地方政府财政支农支出与农村居民消费——来自中国29个省市面板数据的经验证据

本文在消费者最优消费路径选择的基本框架下,构建了一个政府财政支农与农村居民消费的动态最优化模型,理论分析表明:地方政府财政支农支出的增加,对于农村居民消费水平的提高具有促进作用。基于1995-2008年的省际面板数据,采用工具变量GMM方法对该结论进行的实证检验发现:在通过多工具变量克服变量内生性之后,地方政府财政支农支出对农村居民消费具有显著的促进作用,地方政府财政支农支出每增加1%,我国农村居民消费将增加0.1367%;进一步的因素分解显示,地方政府财政支农支出对农村居民消费的平均贡献度为8.72%,且有逐年增大的趋势。此外,财政支农支出对农村居民消费的影响存在区域差异性,即财政支农支出对我国中西部地区农村居民消费的影响程度大于东部地区。     

基于循环经济的绍兴休闲观光农业发展研究

［目的］休闲观光农业建设是绍兴市产业转型升级的关键一步,探寻休闲观光农业新模式,能够为休闲农业发展提供理论参考。［方法］文章采用变异系数法确定指标权重,多因素综合分析法测算观光农业发展水平,从循环经济角度出发,评价2001—2016年绍兴市休闲观光农业发展可持续性,提出发展中存在的问题并探索循环型的休闲观光农业新模式。［结果］（1）2001—2016年以来,经济发展可持续性得分较高,资源环境可持续得分次之,循环经济可持续发展偏低。（2）现阶段绍兴市休闲观光农业发展主要存在休闲观光农业自然环境不断遭到破坏,休闲观光农业缺乏整体规划,休闲观光农业旅游支撑体系不够健全等问题。（3）未来发展中,循环经济发展下的休闲观光农业可以开发建设时空复合循环型、资源综合利用循环型、能量多级利用循环型、综合开发利用循环型等4种模式。［结论］未来绍兴市应将循环经济的理念融入到休闲观光农业中,因地制宜,科学选择循环型休闲观光农业发展模式; 规划先行,科学利用农业旅游资源; 强化保障,建立休闲观光农业支撑体系,全面推动休闲观光农业健康持续发展。     

农产品绿色技术壁垒形成的政治经济学原因探究

近年来，绿色技术壁垒问题正越来越引起人们的关注。一些发达国家以保护生态环境、保护人类、动植物生命和健康为由制定复杂苛刻的环境保护措施，对国际贸易造成了不必要的障碍。因为大部分农产品和食品的出口限制主要以保护环境和人类健康为由，如检测出进口农产品有毒成分残留超标，含有已禁用的农药和化学药品等，所以农产品贸易受绿色技术壁垒的影响更为严重。本文尝试从政治经济学的角度深刻分析农产品遭遇绿色技术壁垒的原因。     

从能源短缺看我国农业的发展方向

随着全球经济的快速发展,能源问题日益凸现,能否解决好能源短缺问题决定着各国经济能否持续发展。我国是农业大国,农业一直是我国的基础性产业,因此,解决好农业能源问题显得至关重要。本文认为,我国农业的发展应该走节约型农业道路,即发展能源农业,其不仅能够缓解农业能源短缺,而且还能促进农民收入增长,有效改善环境。     

区块链+农业：应用与未来趋势

区块链技术在农业中的应用问题已成为国内产业规划以及经济领域研究的热点问题。以国内外区块链相关研究成果为基础,从经济学视角,系统梳理区块链应用于农业的经济学脉络,分析区块链在农业应用的经济学逻辑。研究表明,当前区块链技术在农业中的研究主要集中在农业物联网、农业大数据、农产品安全管理、农村金融、农业产业链及农业供应链等领域,但由于区块链技术在农业中的应用尚处于起步阶段,仍然存在一些问题与争议。为此,形成区块链在农业中应用的经济学研究体系,完善相关研究方法,深入挖掘区块链在农业中的应用场景,促进区块链在农业中的规范合理应用是下一步的研究重点。     

我国农业现代化道路的制度困境与重构

虽然中央为农村改革发展和制度建设指明了方向,但是由于我国尚处于新旧体制过渡时期,制约我国农业现代化发展的制度困境在一定时期内还将长期存在。深化农村土地产权制度改革、创新农产品流通体制,发展企业化的批发市场、加快农村金融改革与创新,重构服务“三农”的农村金融体系、构建民营农场制度、创新农村人力资本形成与积累制度,将为破解我国农业现代化道路上的制度困境提供有益出路。     

A critique of high-value supply chains as a means of modernising agriculture in China: The case of the beef industry

China has embarked on an agricultural modernisation program with far-reaching implications for rural development, food safety and trade. A major focus of China’s agricultural modernisation program has been to build high-value supply chains and large, modern agro-industrial enterprises. This paper provides a critique of these efforts in the case of the high-value beef supply chain. It finds that interventionist policies to fast-track the development of high-value supply chains have perverse outcomes and that a more incremental and facilitative approach to modernisation should be pursued based around the development of mid-value supply chains.     

金融创新支持现代农业发展中存在的问题及对策

近几年来,延边州金融机构不断进行农村金融服务方式和产品创新尝试,取得了一定成效。但仍存在信贷信贷资金外流严重、农村金融创新还受到较多因素制约,亟待改进。     

The role of price risk in China’s agricultural and fisheries exports to the US

This article explores the effect of price risk on the US importers’ optimal allocation of agriculture imports between the major supplier, China, and other competing countries. We first modify a demand system to account for the impacts of own-price risk and cross-price risk, and then apply the model to 16 agricultural and fisheries commodities exported to the US. The estimation results show that importers are sensitive to price risks of 14 Chinese commodities. Comparisons between price risk–trade relations of agricultural and fisheries products and between trade effects of cross-price risk on Chinese goods and substitutes provide strong evidence for explaining the observed trade patterns. Our study highlights the importance of price stability in promoting international trade, especially from developing countries to developed countries.     

How can the EU climate targets be met? A combined analysis of technological and demand-side changes in food and agriculture

To meet the 2 °C climate target, deep cuts in greenhouse gas (GHG) emissions will be required for carbon dioxide from fossil fuels but, most likely, also for methane and nitrous oxide from agriculture and other sources. However, relatively little is known about the GHG mitigation potential in agriculture, in particular with respect to the combined effects of technological advancements and dietary changes. Here, we estimate the extent to which changes in technology and demand can reduce Swedish food-related GHG emissions necessary for meeting EU climate targets. This analysis is based on a detailed representation of the food and agriculture system, using 30 different food items.We find that food-related methane and nitrous oxide emissions can be reduced enough to meet the EU 2050 climate targets. Technologically, agriculture can improve in productivity and through implementation of specific mitigation measures. Under optimistic assumptions, these developments could cut current food-related methane and nitrous oxide emissions by nearly 50%. However, also dietary changes will almost certainly be necessary. Large reductions, by 50% or more, in ruminant meat (beef and mutton) consumption are, most likely, unavoidable if the EU targets are to be met. In contrast, continued high per-capita consumption of pork and poultry meat or dairy products might be accommodated within the climate targets. High dairy consumption, however, is only compatible with the targets if there are substantial advances in technology. Reducing food waste plays a minor role for meeting the climate targets, lowering emissions only by an additional 1–3%.
