【摘要】 转基因抗虫玉米能够抵抗玉米螟危害从而避免虫害造成的产量损失。本文应用国际事务政策研究所开发的DREAM分析系统,对转基因抗虫玉米在中国商业化的经济收益进行事先评价,期望为相关研究和决策提供参考。研究表明,抗虫玉米能够带来较高的经济收益,2008—2012年累计产生经济收益可达22.79亿元,其中生产者剩余占1/4,其余为消费者剩余。与节省的成本相比,种子价格对B t玉米商业化经济收益的影响要大。更多还原

【Abstract】 Corn is a major food and feed crop in China and it is planted in large acreage.Borer resist corn,Bt corn,can greatly reduce production lose from this major insect in the field.The current study hypothetically assessed the economic impact of the commercialization of transgenic Bt corn in China using the computational research model DREAM.The result suggested Bt corn would bring high economic benefit in 2008 through 2012.The accumulated economic gains are 2.28 billion Yuan,and the producer surplus accounts for one quarter and the rest goes to the consumer surplus.Seed price is a stronger influence factor to the economic benefit raised from Bt corn commercialization in China comparing to the cost saved from switching from conventional corn to transgenic Bt corn.更多还原
