Understanding housing submarket structure is of crucial importance to both public and private agencies. It can also help current and future homeowners make informed decisions on their residential choices. Current research on submarket focuses on comparative analyses of different classification techniques. Few studies, however, have examined the function of spatial contiguity on housing submarket classification. To address this issue, this paper developed a spatially constrained data-driven submarket classification methodology to obtain spatially integrated housing market segments. Specifically, a data-driven model based on principal component analysis and cluster analysis was developed for delineating housing submarkets. Within the model, a number of location attributes were used for principal component analysis, and the geographic locations of houses were also incorporated in the cluster analysis. The performance of this method was compared with other unconstrained data-driven techniques and a priori classifications using three measurements: substitutability, spatial integrity, and similarity. Results indicate that spatially contiguous submarkets can be obtained without compromising housing hedonic model accuracy and attribute homogeneity.  相似文献

研究轨道交通对沿线住宅价格的影响有助于将轨道交通带来的外部效益转化为内部收益,对城市地铁的建设和运营具有重要意义。在真实城市空间中,由于空间异质性的存在,轨道交通对不同区域的影响并非都是相同的,因而需要划定分市场进行研究。本研究以深圳龙岗线郊区段为对象,首先运用Moran'I 指数证实了空间自相关效应的存在,并构造变量将空间自相关效应纳入模型进行控制,结合其他变量构建了4 个Hedonic 模型,然后通过Chow Statistics 检验划定远郊段和近郊段2 个分市场,最后运用最优的Hedonic 模型对轨道交通影响住宅价格的分市场进行研究并解释其形成原因。研究结果表明:① 轨道交通在近郊段对沿线住宅价格具有正向影响;② 轨道交通对沿线住宅价格影响存在分市场效应,不同分市场中轨道交通对沿线住宅价格的影响程度差异较大,龙岗线近郊段对沿线住宅价格具有正向影响,远郊段对沿线住宅价格具有负向影响;③ 可以通过Chow Statistics检验来划定分市场,龙岗线近郊段和远郊段的分界点为“六约—丹竹头”,近郊段分市场的空间范围可能与城市的平均通勤时间有关;④分市场的形成原因是空间异质性,龙岗线郊区段的分市场是由两个区域中心的空间分布差异所导致。  相似文献

This study aims to investigate the spatial and temporal dynamics of housing prices associated with the 2007 U.S. housing-market bubble in Midwest Pinellas County, Florida. Two methods were used to examine the spatial and temporal dynamic of price levels: housing characteristic influence estimation and a hedonic modeling approach. Two consistent spatial patterns emerged in the estimated coefficients associated with various housing characteristics, with definitive changes occurring at 600 m and 2200 m from the coast. These changes suggested the existence of three geographical submarkets: a coastal, an intermediate or transitional, and an inland submarket. Three temporal stages were observed from the coefficient trends associated with various housing characteristics: 2002–2005 (bubble-growing), 2006–2008 (bubble-burst), and 2009–2011 (post-bubble). The hedonic models demonstrated a complexity in the determinant of housing prices during the housing peak-bubble period. The inclusion of submarket dummy variables in the hedonic models improved the amount of explained variation. The R2 values of the hedonic models from 2002 through 2008, followed by a decrease after the bubble-burst period. The pre-bubble-burst trend in R2 suggests that predictable market forces were at work; partly driven by irrational expectations of housing buyers and the perceptions of run-away housing prices during the growth phase of the bubble.  相似文献

北京市景观可达性与住宅价格空间关联   总被引:2,自引:0,他引:2  
随着城市居民对住宅环境要求的不断提高,城市景观对城市住宅价格分异影响日趋显著。分析景观对住宅价格分异格局的影响,可为城市住宅空间结构的规划提供依据,为规划与管理部门提供决策参考。以北京城区二手房小区为样本,基于ArcGIS空间分析方法和特征价格模型,探讨景观因素对北京市住宅价格空间分异格局的影响。以主流房地产交易网站二手商品房报价资料为基础数据,共采集到2012 年1 月北京市城六区有效住宅小区样本3174 个,对住宅样点进行空间化处理,并建立住宅空间信息数据库。运用密度分析、空间插值等方法,分析北京市住宅空间分布特征与价格空间分异格局。核密度分布图显示:北京市住宅空间分布呈现显著的向心化与离心化并存现象,总体上以天安门为中心向周边呈衰减趋势,在地铁转换站点形成了多个集聚次中心。在此基础上,从住宅属性、交通因素、区位特征等方面选择主要解释变量,构建地理加权回归模型,对住宅价格影响因素进行分析,重点探讨景观可达性(如绿地、水景、山景等)与住宅价格的关联。结果表明:次中心与住宅价格关联最为显著,绿地、水景、山景与住宅价格存在一定程度关联。其中,山景和高绿化率对住宅价格增效明显;由于水质较差,北京城六区内河流与住宅价格存在负相关;污水处理以及丧葬场所等污染源与住宅价格也存在显著负相关。远离污染源、靠近宜人景观、低容积率、高绿化率是居民选择住宅的需求。  相似文献

