This paper analyses spatial dependence and determinants of the New Zealand dairy farmers' adoption of best management practices to protect water quality. A Bayesian spatial durbin probit model is used to survey data collected from farmers in the Waikato region of New Zealand. The results show that farmers located near each other exhibit similar choice behaviour, indicating the importance of farmer interactions in adoption decisions. The results also address that information acquisition is the most important determinant of farmers' adoption of best management practices. Financial problems are considered a significant barrier to adopting best management practices. Overall, the existence of distance decay effect and spatial dependence in farmers' adoption decisions highlights the importance of accounting for spatial effects in farmers' decision-making, which emerges as crucial to the formulation of sustainable agriculture policy.
本文分析了新西兰奶农采用最佳管理实践以保护水质的空间依赖性及其决定因素。运用贝叶斯空间杜宾概率模型对从新西兰怀卡托地区奶农收集的数据进行了调查。结果表明，相邻的奶农表现出相似的选择行为，这表明奶农之间的互动在采用决策中具有重要性。结果还表明，信息获取是奶农采用最佳管理实践的最重要决定因素。财务问题被认为是采用最佳管理实践的重大障碍。总体而言，奶农采用决策中距离衰减效应和空间依赖性的存在凸显了在奶农决策过程中考虑空间效应的重要性，这对于制定可持续农业政策至关重要。
