大都市边缘区农村居民对宅基地退出和定居的思考——以南京市江宁区为例

中国的快速城镇化推动了乡村发展转型与空间重构,农村居民对于土地退出、定居的想法正发生着变化。基于2014 年在南京市江宁区的问卷及访谈调查,本文探索了发达地区大都市边缘区中农村居民针对宅基地退出和未来定居的意愿。通过运用访谈资料和回归模型,本文发现村庄属性、一些个人主客观因子都影响着农村居民对于土地退出和未来定居的决策。本文还发现,相当多的农村居民倾向于在邻近小城镇定居,对宅基地退出普遍持负面态度。随着宅基地财产功能的提升、城乡一体化进程推进等方面的变化,关于宅基地流转制度的改革势在必行。     

Geographies of adult multigenerational family households in metropolitan Sydney

This paper investigates spatial trends of multigenerational adult families in metropolitan Sydney. Australia's immigrant gateway city, Sydney has high housing costs and infrastructure pressures, and planning policies support higher residential densities. In this context, the accommodation of persons living in multigenerational families is examined, by major region of origin, their geographies in Sydney, and by housing costs and constraints. Results highlight that cultural origins were influential in multigenerational household formations, and such formation is higher in areas of first and second ethnic community formation areas. Multigenerational living is also more common in middle ring and outer areas of cheaper housing. Implications are drawn for more nuanced housing policies in Sydney and comparable cities, given that detached and semi‐detached houses were favoured by these households, whereas two‐fifths of new housing constructed in Sydney in 2011 consists of two or less bedroom apartments.

ECONOMETRIC ANALYSIS OF HOUSING TRAIT PRICES IN A THIRD WORLD CITY*

ABSTRACT. A first step in the process of economic analysis of housing markets in Third World cities is the econometric analysis of housing trait prices. The information on market price of housing is basic to the derivation/estimation of other market parameters such as housing demand and supply elasticities. In addition, housing trait prices constitute invaluable inputs into the analysis of effects of government housing programs. This paper presents estimates of housing trait prices in a Third World city housing market, the city of Jos in Nigeria. Nonlinear stochastic specification of a policy constrained hedonic price function is presented as an unbiased estimator of housing trait prices. The Box-Cox statistical procedure was employed in the paper to obtain hedonic regression coefficients which are the parameters needed to compute the average prices evaluated both at the mean of each trait and at their margins. The potential uses of housing trait prices for policy analysis are discussed briefly.     

Population Suburbanization in American Metropolitan Areas, 1940–1970

Using census tract data, this paper shows that massive changes have occurred in density patterns of American metropolitan areas since 1950. Suburbanization of population has involved both large-scale decongestion of central parts of metropolitan areas and also large-scale outward deconcentration. Many metropolitan areas no longer have clearly distinguishable density patterns in their central and peripheral parts. At the present time, patterns of population distribution across metropolitan areas are becoming increasingly similar. Furthermore, current suburbanization patterns by census tract do not relate strongly to suburbanization patterns as measured by growth rates of crude central city and suburban rings in metropolitan areas. Finally, the paper shows that “density craters” in the center of many metropolitan areas may become more pronounced, although they may not extend outward.     

住房制度改革对中国城市居住分异的影响

住房制度改革是中国城市居住分异的重要影响因素。住房制度改革后,城市居民可根据自身社会经济特征和消费偏好,选择居住区位和住房与邻里质量,住房选择行为相对自由化。商品房的开发在住房制度改革后得到鼓励,房产商在政府宏观调控指引下,自主选择投资区位,建设不同层次的住房和邻里,以满足不同层次居民的居住需求。不同类型企业、不同工龄的职工在享受房改房的机会明显不同,造成享受者和未享受者住房条件的差异,从而形成居住分异。公共部门的干预使得住房类型构成多样化,出现了经济适用房、房改房和廉租房等资助房,与商品房并存;种种约束条件使得社会群体在不同类型住房中分布并不均衡,形成居住分异。     

