新型城镇化下住房市场的发展

新型城镇化背景下,随着城镇建设的大力推进和城镇人口的进一步增长,我国住房市场的发展稳定仍具有可持续的发展空间。从2013-2022年住房市场发展的预测分析看,今后住房市场在数量上保持规模发展的同时,重点在于质的发展。在宏观调控和新型城镇化发展目标指引下,房地产业必须进一步优化住宅供应结构,科学合理地制定新城开发规划,提高土地利用效率,稳步实现房地产业的转型发展,打造中国住房市场发展的“升级版”。     

Evolution of urban housing stocks: A model applied to Baltimore and Houston

Historical simulations of urban residential growth in Baltimore and Houston based on a model of the growth process which has two distinct components are presented. The vintage component utilizes the growth of income and population, and an assumption that housing is putty-clay, to predict the age distribution of the housing stock in each period. The spatial component of the model determines where this housing construction will take place according to (1) housing is built on vacant land and (2) the pattern of construction obeys the rules of the standard monocentric models. Housing is demolished when economically obsolete. The putty-clay (vintage) aspect of the model produces fairly accurate city-wide vintage distributions, but there is much more mixing of vintages and income (in Baltimore) by location than predicted, even under monocentric assumptions most favorable to mixing.     

Spatial Growth and Redevelopment with Perfect Foresight and Durable Housing

In this paper, I present a theoretical model of the spatial growth of an urban area with durable housing. I combine several assumptions that typically complicate the analysis: (i) housing developers have perfect foresight; (ii) the initial development and many waves of redevelopment are considered in each developer's plan; and (iii) the closed-city assumption is made, so that the time path of population is exogenous and that of consumer utility is endogenous. I still obtain explicit solutions for the spatial pattern of urban growth, and for the timing of the initial residential development and each successive redevelopment at each distance from the urban center. I compare perfect-foresight growth to growth with static expectations, and I examine the comparative statics of both.     

我国普通商品住房供求的影响因素及其稳定性研究

本文利用1997年到2009年全国以及各地区的房地产面板数据,借鉴蛛网模型的相关理论,构建供给与需求的联立方程,选择固定效应IV估计法拟合面板联立方程模型,对普通商品住房供求的影响因素及其稳定性进行了实证研究。结果表明,我国的普通商品住房市场处于不稳定状态,普通商品住房当期及滞后期的价格、城镇人均可支配收入、城镇就业人口、土地购置面积、经济适用房、别墅的供求状况等因素都对普通商品住房的供求变化产生较为显著的影响。     

Residential Building Permits in Urban Counties: 1990–1997

This paper presents simple empirical models of residential building permits for urban counties in the United States for the period 1990–1997. Building permits, as a percentage of the housing stock, are greater the larger are population growth, the proportion of units that are old (built before 1940), and the proportion of units that are new. A higher initial vacancy rate reduces building permits.     

Dynamics of the housing market

This paper deals with the derivation of the rent values of the standing stock of the housing market with a continuous vintage approach, under malleable stock and homogeneous population assumptions, and under dynamic conditions: population and income growth, technological obsolesence, and a continuous upward shift and elasticity change in the supply function. The core of the model is a Volterra nonlinear integral equation of the second kind, and results are shown in relation to existence, uniqueness and stability. Finally, a spatial-dynamic model is specified by a Fredholm-Volterra nonlinear integral equation, framing the analysis of the housing filtering process with the Burgess-Hoyt concept of directional growth in urban development.     

An open-city model with nonmalleable housing

Previous city and housing models are extended to allow for the nonmalleability of housing and two classes of residents. The model, which is framed in the context of a monocentric circular city, assumes an individual housing unit to be defined in terms of attributes (quality and residential density). The quality of a given housing unit can be varied without adjustment costs, but changes in residential density on a particular site require prior demolition of the existing structure on the site. Producers of housing and consumers are assumed to be myopic. By assuming that the city is in short-run equilibrium at each point of time, it is shown that the pattern of land use observed at any stage depends on the past history of the city and the current rates of population growth. The possibilities for filtering of houses from one income group to another are also discussed briefly.     

适应人口数量和结构变动的刚性住房需求研究——以上海市为例

相对于影响住房供给和需求的其他因素,人口因素具有相对稳定型,因此从人口角度来分析住房市场是一个相当理想的视角。上海作为一个生育率超低水平的城市和快速移民的城市,人口年龄结构的变化也表现得尤其剧烈。准确把握上海的人口状况和结构变动,做好城市住房管理工作,维持稳定的住房价格,保证住房市场得到稳定健康发展,同时提高居民的居住福利,有序推动城市化过程,是上海发展面临的突出挑战。分析上海市户籍人口和常住人口不同的刚性住房需求变迁,得到外来常住流动人口的刚性住房需求将成为城市住房需求的主要动力。基于外来人口的特性,未来本市人口住房购买性刚性需求比例将降低,相应的以租赁等形式的刚性住房需求旺盛,且多以低档小户型住房需求为主。同时,外来常住流动人口中集体户人口增加,集体式公寓等住房类型的刚性需求相应增加。     

