Abstract: Based on the product quality improvement theory, this article constructed an economic growth model which taken the energy efficiency improvements and carbon dioxide emission reduction into account, then used the panel data of 35 sub-industrial sectors in China from 1999-2011, this paper discussed the double-edged effect of technological progress which through the energy efficiency improvements and economic growth to lower the carbon dioxide emissions in industry. Results indicate that the technological progress through the energy efficiency improvements is still unable to eliminate the industrial carbon dioxide emissions brought by the economic growth; however, it can lower the carbon dioxide emissions intensity of light industry and heavy industry. Compared with light industry, the energy efficiency improvements of heavy industry have stronger impact on carbon dioxide emissions than economic growth. By boosting the heavy industry's green technology innovation to improve the energy efficiency should be the entry point and the focus of energy saving and carbon dioxide emission reduction in the future.
