基于WebGIS的基准房价信息发布系统设计

基准房价是指以宗地为单位、同种用地类型的房地产单位面积的市场特征价格，构建基准房价的目的在于全面、及时、定量、准确地披露房地产价格体系。基准房价的研究可以为政府制定政策性住房售价、租金标准、征地拆迁补偿标准、房地产税费征收等提供参考依据，同时也可以为普通民众的房地产消费提供价格指导。鉴于基准房价研究的重要意义，在总结国内外基准房价概念、内涵、特点及其信息发布相关理论和技术现状的基础上，设计实现了一个基于WebGIS技术基准房价信息发布系统，经过试运行，用户可以通过该系统快速准确地查询研究区域内的基准房价及其相对应的空间信息。     

The economics of property taxes and land values: The elasticity of supply of structures

Land values are explained by diminishing returns to a variable factor, structure, added to fixed land. The total cost minimizing structural density determined by land value, occurs where the marginal cost of increased density equals the average cost of structure plus land. Structural demand prices equal marginal costs in equilibrium determining land demands. A general equilibrium land price establishes the uses, prices and densities of structures. A simple method of calculating structure supply elasticity and the incidence and deadweight loss of property taxes is developed. Differing property tax rates are found to be efficient.     

房地产税改革与土地财政困局破解——基于对地方财政影响的情景分析

地方政府过度依赖土地出让收入是当前中国公共管理面临的重要难题。改革房地产税制并触发土地制度的连锁反应是破解中国土地治理困局的基本出路。通过预测不同改革方案下典型城市住房相关土地财政收入变化,评估房地产税替代土地出让（纯）收益成为地方支柱性收入源的前景。研究发现,如果合理设计覆盖城市存量和新增住房的房地产税,可在短期内保证地方土地财政收入的相对稳定,并在远期实现房地产税替代土地出让金成为地方财政支柱的目标,增强土地财政收入的可持续性。近期政府应改变“重流转、轻保有”的状况,将房地产税培育成为地方主体税种,远期应推进城乡一体化土地市场体系、土地出让制度和土地增值税制度联动改革,使地方土地财政收入从以一次性的土地出让纯收益为主向以持续的房产保有税、土地增值税等为主转变,促进政府土地管理本位职能回归,破解土地财政与政府治理困局。     

论我国现行土地制度对物业税的影响

本文基于土地所有权与土地使用权可以相对分离,土地使用权具有物权特性,土地使用权人享有相应期限内的土地收益权,对土地使用权课征不动产税可以弥补土地出让制度的缺陷,可以规范中央与地方的财政分配关系等方面的分析认为,虽然中外土地制度存在差异,但是中国土地公有制并不能成为开征不动产税的障碍。     

旁地产价格增长是否阻碍城镇化进程——基于我国31个省级单位面板数据的经验分析

通过对我国31个省级单位面板数据进行实证研究，发现从全国整体来看，房地产价格上涨对城镇化进程体现出正向促进作用，但是根据地区层级上的分析，在中西部地区房地产价格增长对城镇化具有显著的负向抑制作用。可见，现阶段房地产价格显然在阻碍城乡间劳动力要素流动方面扮演了重要角色。不断增长的房价增加了城镇化成本，对于农村劳动力转移起到阻碍作用。因此，为了保障新型城镇化的实现，必须通过土地、财政、金融等制度变革与其他市场化手段相结合，遏制房地产价格继续过快上涨，从而实现房地产市场与新型城镇化的协调发展。     

房地产市场调控，要坚持更要完善——“十年调控”问卷调查的启示和思考

通过对196份问卷的总结分析，得到对于未来房地产调控的许多启示：十年房地产调控是必要的；总体评价消极的依据是供求依然失衡，房价越来越高。调控成效不彰的原因有：对住房供求政策、调控配套政策评价消极，还认为财政税收压力是地方政府不积极的首要原因。大多数问卷建议：推动供求和房价基本稳定还是调控首要目的确立；房价合理上升的几个界限；房地产调节机制应该以市场调节为主、政府调节为辅；明确住房需求政策、住房供给政策、住房土地政策、经济手段、行政手段和税收手段改进的方向。     

Explaining regional variation in equilibrium real estate prices and income

We combine the real estate model of Potepan (1996) with the spatial equilibrium approach of Roback (1982) to prove the interdependency of housing prices, rental prices, building land prices and income via one simultaneous equilibrium analysis. Using unique cross-sectional data on the majority of German counties and cities for 2005, we estimate the equations in their structural and reduced form. The results show significantly positive interaction effects of income and real estate prices. Moreover, we can confirm model predictions concerning the majority of exogenous determinants. In particular, expectations about population development seem to be among the most important determinants of price and income disparities between regions in the long term.     

