大都市郊区小城镇的经济地域类型及其空间分异探析——以北京市为例

本文致力于探析京郊小城镇的经济地域类型及其发展的动力机制,综合运用了H.J.纳尔逊的城镇职能分类方法和区位商法,从三次产业的产值结构和从业结构出发,将京郊183个小城镇划分为四大类型。基于GIS的空间分析功能,进一步探讨了京郊四大类小城镇的空间分布规律和演变趋势,结果发现这四大类小城镇的核心—外围空间格局十分明显,有着各自不同的功能定位和演进机理。基于此,为不同类型的小城镇制定了不同的发展策略,以便为今后不同类型的小城镇开展分类规划指导提供科学依据。

Assessing the historical role of credit: Business cycles,financial crises and the legacy of Charles S. Peirce

This paper provides a historical overview of financial crises and their origins. The objective is to discuss a few of the modern statistical methods that can be used to evaluate predictors of these rare events. The problem involves the prediction of binary events, and therefore fits modern statistical learning, signal processing theory, and classification methods. The discussion also emphasizes the need for statistics and computational techniques to be supplemented with economics. The success of a forecast in this environment hinges on the economic consequences of the actions taken as a result of the forecast, rather than on typical statistical metrics of prediction accuracy.     

Integrating ecosystem services into conservation assessments: A review

A call has been made for conservation planners to include ecosystem services into their assessments of conservation priority areas. The need to develop an integrated approach to meeting different conservation objectives and a shift in focus towards human wellbeing are some of the motivations behind this call. There is currently no widely accepted approach to planning for ecosystem services. This study contributes towards the development of this approach through a review of conservation assessments and the extent to which they include ecosystem services. Of the 476 conservation assessments identified by a set of search terms on the Web of Science, 100 were randomly selected for this review. Of these only seven had included ecosystem services, while another 13 had referred to ecosystem services as a rationale for conservation without including them in the assessment. The majority of assessments were based on biodiversity pattern data while 19 used data on ecological processes. A total of 11 of these 19 assessments used processes, which could be linked to services. Ecosystem services have witnessed an increase in attention received in conservation assessments since the year 2000, however trends were not apparent beyond this date. In order to assess which types of ecosystem services and how they have been accounted for in conservation assessments, we extended our review to include an additional nine conservation assessments which included ecosystem services. The majority included cultural ecosystem services, followed by regulatory, provisioning and supporting services respectively. We conclude with an analysis of the constraints and opportunities for the integration of ecosystem services into conservation assessments and highlight the urgent need for an appropriate framework for planning for ecosystem services.

长三角地区产业结构高级化及影响因素

本文根据三次产业结构比重,构造了长三角江浙沪三地的产业结构层次系数,对三地产业结构高级化变动进行了分析,发现产业结构高级化存在区域差异和趋势趋同特征,继而使用1990—2008年面板数据对影响产业结构高级化的影响因素进行了实证检验。结果发现:科技创新和政府规模对于产业结构高级化有正向作用,进出口贸易对于产业结构升级产生负向作用,FDI和社会投资作用则不太明显。其政策含义在于,在长三角产业结构升级化进程中,更应该注重科技创新和技术进步来推动产业结构高级化发展,从而实现产业结构调整和经济发展转型。
