农户对转基因生物技术的认知及采纳行为实证研究——以种植转基因Bt抗虫棉为例

Empirical Research on Farmers'Cognition of Trans-genic Biotechnology and Adoption Behavior——Planting Trans-genic Bt Cotton as an Example

本文以安徽省327个农户为研究对象,运用Heckman选择模型对农户关于转基因生物技术的认知及采纳行为进行了实证分析。研究结果表明,户主文化程度、社会资本、与村民交流的频率、国家良种补贴项目县、参加转基因生物技术培训等因素显著促进农户对转基因生物技术的认知,而户主年龄对农户的认知呈负面影响。显著正向影响农户种植转基因Bt抗虫棉的因素主要有户主文化程度、社会资本、与村民交流的频率、国家良种补贴项目县、参加转基因生物技术培训、棉铃虫发生的严重程度,而Bt抗虫棉种子价格对农户种植抗虫棉呈负面影响。最后,根据实证研究结果提出了相应的政策建议。

This study, using the Heckman selection model, analyses empirically farmers＇cognition of trans-genic biotech- nology and adoption behavior on basis of 327 farmers＇data in Anhui Province, The result shows that the education level, social capital, exchanging ideas with other villagers, the county of national seed subsidy program, participating in training are more significant in promoting farmers＇cognition of trans-genic biotechnology; but the age presents a negative role. The significant positive impacts on farmers＇planting trans-genic Bt cotton are the education level, social capital, exchanging ideas with other villagers, the county of national seed subsidy program, participating in training, bollworm occurrence degree, but the prices of Bt cotton seed presents a negative role. Finally, the study puts forward some policy recommendations.
