对农民专业合作经济组织发展中若干问题的思考

农民专业合作经济组织近期在我国产生并得到发展有其客观必然性。它既不同于我国20世纪五六十年代推进的合作化运动所追逐的目标－初级社、高级社、人民公社、也不同于目前普遍存在的带有社区特征的农村集体经济,更不同于近些年在农村广泛发展的体现投资多元化特点的股份合作制经济。它有着特定的特征、内涵、经营体制和营运原则。政府应制定优惠政策支持农民专业合作经济组织的发展,并尽快确立农民专业合作经济组织的法律地位。     

我国开征储蓄存款利息税的宏观经济效应分析

自我国开征储蓄存款利息税以来，居民储蓄存款并没有停止持续上升的势头，利息税政策基本上无效。其原因是利息税对储蓄的收入效应为正，替代效应为负，且收入效应的绝对值大于替代效应的绝对值。这样，征税后对消费和储蓄的总效应为消费减少而储蓄增加。为此政府应采取措施改善居民对未来收支的预期，并且应加快建设完善高效的资本市场的步伐，引导一部分储蓄存款进入证券投资领域。     

中国与印度外贸比较研究

中国与印度两国国情有很多共同之处，目前是全球经济增长最快的两个国家，两国经济发展模式为世界瞩目。两国的外贸规模和发展速度都呈上升趋势，但两国外贸发展的条件不同，外贸水平以中国为佳，而印度的战略性贸易政策值得借鉴。另一方面，中印之间的贸易问题不少，既有结构性问题，也存在保护主义和渠道沟通问题，因此，应加强双边外贸的发展潜力，并拓展双边经济技术合作的领域。

Higher Intensity,Higher Profit? Empirical Evidence from Dairy Farming in New Zealand

Over the last two decades there have been significant and well‐documented changes in the nature and structure of New Zealand dairy production. One particular feature has been a marked shift in the ‘input intensity’ of dairy farming systems through increased use of supplementary feed. These changes have generated debate about the impact of dairy farm intensity on the performance of farm businesses and the competitiveness of the New Zealand dairy sector. Using a novel econometric approach, we assess statistically the impact of three types of dairy farming systems on milk production and financial performance, using farm business data provided by DairyBase^®. Our empirical results show that higher input systems perform significantly better physically than lower input systems, but not financially. The disaggregated analysis suggests that the average treatment effects differ by region and performance quantiles.     

A Question of Integrity: Variants of Bt Cotton,Pesticides and Productivity in Pakistan

Bt cotton remains one of the most widely grown biotech crops among smallholder farmers in lower income countries, and numerous studies attest to its advantages. However, the effectiveness of Bt toxin, which depends on many technical constraints, is heterogeneous. In Pakistan, the diffusion of Bt cotton occurred despite a weak regulatory system and without seed quality control; whether or not many varieties sold as Bt are in fact Bt is also questionable. We utilise nationally representative sample data to test the effects of Bt cotton use on productivity. Unlike previous studies, we invoke several indicators of Bt identity: variety name, official approval status, farmer belief, laboratory tests of Bt presence in plant tissue, and biophysical assays measuring Bt effectiveness. Only farmer belief affects cotton productivity in the standard production model, which does not treat Bt appropriately as damage‐abating. In the damage control framework, all Bt indicators reduce damage from pests. Biophysical indicators have the largest effect and official approval has the weakest. Findings have implications for impact measurement. For policy‐makers, they suggest the need, on ethical and productivity grounds, to improve variety information and monitor variety integrity closer to point of sale.     

关于林业生物灾害防治工作的调查报告

通过对江西、浙江、辽宁、河北、重庆等省(市)林业生物防控工作的调查,发现存在防控体系和防控能力不强,防控御灾"各自为战,配合不够",防控管理"越位、错位、缺位",防治减灾"钱随灾流、人随灾走"等问题。因此要树立森林健康理念,提高森林自身"抗性",将预防林业生物灾害贯穿林业生产全过程。
