城镇化进程中县域地价评估体系建立研究

城镇地价是影响土地流转、推动城镇化进程的重要因素,现行体系下评估出的价格各自独立、缺乏可比性。文章通过建立研究区地价评估体系,将各自独立的城镇纳入一个系统进行比较、划分城镇等级、建立以城镇为单元的地价评估体系,以配合政府努力实现区域地价一体化、稳妥推进城镇化目标。

公共管理与公共服务用地基准地价评估探析

随着公共管理与公共服务用地有偿使用的逐步推广,把公服用地基准地价作为基本用途进行编制成为土地有偿使用的客观市场需求,2016年年底,政府将公服用地基准地价纳入基准地价体系中,但目前并没有关于公服用地基准地价评估的技术参考,文章提出了根据成本逼近法计算公服用地基准地价的思路和方法。

集体建设用地基准地价评估的若干问题探讨

我国在集体建设用地基准地价研究管理上,一直处于空白的状态。主要原因是我国建设用地的规划内容一直没有得到有效的开展。所以,为了适应当前土地交换运作模式,我国应该在集体建设用地基准地价评估内容的实践中结合试点工作的开展,制定相应的制度。文章针对集体建设用地基准地价评估问题进行了相应的探究,望得出的结论可以给工作人员的业务开展带来相应的帮助。     

城市基准地价结构分析

基准地价是作为政府对土地市场地价水平引导和管理的依据,其形成有着自身的一般规律和特点。文章采用比率指数法,通过对陕西省11个城市基准地价的比较分析,来研究陕西省各城市间基准地价的结构特点和规律,以期为基准地价的更新提供借鉴。

对上海房价居高不下的理性思考

房价具有一定的区域性特征,房价的居高不下必然会给区域经济健康持续发展带来许多隐患。必须找准影响区域房价的深层原因才能制定有效的调控措施平抑房价。影响房价的深层原因既有内部的也有外部的,地价及建筑安装成本是内部原因;经济因素、政策因素和价格预期是重要的外部因     

地方政府竞争、二元地租与产业发展

文章指出,现行的财税制度和政绩考核制度促使地方政府之间为了实现地区财税收入最大化和个人政绩最大化而竞争。为了吸引工业资本的进入,地方政府采取了低地租引资的方式,同时抬高商住用地的价格,从而形成了土地价格的＂二元＂化。这样,一方面阻碍了产业的梯度转移,延缓了东部比较优势的动态转化;另一方面,推动了畸高的房价,加剧了产业风险。文章呼吁改革政绩考核制度、完善财政税收体制和推进土地资源的市场化改革,以更好地引导产业发展。     

Regional Competition in China under the Price Distortion of Construction Land: A Study Based on a Two‐regime Spatial Durbin Model

This study examines regional competition in China by considering the spatial correlation and spillover effect of construction land price distortion using a two‐regime Spatial Durbin Model to investigate the patterns and trends of the competition between 285 cities in China from 2006 to 2015. The study finds: (i) price distortion of construction land is a common phenomenon but the distortion index generally shows a declining trend; (ii) regional competition through construction land price distortion shows a weakly intensified pattern, although the competition patterns in the four regions of China varied; and (iii) the intensity of competition between regions was lower during the 12th Five‐year Plan compared to the 11th Plan. The intensity of competition between cities was also lower inside than outside urban agglomerations. These results provide policy implications for remedying the price distortion of construction land and promoting regional coordinated development.     

