中国城市房价快速增长背景下,城市房价、收入与房价收入比空间格局既有相似性,也表现出差异性,其空间异质性与空间依赖性特征显著。本文以中国337个地级行政单元为研究对象,运用泰尔指数、位序-规模和空间马尔科夫链等方法,对2009—2018年中国城市房价、收入和房价收入比的时空分异格局、整体稳定性和空间依赖性特征进行分析发现：① 中国城市房价增长呈现出波动性特征,整体分异程度增强,房价城市体系呈现“金字塔型”结构,收入则表现出平稳增长态势,整体分异度降低,城市体系呈现“橄榄型”结构,在房价与收入共同影响下,房价收入比整体差异性显著加强;② 城市房价空间格局表现出“地带性”与“等级性”差异并存,而收入更多表现出“地带性”差异,房价收入比则以“等级性”差异为主;③ 城市房价和收入类型的稳定性和空间依赖性较强,高、低水平城市存在两极分化与“俱乐部收敛”现象,房价收入比稳定性相对较弱。对中国城市房价、收入和房价收入比时空分异格局和空间关联效应的分析,可以为探索中国城市房价收入比空间分异模式与机理提供必要研究基础。  相似文献   

Unraveling the multi-scalar residential segregation and socio-spatial differentiation in China: A comparative study based on Nanjing and Hangzhou   总被引：1，自引：0，他引：1

Residential segregation is a dual process of socio-spatial differentiation in residents and spatio-temporal heterogeneity in dwelling.However,most of the existing studies are es-tablished from the single perspective of urban residents based on demographic data,which is difficult to reveal the dynamics and complex spatial reconstruction within and between cities.With the characteristics of both stability and timeliness,the rapidly changing housing market is one of the processes and results of socio-spatial reconfiguration,and it is undoubtedly a better lens to observe residential segregation.This paper adopts methods such as multi-group segregation index,multi-scalar segregation profiles,and decomposition of segregation index,with Nanjing and Hangzhou as case cities,and establishes multi-scalar segregation profiles and comparative models based on three geographical scales of census tract,block and grid,and different residential types.A quantitative study was conducted on the degree and pattern of multi-scalar residential segregation in Nanjing and Hangzhou from 2009 to 2018.The pa-per found that the spatial segregation index is an improvement of the non-spatial segregation index.There are differences between Nanjing and Hangzhou in the evolution process of residential segregation.Nanjing has a higher degree of spatial differentiation as a whole,among which spatial components have a more significant impact.  相似文献   

收缩城市住房空置时空分异及影响机制——基于居民用电量视角   总被引：1，自引：0，他引：1  

刘艳军  张艺宁  孙宏日  付慧 《地理科学》2021,41(12):2087-2095

以中国典型的资源型收缩城市——伊春市的伊春区为研究对象,从居民用电量视角对住房空置情况进行判定,同时综合运用核密度估计、网络分析以及问卷访谈等方法,基于区域、居住区、格网3种尺度,对2013—2018年住房空置时空分异格局及影响机制进行深入探究。结果表明：① 伊春区空置住房总量和空置率总体表现为波动上升态势,在国际通行标准下处于“供需基本平衡”状态;② 伊春区住房空置格局在区域尺度、居住区尺度、格网尺度等不同尺度下表现出一定差异性,但各尺度均总体呈现“核心?边缘”的空间分布特点;③ 人口流失、经济支撑、城市功能地位以及居民感知等因素影响伊春区住房空置时序演变,而城市空间开发扩展、住区建设演变、教育医疗设施布局、公共交通可达性等因素共同作用于住房空置的空间分异。  相似文献   

城市住宅价格空间分异的区域一体化因素分析 ——以河南省开封市为例     

蔡媛媛  朱英明  艾少伟 《地域研究与开发》2021,40(2):62-67

选取2001年、2006年、2009年、2016年4个时点的城市商品住宅交易数据,基于空间分析与计量模型等方法,对开封市住宅价格时空变化特征及其与区域一体化因素的关系进行分析。结果表明:开封市城区住宅价格空间分布由单中心模式向多中心结构转变,邻近郑州的金明区正成为房价“高峰”;跨界交通和新城规划等一体化因素对开封市住宅价格的影响较为显著,且影响力随着一体化推进而变化。其中,郑开大道对住宅价格的正向促进作用呈先增后降的特点,开通相对较晚的郑开城际轻轨对住宅价格有着明显的正向作用,而开封西郊金明区的快速扩张弱化了其潜在效应。这有效地证实了区域一体化对城市住宅价格有显著影响。  相似文献   