Impact of electronic road pricing on real estate prices in Singapore

Since 1998, Singapore has had an Electronic Road Pricing (ERP) system set up with a network of toll gantries to tax vehicles entering designated areas in the city center during peak hours. Using the congestion rate hike with effect from November 1, 2010 as an exogenous shock, we test the effects of the ERP rate hike on retail, office and residential real estate prices. The results show that the November 2010 congestion toll rate increases cause a 19% drop in retail real estate prices within the cordon ERP areas relative to retail real estate prices outside the cordon ERP areas. The results are statistically and economically significant. However, the toll rate hike has no significant impact private office and residential real estate within cordoned ERP areas. The robustness and falsification tests could not reject the negative effects associated with the toll rate hike on retail real estate prices.     

浅谈房地产项目土地增值税的纳税筹划

对于房地产行业来讲,在近年来的发展中,国家出台了相关宏观政策,对该行业进行了调整,所以房地产企业的发展受到了一定程度的影响,许多企业在发展过程中由过去的粗放式管理模式向精细化管理模式转变。房地产企业在盈利的过程中,需要向政府及相关土地部门缴纳土地增值税,这对于企业自身的盈利能力以及现金流会产生较大的影响,所以房地产企业针对土地增值税进行纳税筹划具有非常重要的意义。论文以土地增值税纳税筹划的积极意义为出发点,论述了纳税筹划工作的原则及方法。     

房地产税的价格效应——基于人口城镇化的区位粘性视角

本文从城镇化进程中人口流动的区位粘性这一全新视角,将房地产税负引起的价格效应与公共服务的区位偏好相结合。通过相关参数估计,以京津冀地区为例,模拟出同一税率下不同城镇化发展阶段的城市房地产价格走势差异。结果表明,北京和天津已经进入城镇化后期阶段,开征房地产税能够适度抑制房价,河北省这一作用则不明显。此外,本文还回答了人口城镇化、地方公共服务以及房地产市场的内在机制,并在此基础上探寻各地区开征房地产税的最佳时机。     

开征个人住房房地产税的政策效应分析——从土地节约集约使用的角度

近年来,我国房地产业飞速发展,但是房地产税收制度相对于市场变化,明显存在政策制定上的滞后性,无法有效地对该产业的资源优化配置作出良性引导。通过界定土地节约集约使用的衡量标准,简述我国房地产业土地开发利用现状;进而从促进土地节约集约的角度,对个人住房征收房地产税的政策效应作出分析,得出相应的结论。     

基于财产税征收的不动产价值评估——对北京市4个内城区的实证分析

通过对2006年北京市东城区、西城区、宣武区、崇文区4个行政区461个二手房交易有效数据的多元回归分析,建立了不动产价值批量评估模型,并对25个二手房交易价格与评估价格进行了比较.研究认为,可以通过建立健全不动产交易数据信息系统,对未来财产税征收为目的的不动产价值进行高效率、低成本的批量评估.建议对不动产市场交易不活跃的城镇,结合城镇土地定级估价成果和建筑物价值的成本法评估,合理确定基于财产税征收目的的不动产价值.     

土地增值税税收流失风险的防范机制研究——来自广东省汕头市地方税务局的征管经验

房地产税收流失风险是税务管理的重点和难点。在研究现行土地增值税征管模式的基本特征及存在问题的基础上,汕头市地方税务局引进风险管理机制,对土地增值税的管理由事后管理向事前和事中管理转变。探索出"前馈控税、项目管理、信息比对、模型构建"的土地增值税收流失的风险防范机制。并据此提出了一些政策建议。     

基于债务危机视角下的房价走势解析——来自深圳的证据

为了探讨债务危机视角下的房价走势,运用计量经济学方法构建时间序列模型,研究发现:1)债务危机实质是房地产危机,需要提高土地价格避免房地产危机和债务危机.2)地方政府、国企和商业银行主要通过增加地方债务规模、土地出让金、土地成交单位价格、房地产开发贷款和提高贷款利率差来增加房价.     