COMPENSATION FOR COMMUTES IN THE LAND AND LABOR MARKETS: SOME EVIDENCE FROM THE TOKYO METROPOLITAN AREA*

ABSTRACT. Recent research suggests that in nonmonocentric cities compensation for commutes takes the form of both lower housing prices and higher wages. This paper develops a random utility model that predicts the probability of an actor choosing to commute between each residence and job in a metropolitan area conditional on the observed location of housing units and job sites. The model allows commuting time, origin-specific amenities, land prices, destination-specific amenities and wages to influence actors' choices. We estimate the model using maximum likelihood and generalized least squares techniques and data on commuting between each of 38 origin and 15 destination jurisdictions in the Tokyo metropolitan area. The empirical results show that, all else equal, a one percent increase in commuting time reduces the probability that a route (origin-destination combination) will be chosen by almost five percent. Origin-specific amenities are not completely capitalized into land prices and destination-specific amenities are not completely capitalized into wages. Desirable residential amenities include school quality and a low ratio of day to night population. Desirable workplace amenities include a large share of white collar jobs and a high density of employment.     

OPTIMAL HOUSING COST ESTIMATES FOR 177 U.S. METROPOLITAN AREAS

ABSTRACT This research tests the ability of six metropolitan‐level measures of housing costs to predict a benchmark housing cost measure based on Aten's area price level index. The first four measures are calculated with U.S. Census Data, the fifth is based on HUD Fair Market Rents, and the sixth is the housing portion of the ACCRA Index. In 25 large metropolitan areas, the fourth measure predicts 86 percent of the variation in the benchmark index in 1990 and 85 percent in 2000. The fifth measure performs nearly as well. The paper concludes both are promising measures of living costs.     

Temporal and Spatial Dynamics of the New Residential Areas around Tallinn

New housing construction is the most visible manifestation of the rapid suburbanization process taking place in the former centrally planned countries of Central Eastern Europe. This paper analyses residential housing construction around Tallinn, the capital city of Estonia, in the period 1991–2005. Our data comes from the New Residential Area Survey that was carried out in 2006. The main results of the study reveal that housing construction was modest in the 1990s, but grew rapidly in the 2000s. In comparison with the Soviet period, private interest led new housing construction to take place in areas closer to Tallinn that were earlier reserved for other functions; that is former agricultural and coastal (often military) areas. Instead of the sprawl of detached housing further away from the capital city seen over time, we find increasing in-fills and multifamily housing construction in the 2000s around Tallinn. This leads to changes both in the internal structure (small but merging settlements close to Tallinn are different from the Soviet time compact settlements located all over the rural areas) and functioning (increase in daily commuting) of the metropolitan area. We argue that the transition period ends in the housing market when a new and better balance between public and private interests emerges in Estonia like in Western Europe.     

Informal housing,spatial structure,and city compactness

This paper develops a monocentric city model with a formal and an informal sector in the housing industry. While formal developers build houses renting land from landowners, informal developers use land for free. However, informal developers must incur defensive expenditures to avoid government intervention. In equilibrium, at any distance of the central business district (CBD), informal developers use land until the value of the marginal productivity of land equals the defensive expenditures per unit of land. The model shows the land allocated to produce short informal (tall formal) buildings increases (decreases) with distance to the CBD. Thus, the model introduces a new source of spatial variation of building height. The model also shows that a higher level of informal housing increases the spatial size of a city and reduces the height of its buildings.     

HOUSING CONSUMPTION DECLINES WITH INCOME IN THE OPEN‐CITY MODEL: THEORY AND EMPIRICAL EVIDENCE

This paper demonstrates that the standard urban model (SUM) has important, previously unknown, and rather counterintuitive predictions about the determinants of housing consumption in cities. For example, the SUM predicts that, as higher wages in the central business district prompt city growth, the housing space per household falls, that is, rising income is associated with falling housing consumption. Empirical testing using a specially constructed panel data set of U.S. cities, confirms this prediction. When city size, income, and housing price rise, housing space per household falls.     

