Influencing factors of urban building energy consumption in Chongqing based on STIRPAT model

For the quantitative research on the influencing factors of urban building energy consumption in Chongqing from 2005 to 2014, establishes a mathematical model of the factors affecting the energy consumption, analyses the model by least square method and ridge regression analysis based on STIRPAT model, and validates the model under eight scenarios. The results indicate that the influencing factors of energy consumption from 2005 to 2014 in accordance with their influence degree can be divided into five parts: consumption level of urban residents (28.6%), building area per capita (23.1%), the tertiary industry development (21.9%), rate of urbanization (20.7%) and total population (5.8%).
