HISTORIC PRESERVATION AND SOCIAL STABILITY IN SACRAMENTO'S OLD CITY

Sacramento’s Old City contains the CBD of a metropolitan area of 1.5 million people and adjacent residential neighborhoods housing 32,000 people. This essay reviews the evolving social character of the Old City, which has been the subject of substantial preservation efforts since 1960. Survey questionnaires sent to members of the Sacramento Old City Association (SOCA) in 1977 and 1992 reveal continuity in most characteristics and attitudes. Although SOCA is a largely white and upper-income organization, and although SOCA’s main policy thrust is to preserve the single-family housing stock of the Old City, the record of neighborhood social change over the past two decades shows limited gentrification and enduring economic, ethnic, and life-style diversity. Characteristics of the metropolitan area and of the locality-its inherited land-use patterns and building stock, traffic, and indistinct residential image-work against gentrification. The Old City continues as a physically and socially eclectic place, in contrast to more thoroughly gentrified central neighborhoods in other, larger and more globally oriented, American cities.     

中国城市建设用地扩张与财政收入增长的面板格兰杰因果检验

土地开发已成为当前研究的一个焦点,但是对“土地财政”现象的研究仍集中在其形成机制方面,而很少证实土地是否及如何推动了地方财政收入的增长。为此,本文基于《城市统计年鉴》（1985-2011） 的面板数据,构建面板误差修正模型和随机效应模型,运用格兰杰因果检验探讨城市建设用地扩张与城市财政收入增长之间的因果关系,并对“土地财政”的影响机制、区域差异和开发效率进行初步探讨。结果显示,从1995 年开始,中国城市的土地开发是推动其地方财政收入增长的格兰杰原因。但是这种效应主要为即期的影响,而对房地产开发和工业增值税的长期推动效果不太显著,这暗示了土地财政在中国有过度的倾向。从区域差异来看,土地开发对地方财政收入的推动幅度在中西部地区或在100 万人口以上的超大城市更大,且随城市规模的增加其影响效果更为显著。     

SALES TAX AS PROPERTY TAX RELIEF? THE SHIFTING ONUS OF LOCAL REVENUE GENERATION

Local governments are under pressure to develop alternative revenue sources to their already strapped property tax bases. Throughout the 1970s, municipal governments nationwide restructured their local taxes by substituing sales tax for property tax revenue. A tax accounting model identified two sources of sales-for-property tax substitution: changes in the tax rates and normal economic growth and decline. Most of the sales-for-property tax substitution experienced in Illinois city finance was attributable to economic change. The critical determinant of this substitution appreared to be the municipality's share of the regional retail market. Cities in higher density metropolitan areas were less likely to experience sales-for-property tax substitution through economic growth than those cities in lower density, less competitive environments.     

2000-2010年广州市居住空间结构演变及机制分析

首先运用因子生态分析方法对广州市2010年的居住空间结构与居住人口特征进行分析,提取出6个主因子并划分为9类居住区,得出广州市居住空间具有明显的分异性。然后与2000年的居住空间结构进行比较,归纳出广州市居住空间演变具有历史延续性、市场及政策因素影响突出、空间拓展与城市发展同步、整体居住空间呈现“圈层+扇形”融合发展等特征。根据不同的空间层次特征,概括出四种演变模式：中心区稳定发展模式、近郊区商品房拓展模式、远郊区糅合发展模式和特定区保障房镶嵌模式。探讨了广州市居住空间结构的演变机制,包括历史发展惯性、房地产发展带动、住房保障影响、城市规划引导等四个方面。最后结合国内其他大城市相关研究推导出转型期中国大城市的居住空间结构。     

Compact,concurrent, and contiguous: smart growth and 50 years of residential planning in the Toronto region

In this article, we use parcel-based land-use data to analyze 50 years of residential development in the Toronto region. We test two hypotheses: (1) Toronto’s form does not conform to conventional definitions of suburban sprawl and (2) Toronto’s suburban development shows high levels of continuity over time with relatively high densities and mixed housing types. Contrary to recent research suggesting a convergence of urban forms among North American metropolitan regions, Ontario’s robust planning system has created a distinctive, highly consistent pattern of residential development that has, for half a century, achieved many of the core goals of smart growth including relatively compact, contiguous, and concurrent development. This form continues to be automobile dependent, however, and is not producing many of the benefits ascribed to smart growth. Rather than continuing to adopt United States-inspired smart growth policies, a more ambitious set of initiatives will be required to address current regional challenges.     

