Sharing of Encrypted Lock Keys in the Blockchain-Based Renting House System from Time- and Identity-Based Proxy Reencryption

To design an efficient protocol for sharing the encrypted lock keys in the renting house system,we introduce a new notion called time-and identitybased proxy reencryption(TIPRE)and the blockchain platform.Our CPA secure TIPRE scheme is constructed from Green et al.’s identity-based proxy reencryption scheme by adding the time property.In every time period,a time stamp authority generates a public key embedded with the current time stamp for each user.In our protocol for the renting house system,the TIPRE scheme is the primary building block,and the blockchain platform serves instead of a trusted third party,such as a real estate agency between landlords and tenants.The TIPRE scheme allows the landlord to change the lock key at each time period for safety.The blockchain platform allows the landlords and tenants to directly interact,and all of the interactions are recorded in the blockchain database to provide the desired security requirements,such as nonrepudiation and unforgeability.Finally,we provide the secure analysis of our protocol and test its performance by implementing it in the MacBook Pro and the Intel Edison development platforms.

Spatial Monetary Economic Growth with Housing and Residential Distribution over the Urban Area

This study introduces space, transportation, and money into an economic growth model. Growth theory neglects the importance of transportation on economic growth and transportation economics fails to properly explain how changes in transportation conditions (such as technological improvement, infrastructure investment, and oil prices) affect long-term economic growth. By proposing a growth model with transportations, we try to explain effects of transportation on economic growth. Our model describes dynamic interactions among capital accumulation, travel time, housing, residential distribution, amenity, and endogenous time distribution among work, travel, and leisure. The study examines effects of inflation policy, transportation conditions, and other conditions on long-term economic growth and economic geography. The paper demonstrates a way to integrating some important models in the literature in economic growth theory, urban economics, and transportation research so that the significance of transportation systems upon economies can be properly analyzed.

Research on public housing based on the utilities of living

This paper applies the residence utility principles to the study of public housing rent and regards that the average utility of a household determines the public housing rent level. It also suggests that the government use multi-level public housing rent to substitute for single-level in order to make the policies for public housing rent more just, equitable and effective.

Development of Online Based Smart House Renting Web Application

The house rental issue is one of the elemental parts of society. Nowadays, it is extremely difficult to find suitable accommodation in city areas if people search for it physically. On the other hand, the land owner also needs to rent the house. It can be difficult to find tenants just to hang a lease sign on a building, and as a result, they lose money. An online common platform can play a vital role in this case. The purpose of the study is to develop a common web-based online platform for both tenants and house owners so that both tenants and landowners will mutually benefit from the system. This paper presents the development of web applications for the people of Bangladesh where both house owners and tenants can register and tenants can have houses for rent via sophisticated contact with the house owner. In this paper, a common online-based smart house rental web application has been developed both for tenants and for house owners. This web application is very user-friendly, efficient and it has got many unique features that are not offered by other currently available house rental websites here in Bangladesh. Tenants can register using their phone number, store information about their identity, search for available houses, send messages to house owners, and choose a suitable house using developed web applications. House owners can also register for the system, which will manually verify and authenticate the knowledge provided by the house owner can view a tenant’s information history whenever a tenant makes contact through text and supply house-related information accordingly. The proposed online smart house system has been tested and validated. It works very efficiently with many features. The application provided faster and improved opportunities to get houses, as well as ensuring the availability of houses for rent in the greatest number of areas. The system will help to spread trustworthy services nationwide and supply users with the chance to speak and improve the house rent in Bangladesh. Because it has many smart features, this developed online smart house rental web application will make it very easy for tenants to find a house to rent. House owners, on the other hand, can easily rent out their properties.

