论中西部农村土地承包经营权流转的制约因素与破解对策——以湖北、贵州两省的实证调研为依据

通过实证考察湖北、贵州两省近几年农村土地承包经营权流转的现状及对其成因的探析可以发现,中西部地区的农村要达致土地承包经营权规模化经营的理想状态,还有诸多制约因素有待克服。破解之道主要在于应构建有利于促进土地承包经营权流转的配套制度,营造有利于土地承包经营权流转的社会条件和经济环境。     

Governing Suburbia through regionalized land-use planning? Experiences from the Greater Frankfurt region

This paper explores the case of peripheral settlement growth in the Greater Frankfurt (Main) region within current debates on global suburbanization. Within Germany’s sophisticated spatial planning regime, Greater Frankfurt’s system of regionalized land-use planning marks an ambitious initiative to contain urban sprawl. Nonetheless, expansive peripheral settlement growth, and socio-spatial polarization remain distinct characteristics of the booming region. Analyzing state regulation vis-à-vis dynamics of capitalist urbanization and private authoritarianism, we decipher the complex governance arrangements producing this, at first sight, contradictory simultaneity. We uncover the rationales of local growth politics of autonomous municipalities and the region’s multiplied institutional fragmentation that undermine planning ambitions to contain suburban growth. We conclude by critically assessing the political economies of suburbanization in Greater Frankfurt and point to prospects for regional reform.     

Parking behaviour: Bundled parking and travel behavior in American cities

We investigate the relationship between bundled residential parking and travel behavior, with a particular focus on use of public transportation, and controlling for vehicle ownership. When the cost of parking is bundled into the price of housing, the time and stress of finding parking near home falls. These lower costs may lead households with bundled parking to drive more and use transit less than households without parking, even if both households own vehicles. To date this idea has been difficult to examine empirically. In this article we test this prediction using the public transportation module of the 2013 American Housing Survey. We confirm the association between bundled parking and travel. Households with bundled parking use transit less, spend more on gasoline, and—when they do take transit—are more likely to drive from their homes to the transit stop.     

Convergence between satellite information and farmers’ perception of drought in rangelands of North-West Patagonia,Argentina

Drought is a complex natural hazard with social and environmental implications. Satellite information is increasingly used to support decision-makers in preventing or coping with the negative impacts of drought. The integration of local and scientific knowledge to support drought monitoring is still far from being the main procedure in the development of drought monitoring and early warning systems. This study aimed at assessing the degree of convergence between satellite information on the effect of droughts on rangeland vegetation, from time series analysis, and farmers’ perception of drought in North-West Patagonia, Argentina. We characterised the scientific evidence of drought in terms of duration, spatial distribution, most severe years and recovery for the period 2000–2018 by identifying inter-annual NDVI changes. Farmers’ perceptions and experiences of drought were studied with open-ending interviews, with respect to occurrence, duration and recovery for that period. Satellite information matched farmers’ perception of drought at a regional scale, emphasising the value of remote sensing tools in supporting regional policy decision-making. However, farmers’ perceptions and recall of past drought impacts were more diverse than satellite information at a local level, highlighting the need for knowledge integration at finer scales.     

"十二五"时期我国出口依存度变动相关问题研究

我国出口依存度似高实不高,且存在明显的结构性不平衡."十二五"时期,我国出口增长仍面临明显的机遇,出口仍有可能获得快速增长,出口依存度仍有可能进一步提高.对于我国而言,不应追求出口依存度数字上的下降,而应抓住我国外需扩大的机遇,顺应我国出口增长的趋势,加快出口部门的结构性调整和出口质量的提高.具体而言,一方面要推动加工贸易转型升级,另一方面要提高一般贸易的发展水平.     

Awareness as a foundation for developing effective spatial data infrastructures

The development of an effective spatial data infrastructure (SDI) often occurs in a fragmented organizational environment requiring a high level of inter-organizational collaboration. Different organizations from various jurisdictions need to work together closely when agreeing on how they will jointly register, store, use and share data and how they will make their data available to the wider society. However, this collaboration is generally regarded as very difficult. For example people often resist data sharing across organizational boundaries due to loss of control, power and independency. Organizational issues are thus considered one of the fundamental constraints to inter-organizational sharing of spatial data.

农地流转改革的所有权基础：集体抑或国家？

农地流转改革始终无法回避中国集体所有制作为地权结构基础的发展走向论证问题。做实集体土地所有权的观点忽略了土地的权利属性前提、历史与逻辑前提和地权发展的价值前提,中国终将会以"土地国家所有+做实使用权+做虚所有权"的方式来回复土地的私权属性。在土地国家独占基础下,需要对发展权的权利设置和土地承包制的运行逻辑进行着重论证,由此来夯实土地流转改革的应然性地权构造基础。     

中国的房价与地价:理论、实证和政策分析

本文采用四象限模型、格兰杰因果检验和误差修正模型等分析方法,从理论、实证和政策等方面对中国房价与地价关系以及市场结构和政府供地方式的转变对二者关系的影响进行系统、深入地研究,并对进一步规范房地产市场秩序,理顺地价和房价形成机制等提出政策建议。研究结果表明,短期内房价决定地价,长期内二者相互影响。与协议出让方式相比,土地招拍挂出让通过促进土地市场的买方竞争、降低房地产增量市场的垄断性,在显化土地价格的同时,降低了地价对房价的影响程度。
