The differential geography of housing affordability in Sydney: a disaggregated approach

ABSTRACT

Despite extensive studies being devoted to housing affordability in Australia, few have investigated housing affordability at a disaggregated level. This is in spite of the fact that there are existing socio-economic and demographic disparities across different regions of a city. This study aims to fill this gap by examining housing affordability in Sydney, a city that is characterised by diverse demographic and socio-economic mix, from a sub-city perspective. Two dimensions of affordability are assessed from 1991 to 2016: entry-level and ongoing housing affordability. The study finds that entry-level housing remains extremely unaffordable in all regions of Greater Sydney, although the level of unaffordability varies across regions. Specifically, the deterioration in housing affordability is more obvious in low-income regions such as Western Sydney. In addition, the ongoing housing affordability of those who have entered the market improves considerably within 5–10 years, although there are significant variations between different regions. Importantly, residents in low-income regions such as Western Sydney take a longer period to improve their ongoing affordability. The findings of differential geography of housing affordability have some profound policy implications. Policymakers should consider the disparities across different regions by formulating a more targeted and regionally balanced housing policy.     

中国城市房价对生育率的影响——基于长三角地区41个城市的计量分析

房价与人口的关系是人文经济地理学研究的热点领域,本文选取长江三角洲地区作为研究区域,利用区域内41个城市11年（2008—2018年）的数据,分别采用差分GMM模型及LSDVC法,从整体和分组的层面分析城市房价与生育率的关系。整体模拟结果表明,城市房价上涨的速度对于生育率有着显著的负向作用：房价上涨得越快,生育率下降得越快。同时,以房价收入比衡量的居民购房能力对生育率也有着显著的影响,居民购房能力下降得越快,生育率也下降得越快。分组研究的结果表明,不同房价水平的城市,生育率受购房能力影响程度不同,中等房价水平及较低房价水平的城市,其生育率更容易受到购房能力波动的影响。基于以上研究结果,提出严控房价涨幅速度、适当提高购房补贴、提高居民收入等政策建议,以期提高区域内居民整体生育意愿,促进人口增长。     

廉租住房居民的时空间行为特征——以福州市橘园洲社区为例

基于2020年12月福州市橘园洲社区居民的问卷调查结果与48 h活动日志,结合时间地理学理论,采用GIS 95%标准置信椭圆、点密度与叠置分析方法,从微观个体角度研究保障性住房居民工作日与休息日的工作、购物、休闲3类活动的空间特征及其对附近空间的利用情况,并使用多元线性回归分析其影响因素。结果表明：1）案例社区居民在工作日与休息日的活动空间差异较大,休息日居民内部差异大于工作日。2）从不同活动类型看,工作日活动内部差异性较小,整体呈现通勤距离短、依赖社区周边的特性;购物与休闲活动在工作日依赖社区周边,而在休息日均具有明显的空间拓展,且出行人数呈距离衰减。3）居民工作日活动受通勤距离、年龄与收入的显著影响,休息日活动受收入、家庭结构与文化程度的显著影响。4）与一线城市保障性住房选址在城市边缘集中的趋势不同,福州市仍有足够的空间使保障性住房的选址相对均衡。     

南京市住房困难人群职住关系及影响因素分析

居住和就业的空间关系,既是城市居民日常生活的空间反映,也是评判城市空间合理性的重要准则。新就业大学生(取得专科及以上学历且工作未满3 a,在南京无自有住房且租房居住)、外来务工人员(收入低于2016年南京市人均可支配收入4166元/月,在南京无自有住房且租房居住)和中低收入人群(南京户籍,家庭人均可支配收入低于3074元/月,人均住房面积不大于20 m ²)等住房困难人群,普遍面临住房机会不平等的问题,职住关系也呈现出特殊性。论文基于南京市这3类住房困难人群的873份问卷数据,采用两步聚类法对通勤流向模式进行划分,基于多项Logistic回归模型探究通勤时间和通勤方式的影响因素,并以南京鼓楼区为案例解析住房困难人群的职住关系。结果表明：新就业大学生通勤流向主要为内部通勤,通勤时间最短,职住关系受通勤流向和工作单位影响;外来务工人员通勤流向主要为侧向通勤,通勤方式机动化程度最低,职住关系受通勤流向、工作单位和性别显著影响;中低收入人群通勤流向主要为侧向通勤,职住分离程度最高,职住关系主要受到住房类型的显著影响。以鼓楼区为例,论文进一步发现新就业大学生以交通条件为导向、外来务工人员以工作地为导向和中低收入人群以居住地为导向的职住关系。     