以住房子市场理论为框架建立研究假设,用主成份分析和聚类分析法刻画厦门市的住房市场特征。对住房类型子市场与聚类划分子市场进行对比分析,并采用Hedonic多重回归法对不同子市场划分方式的合理性进行验证。在此基础上,采用特征价格函数和子市场样本密度分布展开空间分析。结果显示:厦门市区划分为四个住房子市场,由城市中心地区向外呈现非均衡的层级化空间分布特征。城市中心与外围局部地区子市场的极化分布形成了"空间分割",降低了住房消费的空间替代性。多元产权结构下的市场环境、非均衡的住房用地拓展以及缺乏弹性的住房开发控制共同导致了空间分割。充分认识住房市场的结构与特征,将有助于提高城市住房公共政策的效率。  相似文献

Accessibility is considered to be one of the most important determinants of use and land-cover change. In rural land-use change studies, the accessibility situation is often described by simple measures of the distance to a location of interest. In this paper, different measures of access are tested for a rural area at the forest fringe in the northeastern Philippines. The accessibility measures addressed range from simple distance measures to land-use type specific transport costs and a population potential measure. The different measures are tested based on their capacity to explain the spatial pattern of different land-use types. A comparison of the findings based on a spatial analysis and an analysis of household level data is made. It is concluded that the relation between land use and accessibility is dependent on the specific characteristics of the different land-use types. The (dis-)advantages of the use of the different accessibility measures are discussed.  相似文献

随着中国城市轨道交通的大力发展,城市轨道交通对沿线住宅价格的影响引起广泛关注,探索其时空效应有助于预测未来新建轨道交通的影响以及帮助政府制定合理的房价调控和城市土地利用政策。以福州地铁1号线为例,探讨城市轨道交通从建设前到建成运营的过程中,对站点周边2 km范围内住宅价格产生的时空效应。结果表明:① 城市轨道交通沿线住宅价格受到区位、邻里、建筑等多方面因素的综合作用,其中,城市轨道交通对沿线住宅价格有显著的增值效应,中高价位住宅市场受到城市轨道交通的影响最为明显。② 空间维度上,住宅价格随着与轨道交通距离的增大而呈现不同程度的递减,至轨道交通站点距离每减少1 km,住宅价格增加5.1 %。轨道交通对沿线住宅价格具有显著的分市场效应,中心城区市场的影响半径大于非中心城区市场,平均空间影响范围为1.5 km;而非中心城区市场的影响强度要远高于中心城区市场,在400 m范围内住宅价格受到轨道交通的影响最大。③ 时间维度上,城市轨道交通在建设期和运营期对沿线住宅价格均呈现出正向影响,且运营期对住宅价格的影响显著高于建设期,运营期相较于建设期平均涨幅达19.63 %;同时,轨道交通的开通给住宅价格带来的效应远大于调控政策以及宏观经济因素的影响。  相似文献

目前关于城市住房价格异质性和影响因素研究多侧重于空间位置分析,从城市系统角度刻画住房价格分异现象有待进一步探索。根据“土地利用—交通相互作用理论”,城市空间的发展过程是各类活动通过交通相互作用的过程,本文构建了交通可达性模型,综合全市经济活动空间分布和交通网络评价城市区位条件,并以北京为例,从就业、教育、消费、医疗服务等各方面评价了城市区位条件,在此基础上依据家庭成员结构,模拟分析了家庭区位需求对住房价格的影响。案例研究表明,本模型对房价的模拟可以在全市范围内达到很好的效果;家庭的区位选择决定着住房价格的空间格局;各类活动中就业对北京市房价分布影响最为显著,其次是消费、教育,而医疗服务对住房价格影响相对较弱。此外,本文所提出的模型系统阐述了城市经济活动分布格局对住房价格的影响,经济活动分布发生变化时模拟结果随之变化,因此,本模型可以进一步拓展用于“以业带人”政策实验,模拟分析疏散各类经济活动后住房价格的变化,也为城市房价及土地市场分析研究提供模型方法上的参考。  相似文献

