| At present, China’s economy is facing many problems, which became China’s energy shortage and environmental pollution problems caused worldwide attention. However, to solve these two problems, it is necessary to improve energy efficiency. To improve energy efficiency, we must first figure out what is energy efficiency, followed by analysis of the status quo of China’s energy efficiency, the last to be developed based on research to improve energy efficiency path, countermeasures.Is to improve China’s energy efficiency for the purpose and the main line, through empirical analysis, the use of productivity theory, such as knowledge of environmental economic theory, the use of existing research methods, economics, energy efficiency calculations made on the physics energy efficiency in China. Economics estimates the status quo of China’s provinces and autonomous regions in energy efficiency with a single-element method and total factor method analysis. In total factor analysis, the use of DEA model to calculate the evaluation unit (all provinces in the eastern region, central region, northeast old industrial base, the western region and the country) energy efficiency. And pointed out the inadequacies of the existing research methods.The first chapter of this paper, first from China’s energy supply, demand, the use of four levels of environmental pollution, energy issues, exposing depicts China is now facing huge difficulties and challenges of achieving sustainable development in China, which leads to research energy efficiency the importance and necessity. Identify the single factor analysis of the pros and cons of energy efficiency, and to identify the energy efficiency of total factor method used input indicators, output indicators, and they were analyzed by analysis of energy efficiency research status. Of this research ideas, methods and innovation.Chapter Ⅱ summarized the theoretical basis of this article as a whole Institute. The purpose of this paper is to build a set of objective, a comprehensive evaluation index system of China’s energy utilization efficiency, and build the index system is the first thing to do is measure of the indicators, the existing research results, energy efficiency evaluation measure single factor, total factor two, this will use these two methods to analyze China’s energy efficiency, and analyze the results of these three different evaluation methods in Chapter contrast energy utilization efficiency. The next step is to measure good indicator in accordance with the purpose of the research needed to achieve integration. This article will measure indicators of integration for energy conservation, efficient use of energy and pollution reduction three subsystems, and apply the results of these three subsystems theory that the efficiency of energy utilization.Chapter use of existing energy efficiency assessment methodology reviewed the status quo of China’s energy efficiency. First defined the energy efficiency of physics, economics, the definition and measurement of the the Physical energy efficiency in China Based on this analysis, to do a more detailed analysis of energy efficiency changes in trends and international. Found that China’s exchange rate, energy consumption per unit of GDP gap with the international advanced level is significant, while the energy consumption per unit of GDP at purchasing power parity differences with the international advanced level is significantly reduced, thus that do international comparison of energy efficiency, purchasing power parity terms of energy consumption per unit of GDP more accurately reflect the real level of energy efficiency in China. Next, the chapter draws on data envelopment analysis (DEA) in the BCC model design total factor energy efficiency calculation method, in terms of investment in energy consumption, crop acreage (characterization of biomass energy inputs), capital stock, human the capital four variables, including human capital takes into account the quality of workers factors, DEA model input-output variables should not be too much using entropy method "industrial waste" Merge into one variable-Environmental Pollution Index (API), and take the reciprocal of DEA model of non-consensual output, so that output a total of the countdown two variables of GDP and environmental pollution index. The results from a regional perspective,1995-200713years on average, of the four economic regions in total factor energy efficiency descending order:the eastern coastal areas of the northeast old industrial base, the central region,and the western region. At last, the results of the analysis for the first three quarters of this chapter, pointed out the inadequacies of the existing energy efficiency evaluation method that influencing factors in the analysis of energy efficiency, has not yet formed a unified standard system, which makes the conclusions of different scholars can not form consensus can not provide a standard for the actual policy-making.Chapter Ⅳ according to the meaning of the efficiency of energy utilization index system and its construction purposes, designed to reflect a more comprehensive energy conservation, efficient use of energy, the pollution reduction indications energy efficiency evaluation index system. Four levels of evaluation, three evaluation system,27variable factors. Subsystem energy savings, energy-efficient use of the meaning and role of the subsystem and pollution reduction subsystem evaluation done a detailed explanation. Finally, the method of calculating the energy utilization efficiency evaluation model and its index weight selection methods have been defined.Chapter first energy utilization efficiency evaluation model, variables and data interpretation. Use of factor analysis, factor analysis model building energy utilization efficiency, sources do work out detailed energy utilization efficiency of the evaluation process based on factor analysis, data acquisition, and data preprocessing. In accordance with the energy utilization efficiency of processes based on factor analysis, respectively, of China’s29provinces, autonomous regions and energy savings, efficient use of energy, the three sub-systems of the pollution reduction is calculated according to the corresponding right to re-measure the energy complex of the29provinces, autonomous regions, according to the calculation results use efficiency performance index for three major subsystems and energy utilization efficiency value of29provinces rank and partition, it can be seen, the eastern provinces of comprehensive energy efficiency performance ranked in the front position, the central The northeast provinces positioned in the middle western provinces by comparison.Chapter Chapter on the calculation results of the energy utilization efficiency of China’s30provinces, autonomous regions, and choose the path of energy conservation, efficient use of energy and pollution reduction three subsystems proposed to increase the efficiency of energy utilization in China. That a higher energy savings performance index, improve the system of energy saving laws and regulations, the development of industry and the highest standards of energy consumption and logo; second is the establishment of national energy management agencies, unified management and coordination of energy policy implementation process is necessary to create a; priority to the development of high-tech industries, upgrade the industrial structure and high-class; control the excessive growth of high energy consumption industries, accelerate the elimination of backward production capacity; intensify promoting energy conservation, promotion of energy-saving products, to achieve universal energy-saving; emphasis on energy-saving policy of regional differences in a timely manner modify, adapt policies to enhance energy-saving policies, energy efficiency standards; develop incentives and fiscal policies, and strengthen long-term regulatory mechanism based on market-based instruments and economic laws; development of distributed energy, promote energy cascade utilization of technology. Improve the efficient use of energy performance index path:efforts to improve the efficiency of the energy scale; and vigorously improve energy efficiency of the allocation; actively adjust the industrial structure, vigorously develop the tertiary industry, efforts to reduce the proportion of heavy industry; increase investment in technological progress, improving the industry sector the level of energy use; improve the level of China’s opening up, China’s enterprises to improve the level of energy use through cooperation with the world’s most advanced enterprise; improve the market economic system, to promote the energy efficiency of the nation as a whole through the orderly flow of energy resources; vigorously develop the circular economy development of renewable energy.To further improve energy efficiency, promote energy conservation, and the establishment of saving and environment-friendly society, need to correct evaluation of the energy efficiency of the provinces, autonomous regions and municipalities directly under the Central Government, and combined with its energy conservation, energy efficiency and pollution reduction, find the root causes of the path to improve energy efficiency. |