Capital and conscience: poverty management and the financialization of good intentions in the San Francisco Bay Area

Social impact investing differentiates itself from traditional investing by claiming to create public social benefits alongside private profits. Globally, municipal governments are increasingly looking to this model to fund urban social services and poverty management. Through a case study of social impact investing in affordable housing in the San Francisco Bay Area, I deconstruct the financial and ideological underpinnings of this model to understand how private profits are drawn from local geographies of impoverishment. Analyzing social impact investing as a poverty politics reveals how it places preexisting, state-subsidized systems of poverty management into social impact investing portfolios, dividing impoverished spaces into new hierarchies of deservingness by incorporating private investors’ visions of what will help low-income tenants. But these processes also fail to subsume social life within housing financed in this manner, as tenant practices subverting those idealized by the state and investors persist alongside the generation of private profits.     

城市居住小区环境归属感评价——以大连市为例

研究居民对居住小区环境归属感,进行定量评价并揭示其规律,可为指导城市小区规划设计提供依据。本文以调查问卷的形式,对大连市的居住小区进行调查,充分考虑评价因子的代表性和多层次性的特点,选取5项一级指标和25个单项指标建立评价指标体系;采用层次分析法与地理信息系统软件Surfer 8.0相结合的方法,对大连市居住小区归属感进行初步评价。研究结果表明:影响居住小区归属感的主要因子有舒适感、识别感、安全感、交流感、成就感;大连市居住小区归属感的整体评价较好,市内四区存在差异;归属感的高值区域分布在生态环境风景区、商务活动中心、靠近海岸线的地方及交通便利的地方。     

收缩城市住宅价格空间分异及影响机制——以鹤岗市为例

收缩城市的经济社会问题逐渐凸显,住宅市场发展呈现出消极态势,房价变化成为社会关注的焦点。在此背景下,论文以典型收缩城市——黑龙江省鹤岗市为例,基于住宅小区、夜间灯光、POI数据,利用Kriging插值和多尺度地理加权回归模型等方法,结合鹤岗市空间增长与收缩情况分析住宅价格空间分异特征及影响机制。结果显示：① 鹤岗市住宅价格呈圈层模式分布,核心—外围分异程度强。高水平住宅价格小区集聚在核心区内且分布规模小,中高值圈层扩散态势弱;外围工矿型辖区收缩情况相对严重,住宅价格水平低且波动小。② 城市发展状态与住宅价格水平存在空间相关性。不同收缩程度区域经济发展态势、居民收入水平、人口减少与老龄化、保障房建设规模等宏观因素差异影响着住宅价格总体空间分异格局。③ 城市内部区域的增长或收缩状态影响微观设施的作用效果。发展中心的区位优势对增长型区域住宅价格的正向作用更强,高水平公共服务对核心区和城市北部收缩区域住宅价格的增长有明显积极效应,企业工厂的分布对增长型区域住宅价格的负向影响更突出,各因素相互联系、交互影响,共同作用于住宅价格空间分异。     

Transplanting cityscapes: the use of imagined globalization in housing commodification in Beijing

How does globalization unfold in the process of urban development? Rather than examine the impact of globalization on the city as if the former were independent of and superimposed on the latter, this paper aims to address how globalization can be imagined, pursued and exploited in the process of local growth. Through examining the emergence of Western architectural motifs in a late socialist capital, Beijing, it is shown that transplanting cityscapes is a conscious action by developers to exploit globalization and thereby overcome the constraints of local markets. By associating themselves with globalization, the development elite hope to sell the vision of the good life in the era of globalization.     

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

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.     

Ethnic Capital and Assimilation to the Great Australian (Homeownership) Dream: the early housing experience of Australia's skilled immigrants

We use the Longitudinal Survey of Immigrants to Australia, 2005–2006, to examine the housing tenure experience of skilled immigrants to Australia 6 and 18 months after arrival for relationships with ethnic capital (cultural background), visa category streams, aspects of human capital, demographics, social capital and discrimination. Homeownership experience is used to indicate integration into Australia's dominantly middle-class society. Multinomial regression analysis identifies visa entry category as the most important independent group of variables accounting for immigrants' short-term dwelling tenure, followed by aspects of human capital, family status, and the importance of ethnic capital for immigrants of both English-speaking and non-English-speaking backgrounds, and discrimination.     

