Spatial dependence in agricultural land prices: does it exist?
研究了农业土地价格特征模型中的空间依赖性与函数形式选择之间的权衡，发现不恰当的函数形式可能导致虚假的空间依赖性，而使用半参数方法后未检测到空间依赖性。
Abstract Trade‐offs arise between spatial dependence and choice of functional form in agricultural land price hedonic models. We discuss these trade‐offs and how they can create spurious spatial dependence. Using a land sales dataset with apparent spatial dependence, we implement a semiparametric approach avoiding potential problems with the functional form. The results show that in addition to being nonlinear, the impacts are also characterized by significance thresholds that are difficult to capture in a parametric model. More importantly, we fail to detect any spatial dependence demonstrating that inappropriate functional form can indeed be responsible for finding spatial dependence in hedonic models.
