Abstract: This paper derived the SDA model in terms of coefficient of carbon emissions, and established the LMDI equations to analyze the impact factors for carbon changes in total. As an example, Yunnan Province is analyzed based on energy consumption data and four years input-output table. The results of SDA model shows that expansion effect of consumption and investment is a source of carbon emissions, and the changing effect of carbon intensity is the main measure to save energy and reduce emission. The results of LMDI show that the PGDP growth is the decisive factor in stimulating growth of CO2 emissions, and the decline of energy intensity is the most important factor to inhibit carbon emissions growth in Yunnan Province. In the last part, this paper provides the suggestions for the structure adjustment with low carbon economy system in Yunnan Province.
