转基因抗虫棉是中国商业化应用最成功的转基因作物,已有许多研究对转基因棉花种植的成本效益和农户生产决策的影响因素进行了深入分析,但对其具体推广过程缺乏足够了解。通过小组访谈和创新树的分析方法,以转基因抗虫棉为例,对转基因生物技术在我国的推广和传播途径开展了研究。研究发现,种业公司转基因作物种子的生产能力直接影响转基因作物的初始规模,来自政府研究机构和种业公司的技术推广者在转基因生物技术的扩散过程中都起着重要作用,公共农技推广服务对于宣传相关信息和知识尤为重要,社会资本也有助于转基因抗虫棉在中国的快速传播和采用。研究结论对推进我国公共农技推广体系改革、完善多元社会化服务主体协作及生物技术研发具有重要启示作用。
Transgenic insect-resistant cotton is the most successful transgenic crop for commercialization in China. There are many studies on the cost-benefit of transgenic cotton planting and the influencing factors of farmers’ decision-making. However, there is not enough understanding about the specific promotion process. Through the group interview and innovative tree analysis methods, taking transgenic cotton as an example, the promotion and transmission of GMOs in China were studied. The study found that the seed production capacity of seed companies directly affects the initial size of genetically modified crops. Technology promoters from government research institutes and seed companies all play an important role in the diffusion of GMOs. Public agricultural technology promotion Services are particularly important for the promotion of relevant information and knowledge, and social capital also contributes to the rapid spread and adoption of GM cotton in China. The conclusions of the study have an important enlightenment on promoting the reform of public agricultural technology extension system, improving the coordination of multiple social service subjects and biotechnology research and development.
