基于主成分分析法对保障房的商业设施配置研究——以武汉市为例

保障房性住房政策极大改善了中低收入阶层住房难问题,其商业设施配置对保障对象生活有重要影响。为了研究武汉市保障性住房商业设施配置,本文选择武汉市五处保障房商业设施,调查了影响保障对象生活的商业设施业种,通过主成分分析法,将保障房商业设施配置中的多类业种综合成为三个主成分。并提出了在保障性住房商业设施规划及管理中的一些建议,这将为保障房公共设施配置提供更具合理性和科学性的决策依据。     

房建工程中屋面渗漏水防治技术

西安烟草公司办公楼屋面多处渗水,处理方案是变上人屋面为不上人屋面,在已铺地砖屋面上再做了一层4mm厚sbs防水层,才保证屋面不再渗水。为避免再出现类似问题,本文从中学习并总结了渗漏的原因分析及预防措施。     

Incomplete privatization of public rental housing in Hong Kong

The delineation of the land occupied by Public Rental Housing (PRH) is a contentious issue in worldwide debates over PRH privatization. Heated arguments hold that governments should retain the occupied land for mitigating inequalities that privatization might provoke. Dual-role policies arise concerning both efficiency and equality. This research seeks to decode actual consequences of such policies based on their implementation in Hong Kong, with a specific focus on the Tenants Purchase Scheme (TPS). Intended to enliven PRH within needy families, the TPS policy instead resulted in dormant resale of privatized PRH with adverse effects on target groups. Hypotheses on how the TPS policy has affected housing resale are developed based on property rights and searching theories and tested against empirical data. This research offers a theoretical basis for exploring solutions to the unanticipated aftermath of Hong Kong’s PRH privatization and provides information for other governments on implications of privatization strategies.     

‘Stop Being a Tourist!’ New Dynamics of Urban Tourism in Berlin‐Kreuzberg

Berlin is witnessing a massive tourism boom, and parts of it can be described as ‘new urban tourism’, which shows a preference for off the beaten track areas and ‘authentic’ experiences of the city. This form of tourism seems especially salient in Kreuzberg. It is here that an openly articulated critique of tourism attracted national attention in 2011 and has not ceased to do so since. This article aims to better understand the conflictive potential of (new urban) tourism in Kreuzberg. We argue that the readily expressed negative attitudes against tourists and the easily accepted link between tourism and gentrification have to be explained against the backdrop of certain housing‐market dynamics. Rising rents and a diminution in the number of flats available for rent are fuelling fears of gentrification in Kreuzberg, while the interest shown in new urban tourism and the comparatively low‐priced real‐estate market in Berlin result in a growing number of holiday flats. Although adding only slightly to the tightening of the housing market, holiday flats render complex processes of neighborhood change visible and further sustain an already prevalent tourism critique.     

短期影响中国商品房房价因素的计量分析--基于31个省市的横截面数据

房价问题是影响国计民生的重要问题之一，分析房价的影响因素具有重要的现实意义。收集2012年北京、天津等31个省市相关指标的横截面数据，尝试在三种不同情况下用经典线性模型进行逐步回归拟合数据，再对不同模型进行比较，从而选出最优模型。最后，通过最优模型分析得出人均可支配收入与失业率是短期内影响中国商品房房价上涨的主要因素。     

House price determinants in Athens: a spatial econometric approach

In this paper, we try to identify the price determinants in the biggest real estate market of Greece, the metropolitan area of Athens. For that purpose, various spatial econometric models are used to explore their prediction ability and we are displaying the variations in property prices for the wider area of Athens. These models have been compared based on different criteria such as model fit, the Akaike information criterion and variance of the residuals. Our results indicate that, in our case, the spatial general model is the most appropriate simultaneous autoregressive model when dealing with spatially autocorrelated prices of housing properties data, in terms of our selection criteria.

‘Swift Rail’—funding local rail transit through smarter growth

Many medium-size cities suffer from severe traffic congestion and poor accessibility, limiting their potential to improve their economy, environment, and social equity. These problems could be addressed by creating high-quality transit linking such cities with suburban and other catchment areas through use of existing rail lines and abandoned former railway alignments. This concept, termed ‘Swift Rail’, would call for an innovative approach to local railway and transport development.     

Housing Allowance and the Rent of Low‐income Households

This paper analyses the effect of a housing allowance programme on the rent paid by assisted low‐income households. The data consist of 12,000 rental households in the free‐market and municipal sectors. The effect is estimated using the programme reform of 2002 as an instrument. The reform increased the allowance of the assisted households depending on housing characteristics, but it had little effect on the eligibility. Results suggest that in the private sector, one additional euro of allowance increases the rent of claimants by 60–70 cents. The effect is zero in the municipal sector, as rents are tied to the housing costs.     

When was the U.S. housing downturn predictable? A comparison of univariate forecasting methods

This paper uses three classes of univariate time series techniques (ARIMA type models, switching regression models, and state-space/structural time series models) to forecast, on an ex post basis, the downturn in U.S. housing prices starting around 2006. The performance of the techniques is compared within each class and across classes by out-of-sample forecasts for a number of different forecast points prior to and during the downturn. Most forecasting models are able to predict a downturn in future home prices by mid 2006. Some state-space models can predict an impending downturn as early as June 2005. State-space/structural time series models tend to produce the most accurate forecasts, although they are not necessarily the models with the best in-sample fit.
