针对能源效率问题的中国地区聚类

Energy Efficiency Based Regional Cluster Analysis of China

传统区域划分方式多从地理区位的角度出发,缺乏对拟解决问题的针对性。中国幅员辽阔,各地区资源条件、发展状况以及能源效率水平差异悬殊,对各地区进行更为科学的聚类分组将有利于节能潜力的合理挖掘,同时可为针对性政策的制定提供理论依据。针对能源效率问题对中国30个省级地区进行聚类分析,并对新分组后各组内地区能源强度变异系数的收敛性进行检验。根据选取的指标,将30个地区分为6组,重新分组后,各组均具有明显的特征;能源强度表现出了显著的收敛性;能源强度变异系数曲线总体上呈倒U型变化规律,说明在组内能效差异水平到达峰值后,组内各地区的能源强度开始进入收敛期。

The conventional region classification mainly based on geographical location, which is lack of pertinence of the problems to be solved. Target on energy efficiency issues of China, this paper re-clustered 30 regions and examined the energy intensity convergence of each group by coefficient of variation. The study shows that： the clustering results of energy efficiency indicate that the 30 regions of China are divided into six clusters and each has its own significant characteristics; the energy intensity convergence of intra-group was stronger compared with traditional grouping; the curve of coefficient of variation was like to the shape of ＂Inverse-U＇, which indicated that after the difference of the intra- group energy efficiency had reached a peak, the energy intensity will get into stable convergence.
