Research On The Decomposition Of Regional Energy Efficiency In China Based On IPAT-LMDI Model

In modern society,energy efficiency has become an important factor affecting the national economic growth and regional energy consumption.The research on energy efficiency has been widely concerned.Because of the geographical location,resource endowment and other factors,the regional economic development level and the corresponding energy efficiency in the energy distribution intensive areas are very low.Regional economic development level presents a certain regional characteristics.A large number of energy consumption improves the regional economic development based on the advantages of energy distribution in various regions,leading to a lot of waste of energy.Therefore,it is of great practical significance to study influence factors and the differences of the regional energy efficiency,and to analyze the regional differences of energy efficiency for formulating scientific and rational energy policy.This paper first analyzes the status quo and the changes about energy consumption in China.Energy efficiency in the eastern provinces is significantly higher than the central and western regions according to the change trend.Then,the paper analyzes influence factors of energy efficiency from 30 provinces of China during 2008-2012 based on IPAT model and LMDI decomposition model.We divide China into four regions(the Beijing-Tianjin-Hebei region,the Yangtze Economic Belt,Silk Road Economic Belt,21 st Century Maritime Silk Road)to make the further analysis of the influence factors and the differences in regional energy efficiency.Energy efficiency in this study is decomposed into carbon productivity effect,carbon emission coefficient effect,energy structure effect,energy intensity effect,economic output effect,the reciprocal of per capita energy consumption effect.The study indicates that the regional energy efficiency has great difference and the influencing factors of regional energy efficiency have different effect sizes.Overall,the economic output effect has the greatest positive driving effect on China’s energy efficiency,followed by the carbon productivity effect,energy structure effect,carbon emission coefficient effect.At the same time,energy intensity effect and the reciprocal of per capita energy consumption effect have negative effect on energy efficiency.Finally,the paper stressed that accelerating the industrial structure adjustment,optimizing energy consumption structure and developing high efficiency technology have important theoretical and practical significance on the implementation of low-carbon economic development strategy.
