摘要
This paper discusses the factors influencing Chinese energy intensity from 1980 to 2003 based on adaptive weighting Divisia index method and the analyzing results are different in different phase. In period of 1980～1990, both the structure factor and the technology factor effected positively Chinese energy intensity＇s fall but the former became inefficacy and even turned out to be negative in 1991～2001 meanwhile the later factor strengthened its function. After 2001, the two factors promoted Chinese energy intensity＇s rising together. The conclusion is given in the end.
