A regression model is called a spatial error model when spatial autocorrelation is present in the disturbance. A spatial error model is classified into one of two types on the basis of the method of specification of spatial autocorrelation. The first type is defined using a correlation function, which is a device to specify the autocorrelation in a direct manner, whereas the second type is defined using a weight matrix, which is a device to specify it in an indirect manner. The purpose of the present study is to evaluate the performance of spatial error models using experimental and empirical approaches. As errors cannot be assumed to be absent in any specification, choosing a relatively well-performing model is a good policy in order to allow for such errors. Methodological issues are addressed with regard to both estimation and prediction, and some results are presented that support the combined use of the two types of models.

当扰动中存在空间自相关时，回归模型称为空间误差模型。根据空间自相关规范的方法，将空间误差模型分为两种类型之一。第一类型是使用相关函数来定义的，其是以直接方式指定自相关的装置，而第二类型是使用权重矩阵来定义的，其是以间接方式指定自相关的装置。本研究的目的是使用实验和经验方法评估空间误差模型的性能。由于不能假设任何规范中都不存在错误，因此选择性能相对良好的模型是允许出现此类错误的一个好策略。解决了估计和预测方面的方法问题，并提出了一些支持两种模型联合使用的结果。
