摘要
采用泰尔指数分解和马尔科夫链探析1992-2015年全球电力消费的空间差异演化特征,并将其分解为第二产业、第三产业和居民生活用电来对导致全球电力消费空间差异的原因进行分析.结果表明:全球电力消费水平空间差异不断缩小,六大区域间的差异是导致空间不均衡的主导力量,但六大区域内部电力消费差异整体呈缩小趋势;全球第三产业电力消费差距最大,居民生活次之,第二产业最小;各国第三产业和居民生活电力消费的非均衡是引起全球电力消费水平空间差异的主要因素;全球电力消费存在俱乐部趋同现象,各国电力消费水平类型在空间转移上存在较小差异,中间阶层数量有所增加.
By the Thiel index method and Markov chains,this paper analyzes the evolution characteristics of spatial difference of the world electricity consumption from 1992 to 2015.And the electricity consumption is divided into the secondary industry,the tertiary industry and residents living to further analyze the causes of global electricity consumption spatial differences.The conclusion is as follows:From 1992 to 2015,the spatial difference of global electricity consumption level has been shrinking.The six regions’ interregional difference was the leading force that caused inequality of global electricity consumption,but intraregional difference as a whole showed a narrowing trend.Among three dimensions,the difference of electricity consumption in the tertiary industry is the largest,followed by the difference in residents living,and the difference in the secondary industry is the smallest.And the inequality of the tertiary industry and household electricity consumption was the main factor for the inequality of spatial difference of global electricity consumption level.There were "convergence clubs"in global electricity consumption,which were small differences in the spatial transfer of electricity consumption levels types in different countries in the world,and the number of middle classes has increased.
