基于不同权重矩阵的我国能源效率空间效应研究

本文根据经济活动的空间相关性，测算我国各省的能源效率值，建立动态空间杜宾模型，并分解为直接效应和间接效应，分析影响我国省际能源效率的因素。结果表明：我国省际能源效率存在正的空间相关性和溢出效应，在不同空间权重矩阵下溢出效应存在差异性。经济发展水平、产业结构、能源消费结构和对外开放程度对能源效率存在显著的正影响，要素禀赋对能源效率存在显著的负影响。

Spatial Effect Research of the Provincial Energy Efficiency inChina Based on Different Weight Matrix

According to the spatial effect of economic activities,this paper estimates the energy efficiency of the provinces in China,then establishes the dynamic Spatial Dur bin Model,which is decomposed into the direct effect and the spillover effect,an alyzes the factors affecting provincial energy efficiency in China.Results show that the provincial energy efficiency has an obviously positive spatial correlat ion and spillover effect,the spillover effect is different from spatial weight m atrix.Economic development and the industrial structure and opening to the outsi de world and energy consumption structure have a significant positive impact on energy efficiency,and the factor endowment has a significant negative impact on energy efficiency.
