我国能源效率与经济增长关系的实证研究

An Empirical Study on Energy Efficiency and Economic Growth in China

众所周知,提高能源效率对促进我国经济增长具有重要意义。在结合国内外关于能源效率与经济增长问题的研究基础上,采用1978—2011年间的我国能源效率与经济增长的相关数据,运用协整分析与Granger因果关系检验方法来分析能源效率与经济增长之间的动态关系。实证研究发现:我国能源效率与经济增长之间存在着长期的均衡关系。而Granger因果关系检验表明:在1978—2011年间,我国能源效率与经济增长之间互为因果关系,即能源效率提高能够促进我国经济增长,同时经济增长也能带动我国能源效率提高,能源效率与经济增长两者之间是一种互相促进的关系。

As we all know,the increasing energy efficiency in China is important for economic growth. On the basis of domestic and abroad research about energy efficiency and economic growth, the paper utilize the methods of the E-G two steps methods, the co-integration analysis and Granger causality estimation state space model to test the relationship between energy efficiency and economic growth based on the data in the period of 1978--2011 in China. The results show that there is close causal connection between the energy efficiency and economic growth from 1978 to 2011. And the double-direction causality between energy efficiency and economic growth is found. Namely energy efficiency can promote China＇ s economic growth,while economic growth can bring China＇ s energy efficiency. There is a mutually reinforcing relationship between both energy efficiency and economic growth.
