农地经营权流转的农户融资诉求效应研究 ——基于中国家庭调查数据的实证分析

研究目的：基于农户潜在融资需求与渠道偏好视角研究农村土地经营权流转的农户融资诉求效应。研究方法：二元及排序Logit模型。研究结果：（1）在农户潜在融资需求方面,农村土地经营权流转行为对农户潜在融资需求促进作用明显。流转规模越大,农户潜在融资需求越高;流转合同签订,农村土地经营权流转的稳定性和农地可抵押性增强,农户潜在融资需求越高。（2）在融资渠道偏好方面,流转后农户沿着“非正规渠道—非正规与正规两者兼有—正规渠道”的偏好路径转变,逐步增加对于正规渠道的偏好。流转规模扩大及流转合同的签订会显著提升农户对正规渠道的偏好。研究结论：农村土地经营权流转会引致农户产生融资诉求效应,增加农户潜在融资需求,促使农户融资渠道向正规化转变。

Demand responsive transport: towards the emergence of a new market segment

This paper focuses on recent British experience with telematics-based Demand Responsive Transport (DRT) services in rural areas. In recent years, the ability of DRT concepts to provide efficient, viable transport services has been greatly enhanced by the use of transport telematics as demonstrated in a variety of environments across Europe. The success of British local authorities in winning substantial funding under the Rural and Urban Bus Challenge programmes for the implementation of DRT has resulted in widespread interest in flexible forms of transport. It is thus timely to evaluate the impact of this substantial investment. Drawing on the experience of a number of UK schemes, the paper assesses the reasons for the new-found success of what is becoming a relatively well-accepted mode by concentrating on a variety of factors including: service characteristics (particularly route flexibility, flexibility of booking method and pre-booking regime), emerging markets and the overall contribution of DRT to increased social inclusion and intermodality. Impediments to the development of DRT services are highlighted. The paper also discusses current research into the next generation of DRT services and concludes by identifying some key issues for policy-makers concerned with the future implementation of DRT services.     

The evaluation of demand responsive transport services in Europe

Over the last decade Demand Responsive Transport (DRT) services have grown in popularity for several reasons including: the shortcomings of conventional regular bus and taxi services; shortcomings of special transport services; and new developments in community transport. Traditional dial-a-ride services have often been criticised because of their relatively high cost of provision, their lack of flexibility in route planning and their inability to manage high demand. The potential for overcoming these limitations may be realised through the introduction of telematics-based DRT and this has been widely demonstrated, for example, in recent research funded by the European Commission (e.g. the DGXIII-funded SAMPO and SAMPLUS projects). This paper provides an introduction to the concept of telematics-based DRT services and presents the results of the evaluation of a set of DRT technologies and operations at urban and rural sites across Europe. The paper offers discussion in terms of the key issues that influence the introduction of DRT services.     

矿物微粉对水泥基混合料抗压强度的影响

为了了解矿物微粉对混凝土性能的影响,利用可压缩堆积模型(CPM)计算了不同体系胶凝材料的堆积密实度,研究了矿物微粉级配及其相对掺量对低水胶比水泥基混合料抗压强度的影响。结果表明,胶凝材料的堆积密实度与水泥基混合料的抗压强度有很强的对应关系;当堆积密实度相差不大而化学效应相差较大时,化学效应越大,抗压强度越大。     

IMF救援方案宏观绩效的实证研究

本文采用面板数据模型和事件分析法考察了1995—2002年间接受IMF救援的韩国、泰国、罗马尼亚、墨西哥和哥伦比亚等五国的宏观经济绩效，发现IMF救援方案对受援国内部平衡指标并无明显作用，对外部平衡的恢复却起到一定的积极作用，而且这种积极的作用在接下来两年中一直有效。但通过进一步研究，叉发现这种积极作用的实现是以抑制经济的短期发展为代价的，这可能导致受援国在未来的某个时间再次需要IMF的援助。因此本文认为当前迫切地需要对IMF的救援机制进行改革。
