中文摘要：空间计量经济学是经济学研究的热门领域,但空间权重矩阵设定的主观性一直富有争议.在系统梳理现有空间权重矩阵构造方式的基础上,针对现行设定方法的缺陷,提出一种基于引力模型的非对称空间权重矩阵构建方法,并应用于中国全要素生产率"结构黑箱"的分解.构建基于非对称引力权重矩阵的城市面板空间计量模型,并通过对比分析普通经济距离空间权重矩阵和引力空间权重矩阵的估计结果发现,非对称引力空间权重矩阵在空间相关性检验及空间计量模型拟合优度方面,均表现出良好的性能.

外文标题：Construction of An Asymmetric Spatial Weight Matrix Based on Gravity Model——Empirical Testing from the Perspective of Regional Total Factor Productivity

外文摘要：Spatial econometrics is a popular field in economic research,but the subjectivity involved in specifying spatial weight matrices has long been a topic of debate.The article systematically reviewed existing methods for constructing spatial weight matrices,and addressed the shortcomings of current approaches by proposing a novel method for constructing an asymmetric spatial weight matrix based on the gravity model.This new approach was then applied to decompose the"structural black box"of total factor productivity in China.The paper constructed a spatial econometric model for urban panel data based on an asymmetric gravity-weight matrix.Through the comparative analysis of the estimation results obtained using conventional economic distance matrices and the proposed gravity-based spatial weight matrices,we found that the asymmetric gravity spatial weight matrix exhibited superior performance in spatial correlation tests and the goodness-of-fit of spatial econometric models.