长春市区新建住宅价格的空间格局分析   总被引:2,自引:0,他引:2  
刘颖  张平宇  李静 《地理科学》2011,31(1):95-101
利用GIS技术对长春市住宅价格空间格局进行了研究,发现长春市住宅价格空间格局整体呈现单中心圈层分布,在长春市动植物公园与南湖广场附近分别出现了2个价格极核;住宅价格次高区域位于城市中心,包含了南湖与伊通河部分段;住宅价格变化幅度区域差异明显,东北—西南方向价格降低速度快,东南—西北方向价格降低慢,并且在城市西部和南部出现了局部高价格区域。在此基础上,分析了长春市住宅价格空间格局的驱动因素,发现住宅价格空间格局主要受到居住环境优势、城市发展战略、交通条件、用地布局及购买主体收入水平等几个方面因素的影响。结合研究结果,对长春市房地产开发格局优化提出了几点建议。未来长春市住宅开发的重点区域将集中在南部、西部和东北部。南部和长东北地区适宜进行中高端生态社区的开发,西部新城应以普通住宅与生态社区开发相结合,铁北地区应以低端住宅建设为主。  相似文献

住房市场化与较高住房需求带来住房价格的迅速提升,进而引发住房可负担性下降等问题,租赁住房逐步成为居民的另一主要择居方式。城市交通作为重要因素之一,对住宅租赁价格的影响仍需深入探讨。论文以北京市为例,运用交通网络中心性指标,研究道路网络及公共交通网络对住宅租赁价格影响的空间差异。结果表明:① 以出行时间为基础构建交通网络,公交网络总体拟合程度高于道路网络;公交网络中邻近中心性即相对可达性拟合程度最高,而道路网络中介中心性即中转功能拟合程度最高;② 城市中心-城市中部-城市外围的环状结构中,中心性影响程度存在空间差异,道路邻近中心性及公交各类中心性对城市中心及中部具有重要影响,城市外围主要受道路邻近中心性及介中心性影响;③ 基于拟合程度最高的公交网络邻近中心性的影响模式分析,综合交通枢纽、轨道交通换乘站点、轨道交通站点、重要地面公交站点等在城市中心及中部对租赁价格影响较高,而城市外围仅轨道交通站点及换乘站点影响较高;④ 道路设施网络与公交组织网络结构特性导向下的驱动力差异、交通网络各功能空间效应的区位指向、城市不同空间重要基础设施建设的外部效应差异促进了道路与公交网络中心性对租赁价格影响的空间分异。  相似文献

针对以往住宅价格影响因素分析中忽略城市路网形态参数的问题,该文基于空间网络分析,将不同搜索半径下道路接近度与穿行度纳入住宅价格特征变量,构建空间计量模型,探究成都市路网形态对住宅价格的驱动效应。结果表明:1)相比享乐回归模型和地理加权回归模型,多尺度地理加权回归模型揭示了不同变量的空间影响尺度,更适用于探究成都市路网形态对住宅价格的影响;2)路网的局部接近度、局部穿行度核心位于二环内,全局接近度核心主要分布在四环内,全局穿行度核心主要分布在交通干道上;3)不同搜索半径下对住宅价格具有显著驱动效应的接近度均为全局尺度变量,该效应在空间上相对平稳,而穿行度作为局部变量,其在空间上的影响尺度随搜索半径的变化而存在差异,具有一定的空间异质性,其中,路网接近度对住宅价格产生正向影响,其系数空间格局呈跨尺度相似特征,而穿行度产生负向影响,其系数空间格局呈跨尺度变异特征;4)各搜索半径下路网形态变量的差异可在一定程度上改变消费者对其他影响因素的偏好程度。  相似文献

This study identifies the spatial pattern of housing price changes and their determinants in Seoul and its neighbouring new towns. The results of a cluster analysis show that the spatial pattern of housing price change rates is nor correlated with housing prices. It is found that housing price change rates vary with the Chonse price index and money supply, building permit area, stock price index, and yield on 3 year corporate bonds. It is also shown that the more apartment units that are built in a region, the lower the housing price change rate.  相似文献

城市街道网络是承载人们日常行为的空间载体,街道网络及其中人的日常行为共同构成了主要的街道网络空间环境,并影响着犯罪行为的发生。既有研究表明街道空间中多发“两抢一盗”侵财类案件,并且街道网络形态和日常行为主体与犯罪存在联系,但对这一问题的深入探究较少。本文基于HS市原DP区的派出所辖区单元,使用路网数据、人口统计数据、手机信令数据等相关资料,采用空间分析和统计分析方法,对街道网络的几何形态和拓扑形态、动态人口和静态人口等因素与犯罪分布的关系展开分析,尝试探索街道网络空间环境对“两抢一盗”犯罪的影响。结果表明,街道网络空间环境中影响盗窃和两抢犯罪的要素存在较大差异。“X形单元”式街道网络、路网密度、低速交通的路网渗透性、静态人口密度和动态人口密度均对盗窃犯罪产生重要影响,与两抢犯罪相关的仅有“T形单元”式街道网络、静态人口中的实际居住户籍人员和外来人员密度,街道网络形态没有表现出与两抢犯罪的显著相关。最后提出,由于街道网络的通达性和危险性往往并存,如何通过调控或改善整体的街道网络空间环境来尽可能减少犯罪风险,是未来规划建设安全的街道网络空间需要思考的话题。  相似文献

