Abstract: Based on the complete decomposition model, the main influencing factors on the energy consumption/saving in Liaoning Province are studied, such as energy intensity and industrial structure. The results showed that although the energy intensity plays an important role in energy saving, the industrial structure relates closer to energy saving. How the industrial restructuring steps up energy saving is therefore discussed statistically by regression analysis. It was found that there are significant relationships between the output value percentages of the industries, including industry, construction and transportation, and energy saving, and the critical proportion of output values of the three industries available to step up energy saving in Liaoning Province is given by analyzing the regression results. It was revealed that the changing trend of output value percentages of manufacture and transportation industries stepped up the energy saving.