快速城镇化背景下居住空间分异与失地农民社会融合的作用机制研究——以长三角地区为例     

张海娜  朱贻文  邓晓翔 《地理科学进展》2021,40(1):135-146

伴随着快速城镇化进程,中国城镇化已从速度型向质量型转变,这一转变的核心是实现人的城镇化,即农业转移人口的市民化。失地农民的居住形态由原来的宅基地建房为主转变成征地补偿房、租房和自购商品房等多种形式并存,即出现了居住空间分异现象。居住空间分异对失地农民的社会融合会产生重要影响,但其作用机制的有关研究尚少。论文基于长三角地区的调研数据,以“社会—空间”为主要视角,从住房类型(含区位)和住房人均面积2个维度衡量居住空间,通过建立回归模型,分析居住空间对城郊失地农民社会融合的影响。研究发现,其作用机制为：一是不同居住空间的城郊失地农民的社会融合程度有显著差别;二是住房类型对城郊失地农民的社会融合影响最大,住房面积则影响不大;三是性别、年龄、职业、收入、获得非农户口的时间等因素也与住房类型共同产生作用。为推动失地农民的社会融合、提升新型城镇化的质量,可采取的措施有推行混合居住模式、增强就业能力以及政府增加投入提升城郊失地农民社会保障水平等。  相似文献

Analyzing Accessibility Using Parcel Data: Is There Still an Access–Space Trade-Off in Long Beach,California?     

Kevin Kane  John R. Hipp  Jae Hong Kim 《The Professional geographer》2017,69(3):486-503

This article analyzes the impact of changing housing and neighborhood characteristics on the accessibility of neighborhood businesses using Long Beach, California, as a case study. Although advocates of smart growth and New Urbanism encourage land use mixing, aggregate-level analysis can be too coarse to pick up on fine-grained aspects of urban streetscapes. This study uses assessor parcel records and a point-based business establishment data set to analyze city-wide patterns of accessibility from individual dwelling units to thirty-one types of neighborhood businesses, including grocery stores, service shops, drug stores, doctor's offices, and banks. Regression results compare parcel-level and neighborhood-level drivers of accessibility between 2006 and 2015 to gauge the aggregated effect of recent economic, demographic, and built environment changes on this aspect of urban spatial structure. Larger homes in older, multiunit buildings and higher income neighborhoods show substantial increases in accessibility to most establishment types, suggesting a trend toward both greater accessibility and larger dwelling units—despite the traditional trade-off between access and space. Although gradual increases in home and business density increased overall accessibility over this period, weaker neighborhood-level results indicate that this trend is less pronounced in high-poverty and non-white areas.  相似文献   

Housing differentiation and housing poverty in Chinese low-income urban neighborhoods under the confluence of State-market forces     

Shenjing He  Lin Liu  Gangbin Yang  Fenglong Wang 《Urban geography》2017,38(5):729-751

ABSTRACT

Based on a large-scale household survey conducted in six large Chinese cities, this study is among the first attempts to juxtapose factors related to institution, market, and demography to examine the complex patterns and mechanisms of housing differentiation and housing poverty in low-income neighborhoods, which are conventionally conceived as homogenous substandard settlements. Results of Theil indices and multivariate regression models convey several interesting findings. First, the forces of the market and the State have projected different impacts on various aspects of housing status. Institutional factors had significant impacts on some costly and durable housing indicators such as housing tenure and housing area, while market forces have swiftly transformed the most malleable aspects of housing conditions, such as housing facilities, and will eventually replace some institutional legacies. Second, within-group housing differentiation is more palpable than between-group housing differentiation, suggesting that low-income neighborhoods in large Chinese cities are fluid and heterogeneous. Third, different institutional elements have different impacts on housing poverty. The well-functioning market remuneration system helps reduce the risk of housing poverty, yet working poor remains a severe problem. These findings can inform policies promoting social mix and housing affordability.  相似文献

南京城市住宅“售租比”时空格局与分异机理   总被引：3，自引：0，他引：3

“售租比”是国内外学者测度房价健康水平或泡沫风险的关键指标之一。利用中国房价行情平台提供的南京居住小区2009~2017年期间分季度平均售租价格信息,采用GIS空间分析等方法,考察南京中心城区“售租比”空间格局与演变过程。研究发现：① 城市整体“售租比”随房价波动变化明显,2016~2017年间快速增长;② 分异度先降后升,以城区内部差异为主,城区间差异越来越小;③ 高“售租比”小区多集聚于河西新城、江北新区等房价增速较快的投资热点区域。南京住宅“售租比”过快上升和空间离散加剧,意味着城市房价快速增长的合理性在降低。从地租视角解读,绝对地租决定着城市整体“售租比”的高低,级差地租和垄断地租则影响着城市内部“售租比”的空间分异。“售租比”可为判断城市内部房价相对合理性提供重要依据,但能否通过该指标准确预判城市房价风险程度及空间格局尚有待深入研究。  相似文献