Factors of spatial distribution of recreation areas in peri-urban Beijing   总被引:1,自引:1,他引:0  
Based on the case study of peripheral urban areas in Beijing, this paper aims to identify the factors which will influence the spatial distribution of peri-urban recreation areas, by analyzing the collected data from questionnaires, online survey, documentation and field investigations (2007). In order to achieve sound information, relevant data from different management departments, owners and land-use types involved in the case study area are collected. A sampling database for peri-urban recreation areas in Beijing is established, and GIS spatial analyses as well as statistic analyses are applied. The result indicates that spatial distribution of recreation areas is majorly influenced by four factors, e.g. tourism attractions and environmental conditions, policy and spatial governance, consumption demand and preference, land price and availability. Tourism attractions and environmental conditions are dominant factors for public recreation areas. Commercial recreation areas are highly related with accessibility. Agricultural recreation areas are usually attached to special farmlands near large-scaled scenic areas. Meanwhile, recreational business clusters have appeared in suburbs influenced by mass recreation market growth. Controlled by the land price, commercial recreation areas are differentiated on their scales and developing intensity. Policy and spatial governance have made arrangements of recreation areas more balancing and more human-oriented. A peri-urban recreation area model is therefore established on the basis of this analysis, which can guide urban planning and designing, land-use planning and recreation resource development.  相似文献

基于北京市9个不同类型中低收入社区的600位就业者的问卷调查数据,通过构建多元线性回归模型,验证了住房机会(住房搬迁机会)以及就业机会(工作单位类型)等市场转型过程中的制度性因素对中低收入者就业可达性的影响。研究表明,北京市中低收入居民中,国有企业单位及非国有企业单位就业者相对于行政事业单位就业者,显著地承受更大程度的职住分离,体现出单位制度残留的持续影响。由于政府保障性住房项目而搬迁的中低收入居民职住分离程度最大,而因个人原因发生居住搬迁的中低收入者职住距离则相对较近。拥有北京市户口的本地内生型中低收入者、非户主低收入者、男性低收入者的职住分离程度显著更大。最后,北京市中低收入者的月收入与其职住距离成显著正相关,表明市场因素开始发挥作用,但当考虑了住房搬迁机会变量后,部分市场化因素的影响不仅减弱并且变得不显著,而制度性因素的影响变得更强且统计上显著。由此说明,对于转型期的城市中低收入者而言,计划经济下再分配制度的残留与路径依赖以及城市空间的结构性调整对其职住关系的影响更为显著。  相似文献

Amenity value in post-industrial Chinese cities: the case of Nanjing   总被引:1,自引:0,他引:1  
Many Chinese cities are in a transition from industrial to post-industrial urban economies. In this process of urban restructuring, land use becomes polycentric and fragmented. More sophisticated models are needed to estimate the amenity effects of this complex residential environment. This article assesses the relative housing price effects of neighborhood characteristics and accessibility in Nanjing, China. This is achieved with a hedonic price model that incorporates detailed spatial measures, geographical contingency, and a modified version of Alonso’s (1964) general theory of land rent. A crucial finding is that the effect of job accessibility on house price varies depending upon the specific sector of employment. Accessibility to jobs in the public and private service sectors has strong positive effects. However, housing proximity to heavy industries has a spatially nonlinear effect: negative in close proximity, but positive at a larger distance. Second, when we control for job accessibility, access to public transport has an added positive effect. Finally, neighborhood “quality” (defined in terms of nearby amenities) is also relevant, but far less than access to service employment. This research shows that Nanjing’s housing prices are affected by different residential characteristics than those with dominant price effects in Western cities.  相似文献

城市房价与地价之间的关系错综复杂,不仅受多种因素的交织影响,相互之间也存在动态关系。研究房价与地价关系的传统方法,如Granger因果检验和回归分析等,无法刻画房价与地价之间多维的网络状关系,相比之下,结构方程模型能同时处理多个内生潜变量,且不受观测指标共线性的影响,为刻画地价与房价的交互作用提供了新的工具。从住房与土地市场的供需传导机制出发,推导出房价与地价的结构模型,以北京市为例,运用2003-2013年居住用地价格和2014年在售楼盘价格,与北京市GIS电子地图相匹配,提取商服中心可达性、公共交通可达性、道路可达性、商服繁华度、设施便利性等解释变量,构建地价与房价结构方程模型,分析二者之间的结构关系。  相似文献
