Abstract: Energy efficiency in China has a great gap with developed countries. Even among different regions in China, energy efficiency has huge differences. This paper investigates the impact of administrative monopoly power price on regional energy efficiency. Based on the analysis of its conduct mechanism, the empirical section data of various provinces in China in 2006 are used to check the hypothesis of this paper. The finding is that the huge difference in administrative monopoly power price among regions is an important factor impacting energy efficiency, the higher the administrative monopoly power price, the higher the energy efficiency .The artificial inter-provincial barrier in power market and administrative monopoly power price hinders the circulation of power resources among different regions so that there is no efficient allocation of resources all over the country. Besides, it is hard to rectify low allocation efficiency by relying on market force. Regional protectionism and inter-provincial barriers of the power market should be broken to form uniform national power market so that energy efficiency can be enhanced and huge energy saving potentials can be released © 2011 Published by Elsevier Ltd.

Abstract: Under the frame of Total-Factor Energy Efficiency, considering desirable outputs and undesirable outputs taking by energy and related factors, this paper uses super efficiency DEA method to measure energy efficiency of 11 provinces (autonomous regions, municipalities) in western China from 1989 to 2009, and utilizes fixed effect model of variable intercept to analysis factors of influencing energy efficiency of provinces (autonomous regions, municipalities) in western China. The analysis shows that: (1) Under the situation of overall low energy efficiency in western China, in region, energy efficiency level presents the slow rise tendency from the year of 2005 after maintaining certain time interval slow drop. In the region the difference is small. (2) Factors of technical progress, industrial structure, government influence, opening degree, system variable as well as structure of energy consumption have different effects on energy efficiency, and these factors to action mechanism of energy efficiency exist difference.

Abstract: This article evaluated the energy effeciency in Hebei Province using some indicators such as comprehensive energy consumption, efficiency of energy transformation. Then it makes a comparative analysis about the HeBei Province''s status in the country''s energy conservation. The final part of the paper predicts energy consumption indicators in HeBei province from 2009 to 2013. [Copyright &y& Elsevier]
