This article establishes a useful analytical framework
for complete carbon emission of the industries in China and then
makes comparison on carbon emission among these industries based
on the latest data derived from China's Input-Output Table and
Energy Statistics in 2007. It is found that some industries are
``invisible high-carbon" sectors by the definitions of
directly-embodied coefficient and perfectly-embodied coefficient
and that others have made contributions to carbon leakage by
measure of importing and exporting carbon emission volume.
Finally, this article provides suggestions to industrial
strategies, trade policies and the comprehensive economic
management policy in order
to effectively achieve energy conservation and emission reduction.
