社会资本对农户采纳生态农业技术决策行为的影响——以稻虾共养技术为例

Influence of social capital on farmers’adoption of ecological agriculture technology decision-making behavior:Taking rice and shrimp co-culture technology as an example

基于湖北、湖南和安徽省共980份农户的微观调研数据和Heckman样本选择模型,从采纳行为和采纳程度两个方面实证分析了社会资本对农户采纳稻虾共养技术决策行为的影响。结果表明:社会资本对农户技术采纳行为和采纳程度均有显著的正向影响。1)社会参与对农户技术采纳行为和采纳程度均有显著的正向影响,但社会网络对农户技术采纳行为和采纳程度的影响效果不显著;2)社会信任对农户技术采纳行为和采纳程度的影响效果存在差异,即信任周围邻居传播的技术信息显著正向影响农户技术采纳行为和采纳程度,而信任网络电视等大众传媒传播的技术信息仅显著正向影响农户技术采纳行为;3)从不同经营规模探究发现,对于规模户而言,参与技术推广活动、信任农技推广单位传播的技术信息对其技术采纳行为有显著的正向影响。对于小农户而言,参与村集体选举活动、信任周围邻居和网络电视等大众传媒传播的技术信息对其技术采纳行为有显著的正向影响。因此,在未来技术推广过程中应更加重视社会资本对农户技术采纳决策的影响。

Based on the micro-research data of 980rural households in Hubei,Hunan and Anhui Province,the impact of social capital on farmers’adoption of rice-shrimp co-culture technology decision-making behavior was empirically analyzed by using Heckman sample selection model from the aspects of adoption behavior and adoption degree.The results showed that social capital had a significant positive impact on farmers’technology adoption and adoption:1)Social participation had a significant positive impact on farmers’technology adoption behavior and adoption level,but the effect of social network on farmers’technology adoption behavior and adoption degree was not significant;2)The effects of social trust to farmer technology adoption behavior and adoption degree were different.The technical information of trusting neighbors’communication was significantly positively affecting the adoption and adoption of farmers’technology.The technical information of mass media such as Internet TV is only positively affecting the adoption of technology Behavior;3)From the view point of different business scales,it is found that for large-scale households,the technical information involved in technology promotion activities and trusting agricultural technology promotion units had a significant positive impact on their technology adoption behavior.For small-scale households,the technical information of mass media participation in village collective election activities,trusting neighbors and Internet TV had a significant positive impact on their technology adoption behavior.In the future technology promotion process,more attention should be paid to the impact of social capital on farmers’technology adoption decisions.
