摘要
采用改进的最大"前沿面集"非期望SBM模型系统的评价了1997~2011年中国28个省份的全要素能源效率,并利用经济—地理距离权重改进的空间计量模型对省际全要素能源效率的空间收敛性进行了实证研究。结果表明:中国整体及各省的全要素能源效率较低,节能潜力为25%~50%;省际全要素能源效率自东向西逐渐减小,并呈现东部、中部和西部的空间聚集分布特点;省际全要素能源效率的空间相关性在增强,且存在空间溢出效应;各省份全要素能源效率的差距正在逐渐减小,绝对收敛速度为1.49%;影响因素中,研发投入和开放程度与全要素能源效率显著正相关,而产业结构和制度变量则对全要素能源效率产生不利的影响。
This paper evaluate the total factor energy efficiency of 28 provinces in China from 1996 to 2010through using the improved largest 'frontier set' undesirable SBM model,uses economic-geographic distance weight to improve the spatial metrology model,which is applied to do the empirical research about the spatial convergence of provincial total factor energy efficiency.Results show that:(1)total factor energy efficiency of China and all the provinces are low,saving potential of energy is about 25%to 50%;(2)provincial total factor energy efficiency decreases gradually from east to west,and appeares spatial distribution characteristic in eastern,central and western;(3)spatial correlation of provincial total factor energy efficiency is enhancing,and spatial spillover effect is existent;(4)the gap of provincial total factor energy efficiency is gradually reduced,with the absolute convergence rate being 1.49%;(5)as to the influence factors,R&D investment,opening degree is significantly positively related to energy efficiency,influence of industrial structure and system variable on energy efficiency is adverse.