Rental Location Choice Characteristics and Tendencies of Migrants in Guangzhou,China

The inner-urban residential location choice is a topic of continuing interest in urban geography.However,not much research has been done on migrants’rental location choices.Based on data from a questionnaire completed by 276 migrant renters in Guangzhou,this paper analyzes the demographics and social class characteristics of migrants,and the condition and location of housing preferred by this population.The results show that the migrants in Guangzhou mainly rent in the Center Business District(CBD)area(Tianhe District)and Huangpu,Panyu and Haizhu districts.The main reason for this choice of location choices is the houses’convenience to their workplaces.A second reason is that nearby subways make travel convenient,for consumption and daily life,for children to go to school,and for access to large shopping centers/malls.

构建租购并举的退役军人住房保障体系研究

适宜的居住环境对于保障和维护退役军人合法权益、促进社会稳定等具有重要意义。在新时代背景下,退役军人住房保障如何既满足国防和军队建设需要、又不超越基本国情是亟待破解的重要命题。本文在辨析国内外退役军人社会保障的理论基础之上,从历史制度主义视角梳理了我国退役军人住房保障政策演进,分析了现有政策的主要特征与关键问题,最终提出了构建租购并举的退役军人住房保障体系的政策建议。研究对于推动广大退役军人“住有所居”与“住有宜居”、构建“普惠与优待”叠加的退役军人政策制度体系具有启示意义。

农户城镇购房会提高宅基地有偿退出意愿吗?

盘活农村闲置土地资源,对发展乡村产业和持续提高农民收入具有重要意义。文章以江西省A区434户农户为样本进行实证研究,结果发现:农户在城镇购房会提高其宅基地有偿退出意愿;不同地域的农户宅基地退出意愿存在差异,在城中村或者城市郊区的农户,宅基地有偿退出意愿弱于非城中村或者城市郊区农户;存在受教育水平中介效应的影响,农户受教育水平提高会弱化城镇购房对宅基地有偿退出的影响。为提高农户宅基地有偿退出意愿,提升宅基地配置效率,要加强对宅基地有偿退出政策的解读与宣传,增加退出宅基地农户在城镇购房时的补贴或优惠,加大对城中村或城市郊区农村的改造,进一步完善社会保障体系。

房地产信贷与住房可支付性

本文使用2010—2022年中国135个城市房地产信贷、房价、房租以及家庭收入与消费数据,考察房地产信贷对住房可支付性影响。实证研究发现,城市房地产开发贷款占比越高,城市房价收入比越低;城市住房抵押贷款占比越高,城市房价收入比与房租收入比越高;房地产信贷对房价可支付性的影响大于房租可支付性;房地产开发贷款提高城市中等收入者住房可支付性,但住房抵押贷款降低城市中等收入者住房可支付性。因此,住房信贷政策应主要解决城市中等收入者房价可支付问题而非房租可支付问题。

房企破产中购房合同的处理方式

购房合同的处理无疑是房企破产的焦点之一。从系统性风险和法治化双重视角看,管理人原则上应当选择继续履行现房合同并认可已支付房款的优先权地位和对房企违约金的劣后债权地位;从房屋续建可能产生的价值提升以及消费者住房生存权益的保障角度看,管理人原则上也应当选择继续履行期房合同。与普通待履行合同的处置模式不同,购房合同的处置应转变为购房者的多层次自决:基于债务人追加担保及共益债保障的障碍,购房优先权人有权逐一决定是否接受现金清偿或是等待交房,且全体购房债权人基于对重整风险的分摊和自身权益的让步,均有权对重整计划、续建方案等事项进行表决,并根据其付出的时间与金钱成本分享房企继续履行购房合同的成果。在其他融资途径均行不通的情况下,可以由选择交房的购房者出资续建,且其出资额形成共益债务。同时还应充分利用数理思维来维护购房者之间的同质性及相应的权利救济。

论借名购房纠纷房屋物权的归属

司法实践中经常遇见所谓借名购房问题,这种房产物权名实不符的现象给相关司法裁判带来困惑,而《中华人民共和国民法典》(以下简称《民法典》)以及相关的司法解释中均没有对此类行为作出明确规定,各地法院在审理过程中的处理结果也不尽相同。对此,司法裁判应从意思自治的民法理念出发,结合《民法典》的基本法理及相关司法解释精神,在对借名购房纠纷中房屋物权归属进行系统法理分析基础上作出妥当处理。

