Abstract: Based on the sample of 1979-2010 years, vector auto regression model of energy consumption, technological progress and economic growth is established. The dynamic relationships between them are empirically analyzed using the econometric method of the cointegration test, Granger causality test, impulse response function and variance decomposition. Conclusions are obtained as follows: In the long term, there is a negative correlation between energy consumption and economic growth in China, and technological progress has a significant positive effect on economic growth. In the short term, technological progress, economic growth is the Granger causality of energy consumption. Impulse response of economic growth to energy intensity is firstly positive, and then negative. The impact of technological progress on economic growth is positive, which has an inhibitory effect on energy consumption.
