发布时间:2019-04-19 10:15
【摘要】:空间权重矩阵的构造一直是地理学、空间计量经济学和医学等领域中的难点和热点问题。权重矩阵合适与否,将直接关系到模型的最终估计结果。文章基于渗透搜索算法,通过局部Moran′I的比较,得到新的"邻接"关系区域,并结合基于经济距离的权重构造出新的权重矩阵。
[Abstract]:The construction of spatial weight matrix has always been a difficult and hot issue in the fields of geography, spatial econometrics and medicine. Whether the weight matrix is suitable or not will be directly related to the final estimation result of the model. Based on the penetration search algorithm, a new "adjacency" relation region is obtained by comparing the local Moran'I, and a new weight matrix is constructed by combining the weights based on economic distance.
