农村宅基地使用权制度面临的问题及对策

我国以"一户一宅"为基本特征的农村宅基地使用权制度,为广大农民不断改善居住条件,维护"住有所居"基本权利提供了保障.但是,在经济社会背景发生了巨大变化的条件下,农村宅基地使用权制度的一些缺陷和不适应性开始更多显现,其中,较突出的是不少地方农村宅基地使用很难确保公平和达到集约节约利用的要求.论文在对部分地方进行的农村宅基地使用权制度改革的实践和探索进行评析的基础上,提出了一些解决当前存在矛盾与问题的建议.     

Developing a House Price Index for The Netherlands: A Practical Application of Weighted Repeat Sales

This paper describes the development of a house price index that has been introduced in May 2005 in The Netherlands. This monthly index, called Woningwaarde Index Kadaster (House Price Index Kadaster), is designed to detect changes in the price of the overall stock of owner-occupied homes. Fifty-five indices are calculated: one overall index, four regional indices, 12 provincial indices and 38 indices based on combinations of region/province and dwelling type. We used Case and Shiller’s geometric Weighted Repeat Sales Model to calculate monthly house price indices. We used recorded data on the sales of over 500,000 owner-occupied homes in The Netherlands, all representing repeat sales between January 1993 and December 2006. The accuracy of the index was determined using the 95% confidence interval. We observed that accuracy might become a problem in smaller sub samples. Revision volatility was explored by comparing the index values computed from all available data until December 2005 with the index values computed from the data available until December 2006. Our analysis showed that revision volatility does not seem to be a major problem to the index. We also explored heteroskedasticity in the Repeat Sales method but did not find conclusive evidence for the proposed heteroskedasticity. Given our target (a geometric mean index value) and the characteristics of the dataset (very large but without property characteristics) the Repeat Sales Method seems to be adequate for calculating a house price index for The Netherlands.

房价波动、金融稳定与最优宏观审慎政策

本文通过构建包含家庭住房抵押借款摩擦和银行贷款摩擦的动态随机一般均衡模型,重点考察了异质性冲击下房价波动对金融稳定的影响。研究发现,房价上涨会导致银行风险溢价及杠杆率显著上升,进而加剧金融体系的内在不稳定。为降低房价波动及维护金融稳定,选取两类宏观审慎政策工具进行逆周期调控实验,结果表明,在住房需求冲击下,金融管理部门应选取贷款价值比政策,且应对房贷积极调控,而对房价进行中性调控。在最终产品部门生产率冲击、房地产部门生产率冲击及跨期偏好冲击下,应选取资本充足率政策,但对房贷和房价调控力度的把握则存在差异。本研究为厘清房价波动对金融稳定的动态传导机制,以及金融管理部门如何选取宏观审慎政策工具以稳定房价并降低系统性金融风险提供了启示。     

Unplanned rural living and its policy implications: Some findings from Bundaberg,Australia

Research conducted in the Bundaberg Region in north-eastern Australia sought to explain the pattern of unplanned rural living and to assess whether its impacts are adverse enough to warrant land use policy change. It found there was limited conversion of suitable sugarcane land to ‘unplanned’ rural living during the 1980–2000 period. Parcels converted to unplanned rural living during this period were, on average, much smaller, had lower agricultural production potential, and were situated in more undulating and forested landscapes further from Bundaberg than parcels that remained in sugarcane production.     

货币政策背景下房价的变动关系研究

本文在货币政策传导理论的基础上,通过向量误差修正模型(VECM)实证分析了房价在货币政策传导过程中的作用。通过分析可知,房价在货币政策传导过程中起到了一定的作用,房价渠道的传导效率整体而言比较高,由此而知货币政策和房价之间存在着一定程度的关系。     

高房价是否导致了区域高技能人力资本流出?

我国正处于由人口大国向人力资本强国转型的关键阶段,高技能人才资源已成为当今区域经济社会发展的第一资源;与此同时,我国已经历了一段房价全面上涨的时期,由房价高速上涨所导致的人才流出问题引起政府与公众的广泛关注。在此背景下,本文通过对大学生就业地选择的关注,考察了高房价对地区高技能人力资本流出的影响。本文的结果稳健地表明,高房价显著地提高了大学毕业生离开本地就业的概率;根据本文的估计,在2010年至2015年期间,房价的上升至少增加了区域高技能人才流出21.5%;特别地,房价的挤出作用对于较弱家庭背景的学生以及非一线城市更为严重,此外,高房价也影响了大学毕业生的职业选择。本文的研究结果指出了中国高房价可能影响长期经济社会发展的一个新的重要渠道;同时,通过对房价的关注,为地区与国家减少高技能人才流出,实现经济发展由要素驱动向创新驱动转变提供了新的启示。     

A fuzzy group decision-making approach in quality function deployment

Quality function deployment (QFD) is comprised of two major group decision-making processes. One is to collect the customer requirements from a group of customers, whereas the other is to determine the relationship between customer requirements and technical measures by a cross-functional team. Generally, different and/or even subjective opinions are quite often in a group decision-making process due to the limitations of experience and impreciseness. Obviously, the importance of each customer requirement and the relationship between customer requirements and technical measures are determined by a group of people with imprecision and vagueness. Under such circumstances, a fuzzy group decision-making approach can be applied in QFD to deal with a group decision-making process when the information is imprecise and fuzzy. Moreover, an example is provided as well as the computational steps to show this fuzzy group decision-making approach can be effectively used in QFD to make decisions with imprecision and vagueness.     

基于租赁价格的房地产价格泡沫测度研究--以广州市房地产价格数据为例

在对房地产基础价值进行界定的基础上,提出了基于房地产租赁价格并考虑通胀因素的房地产价格泡沫测度方法。利用广州市2001-2013年的相关数据,对房地产价格泡沫程度进行了分析,并提出了相应的警戒标准,进而得出结论：以广州市为代表的一线城市的房地产价格尚未达到30%的泡沫警戒线,房价涨跌幅度仍属市场机制调节的正常范围,因而没有必要采取非市场调节手段干预房价的正常波动。
