【摘要】 以中国国民经济用电单耗为研究对象,采用描述性统计法和因素分解法相结合的方法,实证分析1990-2007年间中国GDP用电单耗和三次产业用电单耗的变化趋势,并对影响用电单耗变化的结构因素和效率因素的贡献值和贡献份额进行定量计算,结果表明:GDP用电单耗的下降主要是由于电源使用效率的提高引起的,其中二产用电单耗的变化是决定性因素。更多还原

【Abstract】 The article tries to take the Chinese GDP electricity power consumption intensity as the research object,adopts the combinative method including the descriptive statistic method and Logarithmic Mean Weight Divisia Method,in demonstrating way analyzes the change trends of Chinese GDP electricity power consumption intensity and electricity power consumption intensity of the three industries during 1990-2007 and carries out the quantificational calculation on the main influence factors such as the structure factor and the efficiency factor.The research results show that the decrease of GDP electricity power intensity is resulted from the improvement of power application efficiency,in which the change of electricity power consumption intensity for the second industry is the decisive influence factor.更多还原
