Sectoral comparison of electricity-saving potentials in China:An analysis based on provincial input-output tables

摘要

China's electricity generation is mainly dependent on fossil fuel.Advocating electricity conservation in different sectors and regions is certainly important for reducing energy-related CO2 emissions and other pollutants.The aim of this paper is to identify the sectors as well as the economic regions with higher electricity-saving potentials.We propose two indicators for measuring the electricity-saving potential based on the input-output method,called technical elasticity coefficient(TEC)and price sensitivity coefficient(PSC)respectively.The proposed approach is used to analyse the electricity-saving potentials of 20 sectors in different provinces of China in 2007.Our empirical results show that Mechanical industry has the largest electricity-saving potential.From the perspective of economic regions,the east region takes the first place.An electricity forward correlation coefficient(EFC)is also presented to examine the relationship between electricity-saving potential of one sector and its power consumption in our study.