Environmental Quality and User Satisfaction in Mass Housing Areas: The Case of Istanbul

In a residence environment, housing and housing groups constitute a fundamental life space to meet the needs of the residents, to satisfy them, and to maintain the overall health of individuals and public. Various needs that appear due to the problems caused by housing and residence environment situated in a physical, psychological and socio-cultural environment together with their surroundings affect resident satisfaction and attitude, while directing the overall individual/family and public health, happiness and welfare. Most researchers argue about and try to determine the residents' needs related to their expectations of and satisfaction in housing and residence environment, within the framework of basic needs of human beings. In this study, in order to assess the factors that improve housing and environmental quality satisfaction, the concepts of housing and its environment, and the subject of housing and environmental quality satisfaction have been investigated; the conceptual model of housing and environmental quality satisfaction has been developed, which takes up the subject of user satisfaction in housing and environment quality as a whole; and the factors to increase the level of satisfaction in housing and environmental quality have been specified. A sum of 400 questionnaire inquiries has been made in planned mass housing areas in the Istanbul Metropolitan Area. Applying factor analysis to the data that have been gathered as a result of questionnaire inquiries, the following factors have been determined according to their order of importance to increase the level of user satisfaction in housing and environmental quality. The findings of this study show that, the elements influencing these factor groups include accessibility to various function areas in the inhabited housing area, environmental features of the housing, satisfaction in the various facilities in the inhabited environment, environmental security, neighbour relationships, and the appearance of the housing environment. A logistic regression model has been made to assess whether there are any differences among the factors influencing housing and environmental quality satisfaction for mass housing users on location choice (central districts and peripheral districts) at the metropolitan level.     

Drink Driving: Offenders and Penalties in Metropolitan Hobart

Conviction rates for drink driving charges vary markedly between suburbs in metropolitan Hobart. Particularly high rates occur in public housing and inner city areas. Low rates typify the more affluent suburbs. The pattern may reflect a complex interplay between police implementation of random breath testing, constraints imposed by the physical structure of the city, and varying attitudes towards the law. Court penalties imposed on drink drivers also vary markedly between suburbs. Recidivism probably provides much of an explanation; the role of other factors cannot yet be assessed.     

A Mathematical Model of the Density Distribution of Moscow's Population

A student research project at Moscow University tests Colin Clark's formula for the distribution of the density of a single-center city by applying it to population data of Moscow for 1963, 1964, and 1965. The students obtain repression lines and equations for the population density of Moscow and draw the density field by means of isolines. The results suggest population movement from the central district to outlying areas where intensive housing construction is under way.

Central Cities as Engines of Metropolitan Area Growth*

The paper analyzes the role of central cities as engines of economic growth in their metropolitan area. We wonder if there are increasing returns to central city growth at the metropolitan level arising from the positive externalities associated with the unique features of central cities. To answer this question we analyze the causality between the economic growth of Spanish central cities and the growth of the other jurisdictions belonging to their metropolitan area (i.e., the suburbs). The analysis uses population and economic activity data for a sample of 28 Spanish metropolitan areas during 35 years. We use a Vector Error Correction Model (VECM) framework to estimate long‐run equilibrium relationships between the growth of central cities and their suburbs. The combination of panel data and a VECM is an innovative approach that is still being developed in econometrics. The results suggest that central city growth has a long‐run positive effect on the growth of the suburbs. We also inquire as to whether or not this positive effect depends on the size of the central city. The results suggest that the effect is much higher in the case of the largest cities, but that it is also important in the case of the smaller ones.

Concentrated Urban Poverty: The Case of Izmir Inner Area,Turkey

In Turkey, poverty has been a main subject of debates since 1960s. It used to be a serious problem for both rural areas and the big cities that gained migration. In Turkey and world-wide since the 1980s, however, there have been more research interests in the concentrated urban poverty, especially along with the increase in levels of impoverishment around the world. With the help of a case study in Izmir (Turkey), this paper aims to examine the process of concentrated urban poverty from different points of view in the literature. This is a case study developed at the peripheries of the traditional city centre—or inner areas—of the city of Izmir, Turkey. The paper, first, discusses the parameters of concentrated poverty according to the literature. Then it introduces the study findings of the author, which point out the macro-scale, micro-scale and ecological dynamics that are important in the development of concentrated urban poverty. The macro-scale dynamics suggest that poverty in inner areas of the city are related to the unbalanced development trends within the country, such as the overgrowth of metropolitan cities, economic restructuring processes, migration trends and the development of informal economy. The ecological dynamics address to the housing and job location preferences and invasion-succession processes in the city, which emphasize that socio-economic characteristics of inner areas of the city are different from those of other city parts. Micro-scale dynamics are related to poors' ability of developing solidarity relations among themselves, which is also related to the spatial characteristics of inner areas of the city, according to this study's findings.
