摘要本文考察了社会网络在苏云金芽孢杆菌(Bt)棉花采用过程中所起的作用。Bt棉花是一种自2002年开始在印度市场上销售的转基因棉花。使用独特的数据集和经验方法，我发现农民似乎完全是从村里一小群“进步的”农民的实验中学到的，也就是说，被其他(“常规”)农民采用并不被认为是关于这项技术的有用信息来源。其次，我发现了社会压力的证据，这种压力源于这样一种信念，即Bt棉可能对环境和牲畜有害，这阻碍了人们采用Bt棉，至少在一段时间内是这样。凝胶码：03、Q1。
Abstract This paper examines the role that social networks play in the adoption process of Bacillus thurigiensis (Bt) cotton, a type of genetically engineered cotton that has been available on the Indian market since 2002. Using a unique dataset and empirical methodology, I find that farmers appeared to have exclusively learned from the experimentation of a small set of “progressive” farmers in the village, that is, adoption by other (“regular”) farmers was not considered a useful source of information about the technology. Second, I find evidence of social pressures, originating from the belief that Bt cotton might be hazardous to the environment and livestock, which inhibited adoption, at least for some time.
