美国农业保护政策简介

农业是美国所有产业中竞争最激烈的产业之一 ,农业的激烈竞争主要是由进入“门槛”低所致。在 1981到 1990年期间 ,美国联邦政府花在农业上的补贴超过 2 50 0亿美元。价格补贴是美国农业保护政策的基础 ,成本补贴又使因价格补贴导致的市场过剩更加严重。对农民采取直接收入补贴政策的好处在于 :该政策能在不引起市场价格和农业产出扭曲的情况下 ,保证农民收入能达到一定水平     

Multilevel embeddedness: The case of the global fisheries governance complex

This paper explores how bilateral and multilateral clustering are embedded in a multilevel system of interdependent networks. We argue that in complex systems in which bilateral and multilateral relations are themselves interrelated, such as global fisheries governance, embeddedness cannot be reduced to unipartite or bipartite clustering but implicates multilevel closure. We elaborate expectations for ties’ multilevel embeddedness based on network theory and substantive considerations and explore them using a multilevel ERGM. We find states’ bilateral ties are embedded in their shared membership in multilateral fisheries agreements, which is itself clustered around foci represented by similar content and treaty secretariats.     

Myths and realities about input subsidies in sub‐Saharan Africa

Using a recent public expenditure dataset, this article proposes a ‘reality check’ of the level and composition of input subsidies in nine African countries between 2006 and 2013. Results show that input subsidies (1) received close to 35% of agricultural‐specific expenditure on average and (2) cover a variety of interventions, including investments in capital, such as on‐farm irrigation, and in on‐farm services, such as inspection or training. Further, the figures show that input subsidies tended to become entrenched in agricultural budgets over time, leading to sub‐optimal execution rates, and were primarily funded by the national taxpayer, while donors invested more in public goods. Findings confirm that input subsidies crowded out other spending categories likely to be more supportive of long‐term agricultural development objectives. The article concludes that the political economy of input subsidies should be directed to making more concrete efforts to attain a better balance of public expenditure on agriculture. Furthermore, policy‐makers should aim to increase the efficiency and policy coherence of input subsidies, since merely abolishing them is likely to be unfeasible in the short term.     

Corporate statement serving as information subsidies in the product-harm crisis

This study explores the attributes of a crisis statement which influence its utility as an information subsidy in the process of product-harm crises in China. Through investigating and analyzing 92 statements released in times of product-harm crises, the results show that the form in which the statement is released, and the length of the statement have significant effects on whether the statement will be quoted fully or partially by the news media.     

家电下乡政策的消费效应评估——基于全国221个村庄的4年跟踪调查

以全国221个村庄所获得的4年调查数据作为研究基础,对"家电下乡"政策的消费效应予以评估和分析。调查表明,家电下乡政策消费效应的最大特征是农民消费需求的释放,其中包括全国消费总额的上升,户均消费额增幅达到8成,全国各地消费总量和户均消费数量的增加。但家电下乡政策的消费效应在实践中也遇到了持续性疲软的难题,如农民收入的限制作用,农民购买下乡产品比重偏低,政府补贴额和补贴程序不足,政策宣传和解说不到位。为了使家电下乡政策的消费效应持续起效,必须不断完善政策,使家电下乡政策的实惠真正落实到农民身上。     

我国新型农村社会养老保险经济支持能力研究

老农保的失败让人们对新农保充满期待的同时也存有几分担忧,他们担心农民的经济承受力。更怕财政不堪重负。为坚定领导层试点、推广新农保的信心和决心,加快新农保发展步伐,本文在测算新型农村社会养老保险的经济负担的基础上,对农民个人和政府两方面的经济支持能力进行分析,认为只要制度设计合理,农民个人和政府是有能力承担这部分支出的。

论发展低碳经济的减排政策工具

为解决温室气体排放的外部性问题,各种减排政策工具应运而生。根据作用效果的不同,可分为抑制排放的政策工具和鼓励促进低排放的政策工具。在抑制排放的政策工具中,碳税和碳排放交易采用了不同的政策机理,碳税更适用于市场机制不完善的发展中国家,而碳排放交易则更适用于市场机制比较完善、经济发展成熟的发达国家。在鼓励促进低排放的政策工具中,通过综合运用财政补贴、税收优惠和差别定价等措施,对可再生能源的发展可发挥重要作用。     

欧盟共同农业政策改革与WTO多哈回合谈判

欧盟共同农业政策(CAP)是欧盟实施的第一项也是最重要的一项共同政策,40多年来,在内外压力下,它经历了多次调整和改革。2004年8月,世贸组织成员达成了多哈回合框架协议。在核心领域农业问题上,包括美国、欧盟和日本在内的发达成员承诺将最终取消出口补贴,大幅度削减国内支持,实质性改进市场准入条件。如何与WTO新的自由贸易协议相协调,欧盟共同农业政策面临着新的挑战。
