The Stady On Relationship Between Economic Growth And Electricity Consumption In Beijing

Accompanying with rapid economic development, increasing society livingcondition, increasing high-speed energy consumption, and much more demand forelectricity, the issue of supply and demand has draw more attention. In "EleventhFive-Year" period, although Beijing successfully reduces energy consumption per unitwith the help of optimizing industrial structure, the total energy consumption is stillfar from the control objectives, which are forcing Beijing to explore the internalrelationship between energy consumption and economic growth, and to explore thesustainable development way of ensuring economic growth with lower energyconsumption.Selecting the data about economic growth and electricity consumption in1980-2010, after analyzing on the current situation and recent trend of them, thispaper develops the cointegration test depending on passing the stationary test, thusfinds the long-term relationship between them. And then the Granger causality test isdone, and the causality relationship from electricity consumption to economic growthin Beijing is proved. Further the electricity consumption intensity by factordecomposition method is analyzed and both structure of industry and technologyimprovement working together to reduce electricity consumption intensity in Beijing,in which the reduction of industrial electricity consumption intensity plays a majorrole, is proved. When testing the significance of parameters in model, bootstrapmethod is used to full use the information of sample in order to get more accurate andreliable results than the traditional method. Finally, basing on the empirical results thecharacteristics of the economic growth and electricity development are revealed, andthus suggestions about electricity saving are provided.
