摘　　要：基于跨期农业技术的高风险特征,阐释了农户风险偏好对跨期农业技术采纳行为的影响机理.根据川渝柑橘主产区433户桔农的调查数据,借助IVProbit和IVTobit模型实证检验了农户风险偏好对柑橘高接换种技术采纳行为的差异化影响,以及技能水平对风险偏好影响作用的调节效应.结果表明:①样本农户风险规避程度普遍较高,而技能水平参差不齐,高接换种技术采纳行为偏保守,采纳概率和采纳强度较低.②农户风险偏好、技能水平的异质性导致了高接换种技术采纳行为决策的较大差异,农户风险规避程度对高接换种技术采纳行为有显著的负向影响,而农户技能水平对高接换种技术采纳行为有显著的正向影响.③农户技能水平有助于缓解风险规避对高接换种技术采纳的抑制,相对于技能水平较低的情况,在技能水平较高的条件下农户风险规避心理对高接换种采纳行为的负向影响明显减弱.较高的技能水平能够成为引导风险规避型农户积极采纳高接换种技术的有效介质.Based on the high-risk characteristics of intertemporal agricultural technology,this paper explains the influence mechanism of farmers􀆳risk preference on intertemporal agricultural technology adoption behavior.According to the survey data of 433 citrus farmers in Sichuan and Chongqing,this paper empirically tested the impact of farmers􀆳risk preference on the adoption of top grafting technology and the moderating effect of planting skill on impact of risk preference by using IVProbit and IVTobit models.The results show that:①The degree of risk aversion of the sample farmers is generally high,but the skill level is uneven.The adoption behavior of top grafting technology is conservative,and the adoption probability and intensity are low.②The heterogeneity of farmers􀆳risk preference and planting skill has led to the large difference in the decision-making of top grafting technology adoption.The degree of farmers􀆳risk aversion has a significant negative impact on technology adoption behavior,while farmers􀆳skill level has a significant positive impact on the technology adoption behavior.③The planting skill of farmers helps to alleviate the inhibition of risk aversion on the adoption of top grafting technology.Compared with the situation of low skill level,the negative impact of farmers􀆳risk aversion on the adoption behavior of top grafting technology is significantly weakened under the condition of high skill level.High planting skill level can be an effective medium to guide risk-averse farmers to actively adopt top grafting technology.
