社会网络、风险偏好与节水抗旱稻技术采用行为研究——基于Heckman样本选择模型的实证分析

【目的】探索影响农户节水抗旱稻技术采用决策和采用时间的因素,为节水抗旱稻技术宣传推广提供借鉴。【方法】基于社会网络、风险偏好视角,运用Heckman样本选择模型作为本研究的研究方法,实证分析了社会网络、风险偏好这两个核心变量对农户节水抗旱稻技术在采用决策以及采用时间这两个方面的影响。【结果】①社会网络、风险偏好对节水抗旱稻技术采用决策与采用时间均有显著影响,其中社会网络是正向的,风险偏好是负向的。②在社会网络4个维度中,网络信任、网络学习、网络互动3个维度对农户节水抗旱稻技术采用决策和采用时间具有显著的正向影响,网络互惠则是正向不显著。③农户节水抗旱稻技术采用决策和采用时间还受到风险偏好类型、技术培训参与、技术宣传力度、技术了解情况等控制变量的影响。【结论】注重农户社会网络建设与培育,减轻风险厌恶型农户对节水抗旱稻技术采用可能存在的风险感知,促使其接纳节水抗旱稻技术,提高节水抗旱稻技术的采用率和采用时间。

Development Prospect and Strategies of Water-saving and Drought-resistance Rice

Water-saving and drought-resistance upland rice has become a preferable choice for cotton farmlands ready for changing crops or paddy fields with water in short,because simplified and mechanical cultivation can be applied for the rice varieties of drought resistance and high yield.At present,it has been applied with an area of 400 000 hm2 in Hunan Province and the area continues growing.The research bred and introduced the relevant cultivation technology standard applicable to local water-saving and drought-resistance rice varieties in order to improve farmer＇s benefits.