Multiscale geographically and temporally weighted regression: exploring the spatiotemporal determinants of housing prices

Understanding scale effects is important and indispensable for geography studies. However, spatial and spatiotemporal statistical tools for measuring the operational scales of different processes are rather limited. This article extends the popular geographically and temporally weighted regression (GTWR) model to consider operational scale effects by proposing multiscale GTWR (MGTWR), which offers a flexible and scalable framework for identifying and analysing multiscale processes by specifying flexible bandwidths for various covariates. Then, MGTWR is employed to explore spatiotemporal variations and how influential factors are associated with housing prices in Shenzhen. This article attempts to extend GTWR to MGTWR in consideration of scale effects, thereby highlighting the importance of different levels of spatiotemporal heterogeneity. Furthermore, the empirical results of this study can provide valuable policy implications for real estate development in areas where urban planning should address multiscale effects in both temporal and spatial dimensions.     

城市景观对住宅价格的影响——以杭州市为例

优美的城市景观是人们日常生活休闲、娱乐的场所, 给人们带来心理上的愉悦和舒适感, 对城市的品质内涵也有重要影响。由于大多数景观效益是隐性的, 其舒适性价值难以用货币价格直接测量, 国内外学者广泛采用特征价格法进行实证研究。本文以杭州市为例, 从建筑、邻里、区位、景观四个维度选择25个解释变量构建特征价格模型, 定量评估了城市内部各类景观对住宅价格的影响。实证结果表明:住宅价格与到西湖和公园的距离呈负相关关系, 而与公园的面积呈正相关关系:其中, 到西湖和最近公园的距离每增加1%,住宅价格将分别下降0.240%和0.036%;公园的面积每增大1%,附近的住宅价格则提高0.012%;广场、山景、钱塘江等景观也对周边一定范围内房价具有显着的提升作用。     

长三角地区住宅售租比时空格局演变及影响机制

中国住宅租赁市场与住宅买卖市场的不对称发展,使住宅租金与住宅价格过度偏离,不利于住宅市场的健康发展,从住宅售租比视角切入住宅研究对解决"住有所居"问题具有重要意义.以长三角三省一市县级单元为研究区域,利用LISA时间路径和时空跃迁等方法,分析2008-2018年长三角住宅售租比的时空格局及演化特征,运用地理探测器模型探...     

转型期广州市生命历程与住房产权转换

作为家庭生命历程中的重要事件,住房产权转换与家庭特征变化、个人与工作单位的关系以及区域住房市场环境变化紧密相关。采取事件史分析方法,将住房产权转换与个体生命历程中的重要事件关联起来,分析住房产权转换的影响因素。对住房产权转换的持续期的研究发现,处于租房状态下的住户改变产权状态的愿望较强,但产权一旦进入自有状态,居民改变产权的愿望就会降低;从住房产权的生存时间来看,最终向全部产权转变的生存时间最长,其次是向资助产权的转变,最短的是向租房产权转变;通过建立COX’s比例风险模型分析发现,家庭生命周期变化和组织变量对住房产权转换的影响都非常显著,说明在中国特殊背景下,住房产权的转换不仅与家庭基本特征变化密切有关,还与个人单位的基本特征密切相关,这正是转型时期计划体制和市场分配体制双重力量相互作用的结果。     

Mexican and Central American immigrant communities in the boom and bust housing markets of the 2000s

Classic immigrant enclaves, largely voluntary and temporary, have historically served as a strong platform for integration in United States metropolitan areas. However, trends in the early 2000s, including new destinations and skyrocketing housing costs, may have reshaped the landscape, particularly for numerically dominant immigrant groups with very low socioeconomic status. In this article, I use data for 56 metropolitan areas and 31,563 census tracts from the 2000 Census and the 2005–2009 American Community Survey to examine the relationship between the change in concentration of Mexican and Central American immigrants and the characteristics of neighborhoods in 2000. The analyses suggest that, across metropolitan areas, these immigrant communities consolidated in neighborhoods with low home values, adequate but overcrowded housing, relatively small shares of their own immigrant group, and large shares of other Hispanics. Demographic dynamics may have weakened immigrant support networks, leaving Mexican and Central American immigrants vulnerable, particularly in a subset of metropolitan areas where this population grew most substantially outside the central cities.     

