Vigorously promote energy conservation, is the inevitable requirement of our country to take a new road to industrialization, but also the smooth realization of the goal of building a moderately prosperous society imperative. Energy conservation is the need to achieve sustainable development based on China's national conditions, but also an important measure to safeguard energy security and protection of the environment. China in industrial energy use, the adjustment of industrial structure, policies to promote universal energy efficiency, energy savings potential. Taken to improve the level of energy development and utilization, and adjust the industrial structure, the development of effective energy-saving policy, strengthen the construction of energy-efficient legal system, and to advocate establish consumer awareness of conservation measures, effectively promote the implementation of energy conservation. From the macro level, the paper first introduces the theory of energy efficiency and structural changes, followed by the establishment of the model to calculate the 1990-2007 the social total energy savings, as well as coal, oil, natural gas, electricity savings, using multiple regression analysis its influencing factors. Analysis of the total social energy saving, consider the three influencing factors: the structure of energy-saving, technology, energy-saving and life energy-saving, and factor analysis of the energy of the 1990-2007 social summarize, as a basis for the establishment of the summed energy factors The evaluation model. The results showed that the technical energy efficiency is the main driving force to promote energy conservation in China in recent years; structural energy-saving and negatively correlated with the total energy savings, currently there are irrational industrial structure in China, China Energy Conservation should focus on strengthening the adjustment of industrial structure. Analysis showed that the impact factors of the coal, oil, natural gas, electricity savings for coal and electricity, the technology is the most important factor of its energy structure its not significant; for oil and natural gas, the structure and technology of its energy savings are positive related and technical energy efficiency is the most important factor affecting its energy savings. Therefore, the first to raise the technical level of the technology, especially the secondary industry to save energy. Energy, focusing on the grassroots level, focusing on business. Energy efficiency at the enterprise level, an effective means of labeled as the industrial sector energy efficiency is an important foundation for energy saving. Elaborate on the basis of energy efficiency standard implementation steps, the energy efficiency index analysis on key energy consuming sectors - steel, cement, chemical, and pointed out that the energy efficiency standard application. Finally, according to the the macro enterprise level analysis to make policy recommendations for China's energy-saving management. Adjust and optimize the industrial structure, vigorously develop the tertiary industry, and improve a variety of energy-saving systems, energy efficiency benchmarking in the heavy industry sector.
