Abstract: The energy consumption change in eastern part of China was calculated based on Laspeyres index complete decomposition method, and accompanied with comparison between its vertical and horizontal aspects. The results indicate that economic growth is a main factor that pushes ahead with the increase of regional energy consumption, and technological progress and structural adjustment play an important role in energy conservation. Meanwhile, improvement of the sector energy efficiency is the predominant cause of energy conservation. Only very small changes in industry sector structure and energy efficiency could have great impacts on the whole energy conservation, among them, increasing energy efficiency is crucial to the technological conservation. It could also learn from results that short-time conservation effects of structure adjustment characterized by phase variation are not so obvious; the root is in the investment effects of high-resource dependent industries, earlier stage overdraft of energy consumption, ant its lag effects, which led to weaken the structural effects. Finally, some suggestions involving industrial structure adjustment, energy structure optimization, and energy efficiency elevation, etc are given.

Key words: structural change, energy efficiency, economic growth, energy conservation, factor decomposition
