保障我国农民土地收益的制度分析

近年来，由于制度安排的缺陷，我国农地大量转非，农民利益受到损害，导致大量失地农民出现，危及粮食安全和社会稳定。当前，尽管中央对土地进行了严格管理，但是只是临时政策性的措施。要从根本上解决这些问题，必须从制度创新上寻求可行的途径。为此，本文通过对农民土地利益损失的制度原因分析，并对农地制度固化和创新的风险以及几种可供选择的制度创新方案比较后，认为渐进式的制度改革是符合我国的现实选择。     

区域产业结构调整与土地可持续利用关系研究

文章通过实证分析方式阐述了区域经济发展与土地利用相互关系，着重分析了我国非农产业发展的不同阶段耕地占用状况的变化，在此基础上，进一步分析了区域经济系统产业结构升级与用地结构的变迁关系，尤其是“十五”期间我国产业结构的进一步升级，将在一定程度上进一步带动农业用地的非农化，同时还可能会造成土地污染问题，据此作者认为我国产业经济的可持续发展必须以土地资源可持续利用为基础，并提出了推进我国可持续发展的战略实施的土地资源可持续利用政策体系。

我国土地征用制度探讨

国家为了公共利益的需要,可以依法对土地实行征用,但是这种征用必须符合公共利益、给予公平补偿、满足正当程序的要求。完善我国土地征用制度应该在这三个方面着手。

城市建设管理中环境问题的思考

可持续发展应该成为城市建筑设管理的重要战略，通过分析传统的城市建筑设管理观念，我们应该在更深层次上深化对城市管理与生态意识，环境规划之间关系的认识，从而达到城市管理现代化的目标。     

A Semiparametric Method for Valuing Residential Locations: Application to Automated Valuation

This paper is motivated by automated valuation systems, which would benefit from an ability to estimate spatial variation in location value. It develops theory for the local regression model (LRM), a semiparametric approach to estimating a location value surface. There are two parts to the LRM: (1) an ordinary least square (OLS) model to hold constant for interior square footage, land area, bathrooms, and other structural characteristics; and (2) a non-parametric smoother (local polynomial regression, LPR) which calculates location value as a function of latitude and longitude. Several methods are used to consistently estimate both parts of the model. The LRM was fit to geocoded hedonic sales data for six towns in the suburbs of Boston, MA. The estimates yield substantial, significant and plausible spatial patterns in location values. Using the LRM as an exploratory tool, local peaks and valleys in location value identified by the model are close to points identified by the tax assessor, and they are shown to add to the explanatory power of an OLS model. Out-of-sample MSE shows that the LRM with a first-degree polynomial (local linear smoothing) is somewhat better than polynomials of degree zero or degree two. Future applications might use degree zero (the well-known NW estimator) because this is available in popular commercial software. The optimized LRM reduces MSE from the OLS model by between 5 percent and 11 percent while adding information on statistically significant variations in location value.     

我国农村土地制度的产权经济分析

近年来我国农村发生了土地制度的深刻变革,变革的核心是土地产权制度的变迁。这种制度变迁在某种程度上具有帕累托改进的性质,但在某些方面还有待于发展和完善。我国农村土地产权制度建设的思路:以现行产权制度为基础,通过修订和完善,不断发挥现行产权制度的积极作用。     

Value relevance of proportionate consolidation versus the equity method: Evidence from Hong Kong

Whether proportionate consolidation (PC) or the equity method (EM) provides more informative financial statements is a controversial issue. This study uses data from listed companies in Hong Kong to investigate the value relevance of the EM compared with PC during 2005–2008 when the local word-for-word equivalent HKAS 31 offered the same options. The results of this study provide evidence that PC does not offer higher value relevance than the EM. PC’s horizontal aggregation of a portion of the operations, assets and liabilities of the jointly controlled entities with those of the venturer is less informative to investors than the EM’s vertical aggregation.     

The implications,challenges and benefits of a complexity-orientated Futures Studies

Complexity science is increasingly cited as an essential component of a Futures Studies (FS) capable of assisting with the wide-ranging and complex societal problems of the 21st century. Yet, the exact implications of complexity science for FS remain somewhat opaque. This paper explicitly sets out the challenges for FS that arise from six complexity science concepts: (1) irreversibility of time (2) path dependence 3) sensitivity to initial conditions (4) emergence and systemness (5) attractor states (6) complex causation. The discussion highlights the implications of these challenges for FS tools such as horizon scanning and weak signals, and sets out the benefits of overcoming the challenges to create an explicitly complexity-orientated FS. The discussion concludes with a set of questions summarising the challenge for FS from complexity science with the aim of stimulating a discussion as to how they can be met. The concluding remarks make some initial suggestions in this regard.
