The invention discloses a method for quantitatively comparing and analyzing morphological characteristics of city energy consumption. The method comprises the following steps of: construction of a city energy comparison system; data acquisition; modeling and quantitative calculation of city energy; and comparison and analysis of the city energy. The method is based on the consumption link of the city energy, and is used for multi-angularly and comprehensively comparing and analyzing the consumption characteristics of the city energy. According to the method, the city energy comparison system is firstly established; the consumption characteristics of the city energy are investigated from four aspects through modeling and quantitative calculation; and finally, the weight and evaluation criterions of each aspect are determined by utilizing a Delphi method, so as to finally obtain a comprehensive comparative analysis result of the city energy. According to the method, the comparison and analysis result can be used for reflecting the consumption characteristics and advantages of each energy from a plurality of aspects, assistance is provided for seeking an optimum utilization manner of the city energy, contribution is provided for improving the using efficiency of the city energy and decrease the city environment pollution, and significance is provided for enhancing the energy consumption consciousness of the country and boosting the change of an energy consumption manner of the country.
