摘要(Abstract):
为探寻中国电力消费的影响因素,提出了基于LMDI(对数平均迪氏分解)的电力消费分解模型。将经济效应、结构效应和强度效应作为电力消费的影响因素,基于2006—2019年中国31个省份和3个产业的电力消费数据,分别从省域和产业2个层面进行实证研究及全国电力消费分解的比较分析。根据LMDI模型的计算结果进行K-means聚类分析,提出优化中国电力消费结构的建议。
To explore the influencing factors of China's electricity consumption, an electricity consumption decomposition model based on the LMDI(Logarithmic Mean Divisia Index) is proposed. Taking the economic effect, structural effect and intensity effect as influencing factors of electricity consumption and in the light of the electricity consumption data from 31 provinces and 3 industries in China from the year 2006 to 2019, this paper makes an empirical study from the provincial and industrial levels respectively and comparative analysis on the decomposition of electricity consumption in China. Finally, according to the calculation results of the LMDI model, K-means clustering analysis is carried out, and suggestions for optimizing China's electricity consumption structure are put forward.