国内外生命历程与居住选择研究回顾和展望

1970年代后生命历程分析成为贯穿居住选择微观研究的核心方法。住房权属选择和居住流动是西方居住选择微观研究的主要内容。西方研究大多为应用生命历程观念将住房权属转换和居住流动决策与家庭生命历程和住房市场中的重要诱因联系起来,发现家庭特征、家庭生命周期变化和住房市场环境等都是居住选择的重要影响因素。对比西方的研究,中国城市居住选择微观研究非常缺乏,一些研究发现除了家庭特征和住房市场特征外,政府和工作单位的影响非常大。     

加拿大的城市旅游开发评述

旅游业是加拿大发展最快的产业之一,加拿大也是国际上开展城市旅游比较成熟的国家,其城市和地方政府都把旅游业看作创造就业机会和增加税收的源泉。加拿大的城市旅游开发包括文化旅游、体育旅游、会议旅游三个主要方面。文章指出加拿大城市在城市吸引旅游者方面采取和其他商业活动类似的竞争手段,如参与市场促销、创建城市形象和建设基础设施等。30多年来城市增加了博物馆、体育运动场、会议中心和大型节事活动等项目吸引旅游者。这些投资重新塑造了城市结构,城市旅游景观也已经有了雏形。本文对此作出了评述。     

A Severance Tax Revenue Forecast Model for Louisiana

Most states levy severance taxes on the value of natural resources when they are severed or extracted from the ground or subsurface. In Louisiana, severance tax on oil and gas production contributes to the majority of mineral revenue in the state, and over the last decade, has ranged between $400 million and $1.1 billion, or between 5 and 9% of annual state revenue. The purpose of this article is to develop a forecast model for severance tax revenue to better understand the severance tax regime and to assist in state budgeting and planning purposes. We couple an oil and gas production model with empirical relationships describing historical severance tax receipts to perform the forecast. We demonstrate that oil production correlations are robust, but that in recent years, unconventional gas production from the Haynesville shale has led to a significant departure from historic trends. We estimate that cumulative oil and gas severance tax revenues during 2011–2015 will range from $1.0 to $2.1 billion for oil and $1.3–$1.9 billion for gas. Louisiana is transforming into a gas-producing state, and more attention needs to be paid to tax design and the impact of exemptions on future severance revenue receipts.     

北京经济适用房布局特征及影响因素研究

20 世纪90 年代,中国开始实施经济适用住房政策。然而,在政策的实施过程中,由于不合理的布局,经济适用住房并没有切实解决中低收入家庭的住房问题。学者们通过研究发现,大多数经济适用住房被安排在城市边缘地区,缺乏配套公共设施。目前,相关研究较多关注经济适用住房的空间布局及其引发的社会问题,少有学者关注影响经济适用住房布局的因素。因此,本文试图从地方政府的视角解答影响经济适用住房布局的因素。研究提出假设,地方政府受到土地财政收入的驱动,将经济适用住房项目布置在对土地收益损失最小的地方,同时兼顾政策实施过程中的拆迁压力、住房市场结构以及公共交通便利性等。在假设基础上,对北京经济适用住房空间布局的时空特征进行分析,并构建经济适用住房布局的影响因素模型。结果发现：1999-2009 年间北京经济适用住房建设速度放慢,同时呈现向五环以外扩散及向某些点集聚的趋势;模型结果证实土地价格是政府在落实经济适用住房项目时考虑的重要因素。     

Assessing the influences of service provision on pace and short and medium term development patterns of residential housing in Dar es Salaam

The connection between city development patterns, housing and service provision is critical as it affects allocation of scarce resources in the cities of Sub Sahara Africa, where the adopted planning models and concepts seem to have minimal success. Through spatial analysis and quantitative research this study explores sequencing of servicing and housing development as it impacts city spatial growth patterns in a context of resource deficiency in Dar es Salaam City. The study finds that despite households’ land ownership being crucial in city spatial expansion process towards residential house ownership, their actual construction and occupation will depend on the accessibility of services. Moreover, it was established that as more services become available, proportionally, number of people settling in new areas increases. Since this process happens equally in planned and unplanned settlements, this study indicates that it is the availability of services and not land allocation that triggers actual development of residential housing. Thus, service provision determines the pace of change in short and medium city spatial patterns. This implies that in the context of public resource deficiency and self-help housing, strategic investments in basic services such as electricity connection, public transport and portable water is the way to influence actual city development pattern rather than providing plots.     