城市发展与住房意愿支付价格

以城市在岗职工的平均劳动收入水平和反映城市生活质量的各类宜居性指标建立了中国35个主要城市的城市发展与住房需求关系的模型,并以此估计了城市住房意愿支付价格。实证结果表明,城市在岗职工的平均劳动收入水平和以各类宜居性指标反映的城市生活质量可以解释70%左右住房价格的城市间差异。虽然城市劳动收入对住房意愿支付价格的影响仍然很大,但随着社会经济的发展,中国主要城市的生活质量对住房意愿支付价格增长的贡献有逐步增大的趋势。     

城市商品住宅价格水平影响因素研究

商品住宅价格问题是社会关注的焦点问题.以全国35个重点城市1999年-2005年数据为基础,研究城市住宅价格水平的影响因素.研究显示,代表城市经济发展水平和居民收入水平、单位面积土地投入、城市区位和城市环境等侧面的职工平均工资、单位面积固定资产投资、人均铺装道路面积、距海岸线的距离、通过城市的国道数量、建成区绿化覆盖率这6个因素是影响城市住宅价格水平的主要因素.可以预期,当一个城市的这些因素发生相对变化和绝对变化的时候,城市的住宅价格水平必然会发生相应的变化.阳光充足、水资源丰富、交通便捷的近海地区城市的商品住宅价格变动幅度会由于经济发展、人口增加、区住条件进一步优化、投入加大等各种条件的较大变化而高于其他城市.     

北京：人口剧增背景下的房价综合治理

北京市人口呈现爆炸式增长,有观点认为应放任房价上涨以此解决人口问题。本文从分析北京市近年来人口变动情况及北京市房价现状入手,分析“高房价抑制人口增长论”,提出解决人口剧增的根本性办法是加快城乡统筹,从宏观层面予以解决。在北京市人口剧增的背景下,北京房价的调控措施应该包括坚持限购政策、开征房产税、加大保障性住房建设、打击市场上垄断投机、骗购骗租等不良行为。     

Racial prejudice in a search model of the urban housing market

A simple model of buyer search in an urban housing market is employed to demonstrate that if some whites are unwilling to sell housing to blacks competitive equilibria in which blacks pay more for housing than whites are sustainable. The model is also used to consider a number of issues in the literature on housing discrimination. Most important, it is shown that in equilibrium the housing market will be racially segmented under a wide variety of conditions.     

Topographic amenities,building height,and the supply of urban housing

This article develops a housing supply model that treats explicitly the effects of location-specific amenities. The model employs a production function in which housing services are produced not only by structures, but also by access to and views of location-specific amenities. Housing supply is measured by building height. The model is tested with data from the city of Chicago. Access to and view of Lake Michigan are found to have a significant effect on the height of buildings.     

Growth and Distributional Impacts of Urban Housing Supply: An Application of Urban Land Use and a CGE Model For Seoul

This paper assesses economic effects of housing supplies on the urban growth and income distribution of Seoul, using an urban land use and Computable General Equilibrium model of Seoul economy. The simulation shows that the housing development with the conversion of the green or the industrial land uses into the residential land use leads to an increase of the Gross Regional Product by approximately 1% at the worse income inequality. The aggregate welfare effects in terms of Hicksian Compensating Variation range from 1.746 trillion Korean Won to 1.768 trillion Korean Won on a ten-period average, depending on the type of the land conversion.

Dynamics of land-use for a closed city

This paper analyses land-use patterns in a closed only when experiences a discontinuous population change that is anticipated by developers. At each location, developers choose among five development strategies: constructing a building at time zero which is left standing forever, constructing a building at time zero and replacing it at the date τ of the population change, farming the land until τ, with residential development thereafter, and vice-versa, farming the land continuously. By deriving admissable spatial patterns for these five strategies, the analysis is able to characterize the spatial and temporal pattern of land-use in a closed city.     

Residential succession and land-use dynamics in a vintage model of urban housing

This paper adapts the vintage model of urban housing developed in Brueckner (1978) to a two-class city. Computer simulation of the model highlights the differences between static and dynamic urban areas. The contour of building heights is irregular in the dynamic city and spatial mixing of the two income groups occurs.     

中国城镇化进程对房地产价格影响的实证分析

使用城镇化率、流动人口占比、城镇居民人均总收入和房屋竣工面积4个变量指标来反映我国城镇化进程,运用随机效应面板数据模型,对比分析2005—2013年全国、较发达省份和发展中省份的城镇化进程对房地产价格的影响。实证研究表明：城镇化率提高、流动人口占比增加,对房价的影响实际非常有限;城镇居民人均总收入水平的增加才是引起房价上涨的最重要因素;房屋竣工面积的扩大则引起房价的下跌。区域对比研究还发现,由于城镇化进程不同,相比较发达省份,发展中省份的外来务工人员产生了更有效的住房需求。     

A simple urban growth model with durable housing

In the last decade the static theory of residential urban location and land use has been extensively developed. The theory has generated many useful insights, but because it ignores growth and the durability of housing and urban infrastructure there are many urban phenomena it cannot explain. In this paper a simple urban growth model with durable housing, in which all builders have perfect foresight, is presented. The discussion focuses on the qualitative differences between the economics of this model, the static class of models, and a class of dynamic models in which myopic expectations are assumed.
