Abstract: Abstract: Based on the panel data of 30 provinces in China from 2000 to 2016, the fixed-effect panel model was used to empirically study the influencing factors of energy intensity. The research results show that the level of economic development has an inhibitory effect on energy intensity. The level of urbanization and the structure of energy consumption have a positive effect on energy intensity. There is an inverted “U” type nonlinear relationship between i advanced industrial structure and energy intensity, and As of 2016, the industrialization level of nine provinces and cities such as Tianjin and Inner Mongolia is lower than the inflection point value, which indicates that improving the level of advanced industrial structure in these provinces can further promote the the reduction of energy intensity. Finally, based on the results of estimation and analysis, countermeasures and suggestions for reducing energy intensity are proposed.
