimate the likelihood of a household practising untouchability, conditional upon the values pertaining to it of a number of relevant factors. These include its social group, its main source of income, the highest educational level of its members, its urban or rural location and its region of residence. The central finding of the analysis is that the practice of untouchability is determined more by the region in which a household is located than by the caste to which it belongs.  相似文献

The concept of the Daily Urban System (DUS) has gained relevance over the past decades as the entity to examine and explain the functionality of the urban landscape. Daily Urban Systems are usually defined and measured by the strength of commuter or shopper flows between the nodes of the system. It is important to realize that these Daily Urban Systems are the accumulated pattern of individuals making frequent, recurring trips to other localities than their own. Understanding the microeconomic decisions behind these spatial interactions will help in assessing the functional and spatial structure of DUS. In this paper is explored how, based on Dutch empirical data, the individual household’s spatial interactions shape the daily urban system and how the destination of these interactions correlates with personal and spatial variables and motives for interaction. The results show that the occurrence of non-local spatial interactions can be explained by the size-based Christallerian hierarchy of the localities of residence, but that it is the regional population – or market potential – that explains and moderates the sorting of households and the intensity and direction of their spatial interactions in the DUS, matching agglomeration theory.  相似文献

This article shows that, in the study of immigrant integration policy in the U.S. states, it is critical to report data and coding decisions for individual laws. This analysis uses an updated and public database of law‐level decisions, which includes 2,703 legislative actions recorded by the National Conference of State Legislatures from 2005 to 2016. These data are used to estimate models of aggregate state policy activity in a variety of ways: as a single continuum of policy balance versus separate models of welcoming and hostile, lumping all policy subareas together versus analyzing a specific subarea, and lumping all years together in one cross section versus panel analysis. The results in these models differ enough to indicate that reporting codes for individual‐level laws is absolutely essential so that each researcher easily can construct the measure that fits his or her theoretical framework best.  相似文献

A formula for migration rate, proposed by Bogue, Shryock and Hoermann (1957), is modified to yield a simple coefficient of migration intensity for the analysis of the intensity of interregional streams of migration among the 72 oblasts, krays and autonomous republics of the RSFSR, the principal republic of the Soviet Union. The coefficient, which eliminates the impact of the populations of both region of origin and region of destination on the value of the coefficient, is obtained by dividing the shares of all regions of origin in the migration to each region of destination by the shares of the regions of destination in the total population of all regions. The 5112 coefficients of migration intensity are arrayed in a table and subjected to some preliminary analysis of migration patterns. The basic pattern is determined by 171 coefficients with values of 5 or higher, accounting for 3.4 percent of the total number of coefficients.  相似文献

Two regional characteristics—contiguity (connectivity) and compactness—are described mathematically. An integer programming model is constructed to allocate a system of points optimally (in terms of the compactness criterion) to subgroups whose number is not given beforehand. The conditions that each element of the regional breakdown must satisfy are given in the form of linear constraints of the regional population structure.  相似文献

"The current work extends the modeling of the household migration decision to take into account location-specific influences and relates these to regional wage differentials. This allows for more complete analysis of real wage gains or losses associated with migration and inferences regarding the nature of equilibrium or disequilibrium wage differentials between regions." Data are from the Michigan Panel Study of Income Dynamics for the period 1976-1978. "The results indicate systematic and often substantial influences of household location on the nominal wage and on both job and residence mobility. Based on these findings, comparisons of wage growth patterns are made for those changing jobs and region of residence status. Although compared to other households the wage growth of these migrants is on average lower before migration and higher after migration, the analysis provides no support for arguments that nominal regional wage differentials reflect systematic ordering of real wage differentials. This finding suggests that real wage gains are closely tied to the interregional migration decision but are not related to regional nominal wage differentials in a simple fashion."  相似文献

A simplified middle atmosphere general circulation model is used to investigate the nonlinear behavior of the thermal diurnal tidal waves. In the model, only a westward moving diurnal tide generated by heating with zonal wavenumber 1 is considered. The tidal wave propagation is simulated by a full nonlinear calculation with a convective adjustment scheme and a Richardson number dependent vertical eddy diffusion.The numerical results show that the growth of the diurnal tide due to the density stratification is effectively suppressed and a relatively constant amplitude distribution with height is realized by the convective adjustment in the lower thermosphere. It is also shown that mean zonal winds and mean meridional circulations are induced by the diurnal tidal waves in the region where the tidal waves are breaking by convective instability, in accordance with the wave-mean flow interaction theorem.  相似文献

This study attempts to evaluate the factors affecting adult mortality with special emphasis on the lifestyle factors using the 1998–1999 National Family Health Survey (NFHS). The sample size, N, in this analysis is 330,267. It includes those aged 15–59 of which 2.6 per cent died during adulthood. In the Poisson regression model, the independent variables used are age, sex, place of residence, lifestyle factors of other members of the family, standard of living, literacy composition, caste, religion, mass media exposure, household type, fuel for cooking and region of residence. This analysis has been adjusted for the clustering of deaths at the family level. The findings suggest that there is a strong positive relationship between lifestyle factors and premature mortality, even after controlling for other background characteristics of the deceased person. Further, age, standard of living index (SLI), literacy composition, religion, household type and region of residence are some important determinants of adult mortality in India.  相似文献

The People's Republic of China conducted its fifth population census in November 2000. This paper draws from that census and recent data to examine national and regional demographic changes in China over the past two decades. Nationally, the impact of fertility decline on rates of population growth, age composition, and household size is investigated. Regional population trends include the rising population share of the eastern region as a result of population growth due to migration and in response to the widening economic gap between coastal and interior China. Demographic differentials between the eastern region and the rest of China (i.e., in proportion of working-age population, household size, sex ratio, and levels of urbanization and educational attainment) suggest that migration is playing an increasingly important role in shaping regional population distribution and that the acceleration of uneven regional development poses a major challenge to policy makers.
