文中利用甘肃省张掖地区的农户调查资料,运用二元Probit回归模型实证分析外部冲击和社会网络对农户节水灌溉技术采用的影响,并引入交互项检验社会网络对外部冲击的缓解作用。研究结果表明:外部冲击对农户节水灌溉技术采用有负向影响,而社会网络对节水灌溉技术采用有正向影响;同时,社会网络能够缓解外部冲击的抑制作用。除上述影响因素以外,农户节水灌溉技术采用还受到性别、年龄、受教育程度、职务、健康状况和家庭年收入的影响。
Based on the survey data of farmers in Zhangye Prefecture, Gansu Province, this paper uses two-factor Probit regression model to empirically analyze the impacts of external shocks and social networks on the adoption of water-saving irrigation techniques for rural households. The paper also uses interaction terms to test the mitigation effect of social networks on external shocks. The results show that external impact has a negative impact on the adoption of water-saving irrigation technology for farmers, while social networks have a positive impact on the adoption of water-saving irrigation technology. At the same time, social networks can alleviate the inhibitory effect of external shocks. In addition to the above factors, the adoption of water-saving irrigation techniques by farmers is also affected by gender, age, education level, job title, health status and annual household income.
