Calculation and decomposition of regional household energy consumption in China: based on perspectives of urbanization and residents' consumption

摘要

Demographic urbanization caused great changes in scale of residents' consumption and residents' lifestyle and then impacted changes of regional household energy consumption.This paper expanded Logarithmic Mean Decomposition Index method through introducing variables of urbanization and residential consumption into the model.It also analyzed the influences of six factors as energy structure, energy intensity, population scale, urbanization, residential consumption, and consumption inhibit on regional household energy consumption.Results showed that in 2003-2012, impact of urbanization on regional household energy consumption of Chinese three areas was significantly higher than population size.The “population gathered in eastern region” phenomenon caused eastern region getting the largest population scale effect.Driving force of residential consumption on regional household energy consumption was much higher than the other five effects.Due to the comparative advantage of residential consumption compared with government consumption, investment, and net export, the decrease of consumption ratio promoted the growth of regional household energy consumption.Energy intensity in Chinese three regions kept reducing in 2003-2012.The progress of energy utilization technology slowed the growth of regional household energy consumption, and energy intensity effect was most significant in the central region.