北京市住房价格和租金的空间分异与相互关系

当前中国住房销售市场、住房租赁市场发展不平衡,研究住房价格、租金的空间分异与相互关系,对建立“租售并举”的住房制度具有重要参考价值。利用2016年北京市各住宅小区的住房价格、租金数据,及2006—2016年北京市逐月住房销售价格指数、住房租赁价格指数,从时空尺度剖析了住房价格、租金的空间分异与相互关系,并剖析了背后的差异机制。结果表明：① 北京市住房价格和租金的空间格局均呈多中心圈层递减结构,且南北差异明显,但租金的空间分异程度弱于住房价格。② 住房价格具有中等程度的空间相关性,受政策等随机性因素影响相对较大,而租金具有强烈的空间相关性,受区位交通等确定性因素影响相对较大。③ 住房价格和租金的价格剖面线并不相同,住房价格易受学区、大型公园等的影响,而租金更易受就业所在地、建筑年龄等的影响。售租比呈混乱斑驳、相对均质的扁平化分布特征,且小区越高档,售租比越高。④ 北京市住房销售市场和住房租赁市场基本相对独立发展,更符合双重市场的特征。产生上述差异的主要原因在于住房销售市场和住房租赁市场的市场特征、服务人群以及市场发育程度不同。     

Heterolocalism,Networks of Ethnicity,and Refugee Communities in the Pacific Northwest: The Portland Story*

Geographic studies of refugee issues have emerged as salient topics of inquiry in the past decade. This spatial analysis of the migration experiences and heterolocal settlement patterns of refugees in an increasingly diverse part of the Pacific Northwest focuses on a place that the Atlantic Monthly recently called the last Caucasian bastion in the United States. Perceived as a region better known for its dense forests, progressive environmental policies, and rural ambience, the Portland metropolitan area and its hinterland in the Willamette Valley now resonate with ethnic and racial diversity. This article analyzes the spatial patterns and related networks of the three largest refugee groups in the region. Findings indicate that an overlapping and interrelated set of political, social, cultural, and economic networks are the most important factors in determining refugee residential patterns.     

从市区到市郊:二战后联邦政府主导下的美国郊区化运动

二战后,为解决严重的住房短缺问题,美国联邦政府一方面继续鼓励发展郊区住宅,如为退伍军人制定优惠贷款政策、修建州际高速公路,另一方面发起了城市更新运动,试图通过拆除城市中心衰败社区来改善居住环境,为城市中心的发展注入新的活力。然而,这些政策在推动郊区化的同时,也加剧了城市中心的衰落。这些政策的实施,既塑造了战后美国城市面貌,也对诸如城市暴乱、社会分化等问题负有责任。     

Effect of land prices on the spatial differentiation of housing prices: Evidence from cross-county analyses in China

This study analyzes the spatial patterns and driving forces of housing prices in China using a 2,872-county dataset of housing prices in 2014. Multiple theoretical perspectives on housing demand, supply, and market, are combined to establish a housing price model to explore the impact of land prices on housing prices. The relative impacts of land prices on housing prices at different administrative levels are then analyzed using the geographical detector technique. Finally, the influencing mechanism of land prices on housing prices is discussed. The main conclusions are as follows. (1) Housing prices have a pyramid- ranked distribution in China, where higher housing prices are linked to smaller urban populations. (2) Land prices are the primary driver of housing prices, and their impacts on housing prices vary over different administrative levels. To be specific, the effect of land prices is the strongest in the urban districts of provincial capital cities. (3) The internal influence mechanisms for land prices driving housing prices are: topographic factors, urban construction level, the agglomeration degree of high-quality public service resources, and the tertiary industrial development level. The urban land supply plan (supply policies) is the intrinsic driver that determines land prices in cities; through supply and demand, cost, and market mechanisms, land prices then impact housing prices.     