限购政策与城市房价溢出效应——基于70个大中城市准自然实验的研究

基于2015年1月至2022年3月全国70个大中城市的房价数据,本文考察了第二轮限购对城市房价溢出效应的影响。研究结果表明,限购政策有助于促进城际间的房价溢出效应。异质性分析显示,沿海地区、大规模城市出台的限购政策所引致的房价溢出效应高于内陆地区、小规模城市,而有社保及个税缴纳证明要求以及针对全域范围内的限购政策更能引发城市房价外溢。拓展性分析表明,限购政策能够通过降低房地产市场关注度和房产交易量影响城市间的房价溢出效应。本研究对优化地方政府的房市调控政策具有一定的借鉴意义。

空间差异视角下的无房流动人口购房困难

存在购房困难是广大无房流动人口在城市安居的严峻阻力。基于全国流动人口动态监测调查数据,研究了无房流动人口购房困难的空间格局和影响因素。研究发现,无购房困难的流动人口主要集聚在辽东、山东半岛和两广地区,有购房困难的流动人口主要集聚在陕甘宁蒙鄂等省。城市更高的公共服务水平激发了流动人口的购房困难,而发达的经济水平则缓解了购房困难。购房和租房负担的加重使流动人口更易感到购房困难。农业户口、来自省内、有长居意愿、就业身份不稳定、无社保、租住私房或公租房、举家迁移的壮年已婚多子女流动人口更易有购房困难。根据流动人口所在城市住房成本的不同,上述因素的作用存在城市间差异,例如在较高房价城市,高学历和有社保均未能减弱无房流动人口的购房困难。研究对推进配售型保障性住房建设和激励住房市场需求有一定借鉴意义。

2024年中国城镇居民购房意愿调查报告

本报告基于清华大学恒隆房地产研究中心、抖音集团房产业务平台旗下幸福里研究院和《中国房地产金融》杂志联合发起的“2024年中国城镇居民购房意愿”大样本问卷调查数据,围绕居民住房现状、购房意愿和购房偏好三方面进行深入分析。调查针对年龄为18~60岁、当前位置处于选定城市城区范围的抖音用户随机发放,共回收有效问卷5085份。结果显示:(1)受访城镇居民居住水平整体良好,住房自有化率较高,对居住现状较为满意,但一线城市居民和租房群体的居住满意度仍有较大提升空间;相当部分受访者已得到各类保障性住房政策支持,对居住满意度提升作用明显;(2)15%的受访者在未来一年内有购房意向,其中高收入群体的购房意愿更强烈;改善住房在各能级城市均已成为首要购房目的,同时一线城市居民与中低收入群体中仍存在较大比例的首次置业需求;增强首付款支付能力与提振经济信心是提升居民购房意愿的关键着力点,同时租购观念发生转变,已成为购房意愿的重要影响因素;(3)周边配套、小区环境和户型是否合理是拟购房者选择住房时考虑的前三大因素;多数拟购房者对新房和二手房没有明确偏好;线下售楼处和中介门店仍是拟购房者获取房源信息的最主要渠道,线上渠道中社交媒体的作用已超越经纪网站。此外,本报告还对潜在首次置业人群和潜在改善性需求人群两类重点人群进行了专题分析。

论借名购房中的合同主体与物权归属

借名购房存在借名人、出名人、相对人三方主体,确定房屋所有权归属涉及三方利益平衡。欲明确借名购房中的物权变动与归属,前提在于精准厘定房屋买卖合同双方当事人。依据不同解释路径,虽然买受人的确定存在多种阐释可能,但原则上将之界定为出名人,无疑将使所有权转移为最贴合《中华人民共和国民法典》的现有物权变动规则。在明晰借名人的法律地位时,须严格贯彻不动产登记簿的外观主义,摒弃所谓事实物权、物权期待权理论。在处理涉及借名人的保护问题时,应综合考虑借名人的生存权利等其他相关价值因素,并将这些因素在执行异议之诉程序中作为特殊情况进行综合考量。

