Dynamic Environmental Efficiency Assessment for Electric Power Industries:Evidence from OECD and BRIC Countries
Electric power industry is the largest source of carbon emissions in the world.As most of the power generated is consumed domestically,it is of great significance to objectively evaluate the environmental efficiencies of electric power industries in different countries and their carbon reduction efforts for climate change mitigation and international reduction protocol formulation.Taking the power generated and IVA(Industrial Value Added)as desirable outputs and carbon emissions as undesirable output,this paper adopts the Malmquist index,which is based on SBM‐DEA(slack based measure‐data envelopment analysis)model,to investigate the dynamic environmental TFP(total factor productivity)of electric power industries of 26 OECD(Organization for Economic Cooperation and Development)and BRIC(Brazil,Russia Federation,India and China)countries from 2000 to 2008.Furthermore,we employ the Tobit regression to analyze the influence of related factors on environmental total factor productivity index and its decompositions.The empirical results indicate that the environmental Malmquist provides a good perspective for timely reaching an agreement applicable to most countries.In addition,fuel structure change and technological innovation are the man driving forces to promote low-carbon development.Both GDP per capital and GDP growth play negative roles in improving environmental Malmquist index.Therefore,only by taking reduction efforts as well as current emission status and affordability into consideration can different countries reach a binding climate change mitigation agreement.