工业用地价格是否影响企业进入:来自中国城市的微观证据

在土地供应市场化之后,工业用地价格迅速上升并开始成为制约中国制造业发展的重要因素。文章采用2003-2007年中国城市面板数据,考察了工业用地价格对企业进入的影响。研究证实,东部地区工业用地价格上涨的确抑制了新企业的进入,但这一关系在中西部地区并不明显。进一步研究显示,地价上涨对企业进入的抑制效应在非国有企业、土地依赖型行业以及低增加值行业中更加明显。     

土地出让收入的区域差异分析

近年来我国土地出让收入的区域差异明显,主要原因在于地区间经济发展水平不平衡、土地出让价格差异较大以及对土地供应缺乏有效控制。土地出让收入的区域差异加剧了区域间财政收入能力的横向失衡,也加大了中央政府均衡区域间财政能力的难度,应采取相应的政策措施加以解决。     

Agricultural land price and quality

Land quality can be expected to have important implications for productivity and so also for policy. Land quality is a factor influencing the price of land. Factors influencing land prices were therefore disaggregated on a regional basis. Land quality indices were constructed by considering only those factors directly affecting quality, and with significant statistical coefficients. Statistical regions were used as units of observation. Land quality was found to vary considerably. In some South African regions, land quality is comparable to that in the most arid regions of the world. The quality in certain small areas compares with above‐average land qualities in the world, but not with the best.     

农村经济制度变迁与农业增长因素的贡献度

基于1978～2005年省际面板数据,对我国农村经济制度变迁、地区差异与农业增长进行研究表明,制度变迁对我国改革开放后农业增长作用显著,土地产权制度、价格制度、财税制度变迁通过影响农民生产积极性和经济利益来影响农业增长。同时,各地区中影响农业增长的各种因素及其对农业增长的要素贡献度存在差异。可从加强农村经济制度创新入手,结合区域优势和资源优势,寻找制度创新和地区特色的结合点来促进农业稳步增长.缩小地区差异。     

土地供给、分配机制与地方财政风险防范

在快速城市化背景下,我国与土地相关的财政收入呈现超常规增长趋势,此现象引起学术界、政府部门和民众的广泛关注并成为争论的焦点。土地财政可持续的治理方式在于遏制土地低价供给的途径以缓解地方政府"卖地赚钱"的冲动,并通过建立合理的土地收益分配机制稳定地方政府的土地预期收益,同时辅之以政绩考核制度改革和政府财政风险防范机制的增强。     

What happens to land price when a rural construction land market legally opens in China? A spatiotemporal analysis of Nanhai district from 2010 to 2015

Urban and rural construction land markets in China, the two formerly separated markets, are beginning to be unified in some pilot areas. So far, but little is known about the associated land market development patterns and what factors influence land market price. In order to examine the impact of urban developers' access to legal rural construction land market on land price, we analyzed the spatiotemporal heterogeneity of price trends for the rural-urban land market in Nanhai district, Guangdong Province, between 2010 and 2015. We collected 2285 land transaction data during that span and mapped price contour lines for the rural-urban development land market in the whole district by using spatial interpolation techniques. Four hedonic price models, on rural and urban construction land respectively, were developed to measure the marginal effects of land attributes on price. Results from the analysis suggest that, temporally, the prices of rural-urban development land grew rapidly between 2010 and 2015. Spatially, prices spread along a gradient from east to west, and the prices in North Nanhai district were significantly higher than those in the south. The hedonic models also suggest that land use type, lot size, and various spatial characteristics impact rural and urban land prices. Overall, this research presented here contributes our understanding of the complex nature of establishing a unified land market in China.     

Property-Price Determinants in Indonesia

Price formation provides critical insights into the attributes of fledgling property markets in developing countries. This article investigates asking-price formation across the Indonesian archipelago, including previously unstudied regional property markets. We compile a rich micro dataset of asking prices for residential, commercial, and undeveloped land from a nationwide classifieds database. Through a hedonic price analysis we identify the impact of property and advertisement attributes on asking prices for each type of property, using spatial fixed effects to control for spatially correlated unobservable characteristics at the district and city levels. Results indicate that property characteristics, land ownership status, and advertising method are all statistically significant indicators of asking price. We find considerable heterogeneity in asking-price formation in residential, commercial, and undeveloped land, and identify key differences between urban and rural markets.