开发区居住空间特征及其形成机制——对北京经济技术开发区的调查

利用北京经济技术开发区的第一手问卷调查数据,研究开发区居住空间特征及其形成机制。研究表明：开发区居住人口收入和受教育程度相对较高,外来人口已成为开发区后期居住人口增长的主要动力来源;开发区的住房类型构成呈现多样化特点,政策和住房户型原因是影响住宅分化的重要因素;开发区在收入和社会阶层方面存在居住分化现象,具体表现为高收入和低社会阶层两级分化的空间隔离;作为新兴的郊区社区,开发区居民维权意识强烈,但社区联系较弱;上班通勤距离仍是影响居民居住地选择的最重要因素,改善居住环境、对优质教育资源的追求也是极重要的因素。最后,从居民、开发商、地方政府、企业、母城及周边区域等多元主体共同作用的角度探讨了开发区居住空间的形成机制。当前,国内开发区大多面临从“产业功能地域”向综合型的“城市化功能地域”转型,但开发区既是“产业集聚区”又被作为“卧城”的复杂状况,也带来其居住空间特征及形成机制的复杂性。研究成果对于丰富城市居住空间理论有重要意义。

长三角一体化区域城市房价空间分异的模式与效应

城市住房制度市场化改革以来,中国城市房价整体快速上涨,区域房价分异加剧。区域内部房价空间分异是城市发展差距的综合反映,即城市资源要素综合配置能力差异的物化表达。基于中国房价行情平台提供的2008—2018年地级城市和区县尺度城市房价数据,分析长三角一体化区域房价增长与分异过程,发现区域整体房价呈现快速上涨、相对平稳和再度快速上涨3个阶段,区域房价差异随房价上涨而扩大,上海、杭州和南京等城市房价增长更快,浙江、苏南地区与安徽、苏北地区的房价差距拉大。根据房价增长、城市等级与区位特征,将长三角327个区县划分为核心城市城区、中心城市城区、发达城市城区、其他城市城区、核心圈层县市和外围地区县市6种类型,提出一体化区域城市房价表现为整体上涨相对更快、不同类型区县间差异拉大、同类区县间存在“俱乐部收敛”等增长与分异模式。区域城市房价快速上涨与过度分异,驱使高端产业、人口等资源要素向少数“超级明星城市”集聚,加剧区域不平衡,不利于长三角地区实现更高质量一体化发展。     

乌鲁木齐市职住空间组织特征及影响因素

本文借助职住分离指数分析法从宏观层面分析了乌鲁木齐市辖区的职住空间匹配状况,利用问卷调查数据,从微观角度分析了不同类型居住区居民的通勤距离和通勤时间。研究发现：职住空间分离是乌鲁木齐城市空间结构的突出特征;全市职住空间不匹配程度较大,居住主导区的街道有35个,占街道总数的44.3%;就业主导区的街道有25个,占街道总数的31.65%;基本匹配区的街道仅有7个。居住区类型、居民受教育程度、职业类型、收入水平、住房形式等社会经济属性对其职住分离程度均有一定程度的影响;采用GWR模型定量分析了职住空间关系的影响因素,认为学历构成、住房产权性质、职业类型、流动人口以及住房面积是影响乌鲁木齐市职住空间关系的主要因素。     

THE EMERGENCE OF AFFLUENCE IN BEIJING: RESIDENTIAL SOCIAL STRATIFICATION IN CHINA'S CAPITAL CITY

Since 1987, the Chinese government has begun to liberalize its approach to land markets, allowing for the development of commercial residential housing and sparking greater distinctions in housing quality. At the same time, there have been growing income differentials among Beijing's residents. This paper discusses how Beijing's new urban affluent have begun to take advantage of greater housing choices. It reports on a survey conducted in 1997 that uncovers the occupational characteristics, consumption patterns, housing characteristics, and residential locations of affluent residents. The results indicate that Beijing's new urban affluent are beginning to share some of the consumption features of middle-class Westerners. At the same time, social segregation is still nascent in Beijing. There is now only a sprinkling of affluent neighborhoods in the city, and a slight majority of wealthier respondents continue to live in public housing. Moreover, few are able to afford detached single-family housing or a private automobile. The continuation of current trends could both deepen and broaden social segregation in Beijing, as class divisions come to be manifested in separate neighborhoods.

广州租赁住房的空间分布格局及其成因

采用开放数据,并借助K-means聚类等空间计量方法,解析广州租赁住房空间的格局特征,结果发现：1）租赁住房空间与商品住房空间在中心城区具有明显的东西分离的分布特征,同时租赁住房空间沿交通线分布的趋势更为明显,并在中心城区外围形成几处集中分布的地区;2）广州租赁住房空间分为核心租赁地区、核心自住地区、次级租赁地区、外围租赁地区、低容量自住地区和其他地区6种类型;3）投资性购房热潮、城市发展战略导向与轨道交通建设、郊区化与同城化的共同影响促成了广州租赁住房的空间分布格局。