跨地区生计及其变迁视角下流动人口城镇住房分层的特征及其影响因素

在跨地区生计及其变迁的视角下,将流动人口在流入地和流出地城镇的住房状况有机结合,借助2016年中国流动人口动态监测调查数据和相匹配的城市特征数据,运用描述统计和多层次回归模型,探究流动人口城镇住房分层的特征及其影响因素。结果发现,流动人口的城镇住房已形成了一个从低到高依次由无城镇产权房、有城镇产权房（流出地或流入地城镇产权房）和多区域城镇产权房构成的“三阶四级式”的“金字塔型”结构。模型结果显示,流动人口个体及家庭的社会经济条件和流出地的区位禀赋是其实现城镇住房自有的重要基础和财务支撑,流入城市的经济发展水平、房价和城市规模仅对流入地和多区域城镇产权房有显著影响。因此,本文挑战了流动人口住房条件差的刻板印象,并吸引人们关注流动人口跨地区生计及其变迁对其城镇住房的影响,拓展了当代中国城镇住房分层研究的视角。     

Deconstructing consultative frameworks: the case of staff housing provision in Burringurrah,Western Australia

Housing for government‐employed staff in remote Aboriginal communities is a topic that raises considerable debate amongst those whom it affects. Striking at the heart of Australia's effort towards reconciliation and a legacy of policy failure, debate regarding standards and siting of staff housing is highly political in nature. In Burringurrah, Western Australia, two government agencies recently undertook projects to provide staff housing within the community. Each agency approached its projects differently, but in both cases response at the ‘grassroots’ level was negative. This paper argues that a primary, but indirect, influence on ‘community’ satisfaction was the ideological structure of each agency. It follows, then, that understanding this organisational context is crucial to achieving more appropriate housing outcomes in the community.     

商品住宅价格空间溢出效应测度及其影响因素分析——来自长三角地区的证据

商品房价格的空间溢出效应是当前学界探讨的重要议题,但鲜有研究基于区域视角测度并对比不同商品房价格空间溢出效应的差异。本文以长三角地区为例,基于GIS的空间计量模型尝试测度商品房价格的空间溢出效应,并进一步对比分析三种商品住宅（新住宅、二手住宅和租赁住宅）价格的空间溢出效应及其影响因素。结果表明（：1）上海、杭州和南京三个城市的商品住宅价格明显高于其他城市,说明其价格与城市的经济（行政）等级密不可分（;2）三种住宅价格均表现为由上海向内陆区域依次降低的空间规律,具有明显的空间等级性（;3）新住宅、二手住宅和租赁住宅价格的空间溢出效应依次减弱,但新住宅和二手住宅价格的溢出效应差别不大（;4）上海、苏州、南通和嘉兴四个城市处于高房价集聚区,该区域商品房价格与周边城市的商品住宅价格存在显著的空间溢出关系（;5）经济基础、消费需求和社会资源对三种商品住宅价格的空间溢出均具有显著的促进作用。     

Public perceptions of foreign and Chinese real estate investment: intercultural relations in Global Sydney

Moving foreign human and financial capital through landed property is not a new phenomenon in Sydney. It is a recurring geopolitical strategy that is replete with intercultural tension and deep colonial roots. In contemporary Australia, there is an assumption in public policy and media rhetoric that there is a high level of public concern about foreign investment. However, there is little empirical data that examines public perceptions. In this study, we are interested in whether the dominant voices in this debate represent broad public views about this issue. We sought to fill this gap by conducting a survey of almost 900 Sydney residents, looking at their perceptions of foreign and Chinese investment. We find high levels of public concern and discontent about foreign investment amongst Sydneysiders, with Chinese investors being a key target of this discontent. In the context of high housing prices in Sydney, there were widely held concerns about housing affordability. Survey respondents had a sophisticated understanding of what influences house prices, but with an overemphasis on the role of foreign investment. There is a general lack of support for policy that encourages foreign investment, and a lack of confidence in how the government is regulating foreign investment. Half of our participants reported that they would not welcome Chinese foreign investment in their suburb.
