Shaanxi Province Total Factor Calculation And Influencing Factors Of Energy Efficiency Analysis

Shaanxi Province has a huge energy possession, especially posses an abundant of coal resource. In recent years, the process of industrialization of Shaanxi Province is speed up, the energy consumption increased significantly; it makes the economic of Shaanxi Province developed rapidly. However, the development is based on the great energy consumption; the economic growth is an extensive growth which is not beneficial for the sustainable development. In another side, coal consumption is priority to energy consumption structure in Shaanxi Province, coal consumption will make influence on environment. Therefore, to improve energy efficiency of Shaanxi Province is necessary and urgent. At the same time, the problems of environmental pollution in the process of energy utilization must be considered.This paper uses the combining mode of theoretical analysis and empirical research. In the theoretical analysis, we study and analyze the literatures on estimation of total factor energy efficiency and influence factors, and we also analyze the relationship among economy, energy and environment through the description of status of economy, energy and environment. In the empirical research, the paper is based on the panel data of Shaanxi Province from2001to2010, and uses the Malmquist Index separately calculate and decompose the energy’s economic efficiency and energy’s environmental efficiency of Shaanxi Province. And use the econometric methods to analyze the affecting factors of total factor energy efficiency.In this article, the main conclusions are as follows:the energy’s economic efficiency and energy’s environment efficiency of Shaanxi showed a trend of declining, but the energy efficiency index has increased year by year, it means the decline of energy efficiency is reducing; it has a great space to improve the energy efficiency. We compared the change of energy’s economic efficiency index and energy’s environment efficiency index, and found that before2006, the energy’s environment efficiency index of Shaanxi is lower than the economic efficiency index; it means the environmental pollution make great effect on energy’s environment efficiency. After2006, the energy’s environment efficiency became approaching to economic efficiency, it indicated that there become a balance between energy economy and energy environment. By the decomposition of total factor energy efficiency we found that the technological progress is the key effective factor to the energy efficiency. And the growth of technological efficiency is benefit from the growth of efficiency of scale, there are few regional differences. Further results of regression analysis of affecting factors show that energy consumption structure and market opening can describe73.6%of changes on energy efficiency, they are the most important factors that affect the energy efficiency’s changes.
