Abstract: In the background of developing low carbon economy all around the global,our country has also made a national call to save energy and reduce emission , optimize the industry structure, and take a new-style industrialized way, therefore, the scientific judgment of decoupling relationship between the industry economy growth and carbon dioxide has important theoretical value and practical significance.Tapio Decoupling Index is used in this paper to build a theory model on analyse decoupling relationship between sector development and carbon dioxide,then do positivist research on 28 manufacture sectors by using the data between the years 1999-2003 and 2003-2008.The conclusion is that,in the last decade ,the decoupling relationship between carbon emissions and economic growth is in the state of weak decoupling for most of the manufacture sectors,and the decoupling level has been enhanced,the energy saving elastic index shows that these results mainly because of the improvement of the energy using efficiency in our country,however,the task of reducing the carbon emission is also very difficult,it requires the enterprises, our government and the society to make a joint effort.
