农村居民和谐消费的乘数效应和生态效应分析
,
农业现代化研究 , 2008,
Abstract: 通过对农村居民和谐消费特征的研究,认为要实现农村居民和谐消费,必须注重对生态环境共生性适应维度的培育。农村居民的消费决策或消费行为与经济、社会文化、环境三个维度相协调,农村居民和谐消费的乘数效应和生态效应将得以充分发挥。实现农村居民和谐消费应该主要从收入增加、农村生态环境改善、消费观念转变以及政府政策支持4种途径来实现。

北方园艺 , 2014,
Abstract: 基于对陕西省关中地区水果和蔬菜专业合作社的调研,找出社员对农民合作社满意度的影响因素。利用二元Logistic方法分析调研数据,得出社员年龄、参加合作社的种植收入、加入合作社的时间、理事长的文化程度、合作社的注册资本金及合作社是否有政策支持是影响陕西关中地区合作社满意度的因素。最后,简单分析了原因并提出意见。

Abstract: 根据定性评价法将合作社与社员间的利益联结紧密程度总结为3种依次递进的类型。利用陕西关中地区果蔬类农民专业合作社的调研数据,构建有序?Probit?模型,从合作社基本特性、合作社产品生产特性、合作社产品的市场化特性等3个方面分析了影响合作社与社员利益联结紧密程度的因素。结果表明合作社示范级别、前八大股东持股量和理事会成员持股量、产品加工情况与认证情况、产品直销比例等因素显著;最后提出组建联合社、开发有效的盈利模式以及增强社员的产业化意识的培育等建议,冀求提升合作社与社员的利益联结紧密程度。

陕西省农业生产条件现代化与农业经济发展的灰色关联分析
雷玲,苏夏琼,
农业现代化研究 , 2011,
Abstract: 农业现代化是新农村建设的重要内容,是农民增收和农村发展的条件。本文分析了陕西农业发展现状及存在的问题,并运用灰色系统理论中的灰色关联分析模型,分析了农业生产条件现代化各指标因素对陕西农业经济发展的影响程度。结果表明:农机化水平对陕西农业经济发展的影响程度最大,其次是电气化水平,而农药和农用薄膜对农业经济的影响程度最小。根据灰色关联分析的结果并结合陕西农业的现状,提出了促进陕西现代农业发展的若干建议。

农民组织化程度衡量及其评价
Evaluation of Degree of Farmers’Organization

,,,郭海丽

Abstract: 现阶段,我国农民组织化程度呈低向度发展趋势,农业生产经营成本过高,农民收入水平降低,农产品交易困难等问题仍然是我国农业发展的重要障碍。提高农民组织化程度是保障我国农业发展、农民增收的有效途径。综合现有的理论成果,界定了农民组织化的概念,并在此基础上构建了评价农民组织化程度的指标体系,基于235户社员的调查数据,采用主成分分析方法测算农民组织化程度及其影响因素。
At present, the degree of farmers’organization becomes increasingly lower in China. The high operating cost of agricultural production, dropping of farmers’ income level and troubles in the trading of farm products are major obstacles for agricultural development. Enhancing the degree of farmers’ organization proves an effective way to promote agricultural development and increase of farmers’income. Synthesizing the existing research findings, this paper firstly defines the concept of farmers’ organization, and then it constructs an indicator system for its evaluation. Finally it estimates the degree of farmers’organization and its influencing factors by using principal components analysis method based on the survey data of 235 members.
粮食种植户生产环节外包选择行为分析
Farmers’ Selection Behavior in Process of Grain Production Stage Outsourcing

,,,陈绳栋,,
- , 2017,
Abstract: 在构建粮食种植户生产环节外包选择行为理论框架的基础上,运用河南和山西两省小麦主产区2015年631户小麦种植户的第一手调查数据,采用Ivprobit模型分析验证资本密集环节和劳动密集环节的外包行为影响因素,以及资本要素与劳动要素的内部影响关系。研究得出:粮食种植仍以小规模农户为主。资本密集环节外包的比例较高,尤其是机械替代性较强的耕地、播种和收割环节。劳动密集环节外包的比例较低。资本要素对粮食生产的纵向分工和规模化种植有重要的影响。劳动要素对种植户劳动力的非农转移和种植业的兼业化生产具有重要的影响。依据研究结论提出以下建议:鼓励农业社会化服务体系的建设,满足多种农业生产主体的不同需求。鼓励外包服务主体对烘干设施的购置,建设有效外包服务的供需市场。鼓励劳动力从农业向非农业的转移,同时提高专业种植户的农业生产技能。
Stage outsourcing behavior of grain producers has become increasingly important because of the rapid transformation of China’s countryside. However, few studies have addressed this issue using a theoretical framework. We set out to fill this gap in the literature by developing a theoretical model that integrates determinants of grain farmers’ outsourcing behavior and the number of grain growing stages outsourced, and use a Probit Model to estimate the influencing factors of seven stages outsourcing and the number of outsourcing. Moreover, a instrumental variable probit model is used to determine whether the influencing factors are endogenous or not. In particular, we use 2015 data from 631 wheat farmers in Henan and Shanxi provinces. The survey covered 7 wheat growing stages in winter period. Descriptive and regression results show that:(1) Small scale grain farmers are in the majority. (2) The proportion of capital intensive outsourcing is higher, in addition to the ploughing sector, sowing sector and harvesting sector, which are strong mechanical replacement parts; on the country, labor intensive outsourcing ratio is low. (3) Capital factors have an important influence on vertical division of grain production and scale production. (4) Labor factors have an important influence on the non agricultural transfer of plantation labor and the part time farming of grain planting industry. In light of these findings, it is suggested that the amount of machinery for grain farmers is gradually increased to develop the supply and demand of outsourcing market. Policy maker should encourage non agricultural labor transfer and improve the ability of non agricultural labor workers, at the same time, strengthen the training efforts of grain planting technology, and especially pay attention to the model effect of science and technology demonstration households.
