金紫山风电场一期工程风机基础设计

风电场的风力发电机组基础形式主要有扩展基础、桩基础和岩石锚杆基础,具体采用哪种基础应根据建设场地地基条件和风力发电机组上部结构对基础的要求确定。文章以广西资源县金紫山风电场一期工程为例,介绍山区风力发电机组基础的设计。     

西部地区农户金融需求及其影响因素的实证分析

以中国西部地区农户的借贷为基本研究对象,结合有关调查数据,分析了农户的信贷需求情况,并用Probit模型分析了西部地区农户金融需求的影响因素。分析表明：西部地区农户具有广泛的金融需求但从正规金融机构获得贷款的比例较低,其对利息具有一定的承受能力,借贷以短期、小额为主,用途兼有生活与生产性、但以生活性为主,借款未归还的比重较低。人口、劳动力、学生人数、劳动力平均年龄、劳动力最高受教育程度、家庭经营的土地面积、家庭收入、家庭储蓄水平、家庭收入来源、家庭距正规金融机构的距离、信用社是否对农户的评级、农户所在地是否存在有息借贷等指标,是影响西部地区样本农户是否具有金融需求的显著因素。     

农业产业化利益分配机制研究——以广东省为例

利益分配机制是农业产业化发展的关键和核心。文章立足于广东省农业产业化利益分配机制状况调查,从农业比较利益、龙头企业与农户的地位和权责利关系等方面研究了我国农业产业化利益分配机制中存在的问题及原因。文章认为,完善农业产业化利益分配机制应理顺农业与非农业关系、壮大龙头企业、强化契约管理、培育发展中介组织及建立风险机制。     

休闲农业发展的国际经验及其现实操作

休闲农业长期以来被认为是新型农业、农家乐、农业经营形态。由于理论上的误区和路径依赖的影响,休闲农业的发展存在一些问题,需要理论探索和创新。国内外休闲农业发展的经验和理论分析表明,休闲农业是一种旅游产品,按旅游产品的要求来设计和开发休闲农业,将是休闲农业实现科学发展的有效途径。     

农村劳动力市场发育对农村土地流转的影响分析——基于农户调查的实证研究

利用农户调查数据,运用多元回归模型实证分析了农村劳动力市场发育对农地流转的影响。模型估算结果表明：在表征农村劳动力市场发育程度的四个变量中,工资自主决定程度对农地转出率影响最大,回归系数达到了0.528,即该变量每增加一个单位将会使农地转出率增长52.8%。就业流动自由度对农地转出率的影响也比较大,回归系数为0.423。就业市场服务体系完善程度对农地转出率的影响相对较小,回归系数为0.126。在此基础上,得出相应的政策启示。     

A typology for defining agritourism

Agritourism has been studied in various ways and contexts. It can be argued, however, that studies have yet to provide a clear and basic understanding of the characteristics that underpin and define agritourism. This paper proposes an original typology for defining agritourism by identifying the key characteristics currently used to define agritourism in the literature and organising them into a transparent and structured framework. For the first time, the agritourism typology clarifies and classifies definitions of agritourism that currently exist in the literature. It therefore offers a comprehensive framework that can be used as a basis for more informed debate and discussion and for future empirical research.     

Do family farms really converge to a uniform size? The role of unobserved farm efficiency*

We analyse the growth of family farms in Israeli cooperative villages during a period of economic turmoil. We use instrumental variables to account for the endogeneity of initial farm size, and correct for selectivity as a result of farm survival. We also include a technical efficiency index, derived from the estimation of a stochastic frontier production model, as an explanatory variable. Our aim is to check whether ignoring efficiency could have been the reason for convergence results obtained elsewhere in the literature. We found that technical efficiency is an important determinant of farm growth, and that not controlling for technical efficiency could seriously bias the results. In particular, larger farms are found to grow faster over time, while without controlling for technical efficiency the farm growth process seemed to be independent of initial farm size. The increasing polarisation of farm sizes in Israel has ramifications for the inefficiencies induced by the historical quota system, for the political power of the farm sector and for the social stability of farm communities.

A multi-criteria assessment of tourist farm service quality

Farm tourism is a significant means of supplementing farmers' incomes. This paper presents a methodology for ranking tourist farms by using a multi-criteria model based on the qualitative multi-criteria modeling methodology, DEX, to assess service quality. The software tool DEXi was used to achieve this end. The model was then applied to seven tourist farms with data derived from questionnaires completed by tourist farm operators and guests. The results are shown as service quality assessments for individual farms. The potential of the model for assessing the farms is demonstrated with the aim of providing a comprehensive explanation and justification of the assessment technique. It also indicates potential improvements that farms can make through “what-if” analysis and visualization. Despite limitations, such as use of qualitative data only, the approach is proposed as being both appropriate and advantageous when compared with other means of ranking enterprises.
