Energy Efficiency Measures And The Energy Saving Potential Analyses In Liaoning Province

Energy the most basic driving force as the human society development and economic growth,has always been the hot topic in academic circles.Energy efficiency can both satisfy the economic and social development and can reduce the pressure of environmental pollution,so as to increase economic efficiency,enhance the overall competitiveness,therefore,to improve the energy efficiency is an effective way to countries all over the world to achieve sustainable development and the important premise.In this paper,based on this background,first of all on the research literature of energy efficiency and energy saving potential,analyzes the related areas the latest theory research progress at home and abroad,and measurement model of energy efficiency and measurement model of energy saving potential was reviewed.This paper applies the SFA model evaluating energy efficiency of each city in Liaoning province,from the whole aspect,Lorenz curve is applied to analyze the unbalance of energy efficiency;from the local aspect,Gini coefficient,Theil index,and Tsui-Wang index are applied to research polarization characteristics in Liaoning province,using Tobit regression model explore its influence of energy efficiency on PCG?SIGP?OPEN and EPI,from the time and space dimensions,Using kernel density estimation and hierarchical clustering method to demonstrated energy efficiency in Liaoning province,finally through the time series data,construct the energy and environment learning curve model,and on this basis,to measure the energy saving type and energy saving potential of the cities in liaoning province.The result shows that: Energy to economic growth of Liaoning province(2000-2014)regression coefficient is 0.129,comparing with energy to economic growth of the central six energy provinces regression coefficient 0.046,higher than0.083.Energy efficiency exists obvious differences between different cities in Liaoning province,by linking the decreasing trend along the axial of Shenyang and Dalian to both sides;besides the provincial energy efficiency distribution pattern is relatively stable.On the whole,the energy consumption of Liaoning province has been greatly improved,and the energy space distribution is more balanced.From the local level,the energy efficiency difference between cities is continuously reduced,and the spatial differentiation is not obvious in Liaoning province.Energy efficiency of the cities can be divided into three categories.PCG?OPEN and EPI are important influence factors of energy efficiency,and have a positive effect;SIGP's influence on energy efficiency is not a linear drab,but there is a “turning point”.The cities of higher level of economic development,the amount of outputenergy consumption load is smaller,and the energy-saving potential is lower;on the contrary,the cities of lower level of economic development,the amount of output energy consumption load is greater,and the energy-saving potential is higher.The focus of energy conservation should be put in Fushun,Fuxin,Tieling,Chaoyang and Huludao five cities.The energy saving potential of 2014 I,II and III is 0.0580 tce,0.0125-0.0221 tce,0.0016-0.0082 tce.Finally,based on the above analysis conclusion,the paper puts forward the implementation of the strategy of building a resource-conserving and environment-friendly society in the relevant policy recommendations,to improve energy efficiency and energy saving potential problems that need to pay attention to in the process of mining and solution.
