中文摘要:
      本文为比较不同类别信息对淡水养殖户采纳两型生产技术的影响效应,在对农户采纳技术行为进行理论分析的基础上,构建以社会网络作为工具变量的回归模型。结果表明,(1) ○1获取技术信息对农户采纳两型农业技术有显著的促进作用,在不考虑技术信息内生性的情况下,获取技术信息的影响会被低估;(2)○2不同类别信息对农户采纳两型农业技术的影响程度不同,获取技术使用信息对农户采纳两型农业技术的影响程度大于获取技术市场信息。在使用信息中,操作信息比经验信息对农户采纳技术的促进作用更大;在市场信息中,价格信息比质量信息对农户采纳技术的促进作用更大。
英文摘要:
      In order to compare the impacts of different information on the adoption of resource-efficient and environmental friendly technology by freshwater farmers, a regression model with social network as the instrumental variable is constructed based on the theoretical analysis of farmers' adoption behavior. It is shown that, (1) Obtaining technical information significantly promotes the adoption of resource-efficient and environmental friendly technology,the impact is to be underestimated without considering the endogeneity of technical information; (2) Different information has different impacts on the adoption of resource-efficient and environmental friendly technology. Obtaining using information has greater impact on farmers’ adoption of resource-efficient and environmental friendly technology than obtaining market information. In the using information, operation information has a greater impact on adopting technology than experience information. In the market information, price information has a greater impact on adopting technology than quality information.
