“十二五”时期中部传统农业大省外围区与中心区经济协调发展研究

文章提出了在保障国家粮食安全、不牺牲中心区发展速度等约束条件下,促进中部传统农业大省外围区与中心区经济协调发展的总体方案,即加快外围区农村综合改革,培育与壮大外围区区域性中心城市,推进省级边界区域的开放与合作。在这一方案的贯彻实施中,应当注重农民专业合作组织的建设,强化外围区中心城市的产业支撑作用,推动边界区域一体化合作组织的成立。     

基于技术风险的研发联盟政府补贴政策研究

文章考虑研发存在技术风险,建立了合作研发博弈模型,研究了政府不同财政补贴方式（研发投入补贴和产品补贴）下的企业研发和生产策略。通过理论和数值仿真分析找出了不同补贴政策下的企业最优策略和相应的社会福利,并就政府的研发补贴政策提出了相应建议。研究表明,两种补贴政策均无法实现社会福利的最优解,研发难度较小的情况下宜采用研发投入补贴,研发难度较大的情况下应采用产品补贴,以此提高企业研发投入和社会福利。     

河北省贫困农村地区信贷担保体系的建立及模式选择

"三农"问题的解决离不开农村金融的支持。然而河北省贫困农村地区却是"农民贷款难、金融机构难贷款"并存。本文认为设立农村信用担保机构、选择适合贫困地区的担保模式将有助于这一矛盾的解决。     

中国清洁能源产品偷吃美国政策福利了吗

在补贴强度一致的情况下,不管补贴方式有何差异,清洁能源产品生产者和消费者获得的补贴分享是相同的。美国对消费环节补贴会流入中国生产企业,中国对生产环节的补贴同样也流入了美国消费环节。从整个清洁能源产业来看,中国是否"偷吃"了美国的政策福利取决于该产业的供求函数。     

新形势下我国农业产业链危机分析

外资在国内的抢购粮食行为再次拉响了粮食安全的警报。文章以农业产业链为对象,分析了在农资供应、粮食生产和购销、粮食加工及制成品销售等方面潜藏的危机。文章从政府扶持、做大做强粮食国企、培植品牌和打击粮食投机等方面探讨了新形势下打造我国安全农业产业链的思路。     

浅议完善和健全我国农村社会保障制度之必要性

农村社会保障制度是国家社会保障的重要组成部分,它关系到广大农民群众的切身利益,是社会稳定与国家长治久安的重要保证。本文从五个方面分析和探讨了完善和健全我国农村社会保障制度的必要性,为各级行政部门下定决心,排除干扰,高度重视并切实有效的解决我国农村社会保障实践中存在的各种问题,提供了理论依据。     

航电枢纽工程财务增效机制研究

Methods and tools for integrated assessment of land use policies on sustainable development in developing countries

For stimulating sustainable development in developing countries, land use patterns and land use changes are considered critical, and therefore effective and efficient land use policies are needed. In this paper we present a methodological framework that has been developed in a joint European and developing countries project (LUPIS – Land Use Policies and Sustainable Development in Developing Countries), to assess the impact of land use policies on sustainable development in developing countries. An illustrative application is presented for a case study in China, where water pollution due to agriculture in Taihu Basin is a major problem.     

Can farmers extend their cultivation areas in urban agriculture? A contribution from agronomic analysis of market gardening systems around Mahajanga (Madagascar)

The rapid urbanization in developing countries implies an increasing pressure on urban agriculture for production. As most perishable food products come from this agriculture in close proximity to population concentrations, we analysed from an agronomic point of view how market-garden farmers can meet this increasing urban demand. This work took place in the case of Mahajanga, a secondary city with high increasing demographic rate on the Northwest coast of Madagascar. Based on preliminary surveys to characterize the farming systems (on a sample of 91 farms), 11 market-garden farmers chosen in the three main agricultural zones of the urban area were surveyed during two years. Surveys aimed at understanding their decision rules in crop choices, crop allocation to land and resource management, and to estimate their room for manoeuvre to increase their leafy vegetable areas under cultivation. The wholesalers and retailers who buy the farmers’ produce were also surveyed. A previous model of decision rules regarding crop location on farm territory was used to analyse the on-farm surveys and cartographic methods (GIS and on-farm manual representations) were used to quantify the land use. We highlight the following major points. (1) The leafy vegetable production in the surveyed farms already intensively uses land: farmers have complex decision rules largely depending on the water dynamics in the two main environments (lowlands and lakesides) where leafy vegetables are cultivated during the dry season. (2) The scarcity of farmers’ resources (labour money and water) leads to very little internal room for manoeuvre to increase the leafy vegetable production in the farms. (3) At territorial level however, some land reserve exist in one of the lowlands, but not on lakesides. The water availability for agriculture must be better informed through specialized hydrologic studies, as one of the main constraints nowadays to extend the agricultural area. An extrapolation to other cases of urban agriculture is then discussed as well as the role of agronomy to help urban planners to consider the place of agriculture in the urban development.