基于系统动力学的房产税政策仿真研究

为了科学、有效地分析房产税对房地产市场的调控作用,提高房地产政策的合理性与前瞻性,有必要建立商品住宅系统政策仿真模型,深入分析住宅系统内各因素之间的反馈关系。基于建立的住宅仿真模型,实现对房产税政策的模拟实验,得出房产税政策对住宅需求市场以及住宅价格的影响程度。本文以昆明市房地产市场作为研究样本,利用仿真系统进行了实证分析。实证结果表明,房产税对住宅增量有抑制作用,但短期内对住宅价格影响程度有限。     

Land Prices and Tax Policy: A Study of Fiscal Impacts

A bstract . Various tax measures are in use in efforts to control the level of land prices and to moderate changes in them. These are the site value, vacant land, increment value and transfer taxes. Analysis indicates that sufficiently heavy site value taxes can help stem the rise in land prices and that relatively heavy vacant land taxes can be used to encourage the development of certain urban land. Both instruments may bring forward the time of development. Both are perhaps the best tax tools for controlling speculation. Significant problems seem likely to attend the use of land value increment and transfer taxes applied at high rates. Non-tax alternative or complementary measures are also analyzed.     

利用税收政策调控房地产市场的对策思考

近年来，我国房地产业飞速发展，房价节节攀升，国家不断出台宏观政策来调控抑制房价，虽然取得一定成效，但仍然存在很多问题。加大税收杠杆的调节力度，通过税收政策的改革和创新来引导我国住房的理性消费势在必行。本文从税收角度分析了房价上涨的原因，对现行的税收政策提出了改革建议，以期稳定房价，促进房地产业的健康发展。     

浅析房产税实施存在的问题及发展建议

目前我国楼市价格一路猛涨,为了有效抑制继续上升的房价,我国政府在上海、重庆率先实施房产税试点办法。本文针对2011年年初上海、重庆两地对个人住房征收房产税试点的暂行办法进行分析对比,提出我国房产税实施存在的问题,并进一步提出合理的解决办法。     

1. The Role of Land Markets in Economic Crises

It is widely recognized that the economic crisis of 2009 was caused by unsound lending for real estate. Largely ignored, however, is that this contraction was easily predicted on the basis of a well-established pattern of land speculation, premature subdivision, and excessive building on marginal land that recurs approximately once every 18 years. Capital locked up in projects that are started during a land bubble is effectively lost during the downturn, leaving the nation without sufficient capital to finance ordinary business operations during the recovery period. The best instrument for avoiding this boom-bust cycle is the property tax and, more specifically, the portion that falls on land. We explore here the ways in which the property tax influences the intensity, timing, and location of development. We also examine why frequent and accurate assessment are essential to make the property tax an effective method of preventing speculative real estate bubbles.     

Financial intermediation and real estate prices impact on business cycles: A Bayesian analysis

How do financial intermediation and real estate prices impinge on the business cycle? I develop a two-sector stochastic general equilibrium model with financial intermediation and real estate collateral to assess the impact of financial conditions and land prices on aggregate fluctuations. I estimate the model with Bayesian methods using a novel data set that includes U.S. macro and financial variables during the period 1975–2010. The results from the estimated model show that financial conditions have a sizable effect on the variability of investment spending, while productivity shocks are the main source of consumption fluctuations. Specifically, on the macro side, (1) financial shocks explain about three quarters of investment spending variability and one third of the variance in hours worked. On the financial side, (2) financial shocks explain most of the variability in land prices, credit spread, and aggregate net worth of the financial sector. The model also accounts for observed unconditional moments of macro and financial variables. Our quantitative results are suggestive of the impact of diverse sources of financial instability, and as such relevant for macro prudential policy analysis.
