城镇化对能源强度的影响及区域差异分析——基于空间滞后模型研究

The Impact of Urbanization on Energy Intensity and Analysis of Regional Differences Based on Spatial Lag Model

基于空间滞后模型(SLM)测算了我国2004—2016年30个省份的能源强度和城镇化水平,并从地理特征和社会经济特征两方面构建了三种空间权重矩阵,分析了城镇化对我国不同区域能源强度的影响。研究结果表明:我国城镇化水平和能源强度均具有显著的空间溢出效应,并且呈现正相关关系;在我国四个区域中,城镇化水平与能源强度均表现为负相关关系,中部地区影响程度最强,西部和东北地区次之,东部地区最弱。

Based on spatial lag model, the paper calculates the energy intensity and the level of urbanization of 30 provinces in China from 2004 to 2016, and the three spatial weight matrix is constructed from two aspects of geographical characteristics and social and economic characteristics, and analyses the influence of urbanization of our country’s energy intensity in different areas of the impact. The results show that China’s urbanization level and energy intensity have significant spatial spillover effects and present positive correlation. In four areas of our country, the level of urbanization has a negative correlation with energy intensity. The central region has the strongest impact, followed by the western and northeastern regions, and the eastern region is the weakest.
