Empirical Research On China’s Regional Total Factor Electrical Energy Consumption Efficiency

Electrical energy is an important support for China’s economic development, itas an end-use energy is more and more important in numerous energy. With theeconomic of China is developing rapidly, energy problem is more and more serious.Saving energy and improving the efficiency of electric energy are undoub tedly keyway to dealing with energy challenge. Therefore, studying of regional electricityenergy consumption efficiency, researching the trend of region’s energy consump-tion efficiency and comparing the region’s efficient difference have important theo-retical and practical significance.This paper presents the total factor electric energy consumption efficiency onthe basis of the theoretical concept of the energy effic iency, and then analyzes thecurrent situation of electrical energy consumption. This paper analysis the region’stotal factor electrical energy consumption efficiency from static and dynamic mainlyuses the three-stage DEA model and Malmquist productivity index model. Specificideas are as follows: Firstly, calculating the electrical energy consumption efficiencyof29provinces, dividing29provinces into four types according to energy efficiency,making mean and coeffic ient of variation analys is for three regions, making clusteranalysis for the29provinces according to high efficient， medium effic ient or inef-ficient. Secondly, analys ising the total factor electrical energy consumption effi-ciency dynamically with three-stage DEA model and Malmquist productivity index.Thirdly, researching the gap of inter-regional electric energy consumption efficiencyusing the convergence test.Conclude this paper is as follows. Adjusted efficiency values using three-stageDEA has significant differences compared to the former value, it indicates that it isvery important. Divided the three regions we can see that the efficiency of three re-gions are east>middle>west. In2007-2011,the movement trend of total factor elec-tric energy efficiency is increased first and then declined. Change in techno logyprogress is the main driver of change in the progress of electrical energy consump-tion effic iency. From2007to2011, electric energy consumption efficiency in na-tionwide does not exist convergence, efficiency gap in region is more and more ob-vious。Convergence indicates that eastern region has a higher energy consumptionefficiency and a smaller difference,but the internal of center region and west regionboth have large differences, electrical energy consumption effic iency needs to beimproved soon.Policy proposals based on the analys is and study are as follows. From a na-tional perspective, adjusting the energy structure as soon as possible, encouraging the introduction of advanced science and technology are necessary; From a regionalperspective, we should strengthen cooperation and communication between pro v-inces; From the industry perspective, adjusting the industrial structure according todifferent situations of each province and limiting the development of high e n-ergy-consuming industries; From the level of termina l electric consumption, im-proving the awareness of energy conservation, innovating technology and manage-ment are the emphasis of improving electric consumption effic iency.
