中国能源足迹的测度及区域差异分析

Measurement of China’s Energy Footprint and Analysis of Regional Differences

文章使用能源生态足迹测算方法,对中国1995-2016年的能源足迹进行了测算,结果表明我国能源足迹呈上升趋势,特别是在2001-2011年间,能源足迹呈现显著的区域差异。并采用Dagum基尼系数,从区域内、区域间、超变密度三方面对能源足迹区域差异进行分解,结果表明能源生态足迹区域内差异呈现"东-西-东北-中"递减趋势;东部和西部地区间的差异最大;地区间差异是影响能源足迹区域差异的最主要因素,其次为超变密度差异因素,区域内差异因素影响最小。

This paper uses the method of energy ecological footprint measurement to calculate China’s energy footprint from1995 to 2016.The results show that China’s energy footprint is on the rise,and especially in the period from 2001 to 2011,the energy footprint shows a significant regional difference.And then,the paper uses the Dagum Gini coefficient to decompose the regional difference of energy footprint from three aspects of intraregional,interregional and hyper-variable density.The decomposition results show that the difference in the energy ecological footprint presents an"east-west-northeast-central"gradual declining trend,that the differences between the eastern and western regions are the greatest,and that the interregional difference is the most important factor affecting the regional difference of energy footprint,followed by the difference of hyper-variable density,with the intraregional difference to be the least affecting factor.
