Abstract:In this paper, which is based on 1995-2012 statistical data, usd the IPCC (2006) calculation method to estimate the total amount of carbon emissions in Jiangxi energy, and builded carbon emissions energy and economic growth decoupling index model, empirical analysis of the decoupling relationship between carbon emissions and economy growth. in Jiangxi. The results showed that decoupling relationship between carbon emissions and economic growth in Jiangxi was instability ,decoupled state, strong decoupling, weak decoupling existed alternately,On this basis,the paper further analysis of the reasons for the decouple state changes of the carbon emissions and Jiangxi economic growth, and make recommendations to Jiangxi in order to develop low-carbon economy.