福利体制视域下德国住房保障政策研究

完善的住房保障政策,乃社会稳定之基石。当前,我国正处于社会转型的关键期,住房市场供需矛盾依然突出,一些地方房价大起大落。天下之大,民生为最,而住房问题始终是关系到社会民生的首要问题。德国住房保障政策历经起步奠基、发展完善与转型优化,其实物配租与货币补贴并重,体现了公平与效率的结合。然而,在实践中,德国住房保障政策亦面临诸多挑战,如资源分配不均、租金调控难、模式单一等问题。鉴于此,我国应汲取德国经验,但更需立足国情,创新举措。基于福利体制视域,提出我国应“盘活现有住房存量,优化资源配置;建立租金明镜制度,提升市场透明度;推行租购同权,切实维护租户权益;加快住房租赁立法,规范市场秩序;打破户籍壁垒,精准识别保障对象,确保政策惠及真正需要的人群”等建议。通过这些举措,以构建出更加公平、可持续的住房保障制度,让“居者有其屋”的美好愿景成为现实。

城镇住房保障政策研究——基于黄石保障房的调查分析

随着我国城镇化进程的持续推进,适应新增城镇人口的保障性住房需求与日俱增。基于湖北省黄石市保障房的调查研究,深入剖析了该市在保障性住房实践与创新策略方面的举措。文章采用住房可支付能力指标,对黄石市及其行政区的住房租赁情况进行了详尽的统计分析,并借助ARMA模型对租金收入比进行了实证研究。研究结果显示,黄石市在住房支付能力上存在显著的区域差异。基于此,文章提出了完善保障性住房政策、强化政府监管、推动多元化融资机制等策略,旨在为黄石市乃至全国保障性住房政策实践提供决策参考。

商品房限购政策的经济法理基础与实施问题研究

本文通过经济法的基本原理,深入分析了商品房限购政策的法理基础及其在实际实施中的问题。研究揭示了限购政策在遏制房价过快上涨、打击投机炒房行为以及保障居民基本住房需求方面的重要性。尽管限购政策在调控市场和遏制投机行为方面取得了一定成效,但也存在地方政府权力来源不明确、法律依据不足及政策灵活性和适应性不够等问题。为此,本文提出了规范限购令的制定程序、多方位定位房市投机行为及完善保障性住房政策的具体建议,以期为进一步优化限购政策提供理论支持和实践参考,促进房地产市场的健康稳定发展。

保障性租赁住房类型的TOD项目可负担性分析

近年来各城市陆续大力开展站点周边的土地开发,其中保障性租赁住房作为一种新形式的站点上盖开发的形式,能够起到改善民生的作用。为探究保租房类型的交通导向发展(transit-oriented development,TOD)开发项目的具体实施情况,本文对天津市佟楼地区的“H+T”可负担性进行了研究。首先,从建设情况上对保租房类型的TOD项目和普通TOD项目进行了对比,其次,计算了佟楼保租房类型TOD的“H+T”可负担性大小,然后调研居民主观感受,分别建立结构方程模型和中介模型,分析了保租房类型TOD项目的居住满意度的影响因素;房租价格高低、“H+T”可负担性对居民满意度的影响机理。结果表明,房租价格通过“H+T”可负担性影响居住满意度这一中介效应值为0.348,直接效应为0.170。最后,给出保障房TOD建设与运营的相关建议。

住房限购政策下房价波动研究——以武汉城市圈为例

为把握住房限购政策下房价波动方向和传导幅度,文中基于武汉城市圈月度房价数据,通过VAR模型探讨了住房限购政策下城市间房价的波纹效应。研究表明,住房限购政策的冲击是城市间房价变动的一个重要因素,“核心城市”房价受到政策冲击时,会因波纹效应影响城市圈其他城市房价,住房限购政策对房价的影响在短期内效果显著。
