摘　　要：以江苏棉区为调查对象,按地区调查农户种植转基因Bt棉和常规棉品种的经济收益情况,并对其进行了分析比较。结果表明:种植Bt棉尽管可减少棉田农药施用量、节省劳动力成本,但因Bt棉较常规棉产量明显偏低,加上Bt棉种子价格昂贵,Bt棉种植户的直接经济收益有不同程度的下降,降幅最大的连云港市为10.36%,每公顷收入减少了1710元。进一步对Bt棉种植户的直接经济收益、经济收益不确定性及由种植Bt棉带来的其他经济收益的分析表明,Bt棉产量较低是农户种植Bt棉直接经济收益下降的主要原因。Spreading of genetically modified plants is a revolutionary progress of agriculture development in the 20 century over the world. So far, transgenic Bt cotton is one of the most successful plants for commercially using. A survey was conducted in different areas in Jiangsu province and a comparison was made for the net benefit of farmer between conventional cotton and Bt cotton. The results indicated that, although Bt cotton planting decreased the cost of insecticides and labor, net benefit of the Bt cotton planting decreased for cotton farmers, mainly because the yield of the Bt cotton was lower than the conventional cotton and the seed cost of Bt cotton was higher than the conventional. A decrease of 1()710 RMB Yuan·hm^(-2)occurred for Bt cotton planting farmer in Lianyungang, which was the most among the surveyed areas. Analysis demonstrated that more than 77% of the decrease of net benefit was attributed to the decline of yield of Bt cotton. The evaluation of farmer net benefit of Bt cotton planting, the uncertainty of benefit of Bt cotton and other indirect benefit from Bt cotton were discussed in the paper.
