基于经济内循环的空间权重矩阵构建OACHSSCD

Spatial econometrics reveals the law of economic development among spatial units by constructing a spatial weight matrix.Based on the interregional input-output table from the perspective of domestic value chain,this paper expounds the mea-surement method of intra-provincial economic circulation under the comprehensive dimension,and then constructs the spatial weight matrix of economic domestic circulation.Finally,on this basis,the paper uses a variety of spatial weight matrix for parame-ter estimation and comparative analysis.The results show that the spatial weight matrix constructed by using the economic internal circulation has demonstrated good accuracy and effectiveness in the parameter estimation of the model,and can can better reflect the actual economic linkages between the spatial units.In addition,this weight matrix also shows a stronger ability to identify spa-tial correlations,able to accurately capture the interactions and dependencies between different spatial units.
