In order to research the relationship between the economic development and the carbon emissions since Chongqing municipality directly under the Central Government.Take 1997--2008 to research the correlation of economic development and carbon emissions in Chongqing . In this period carbon emissions has increased 2.43 times and growth change process is divided into two categories:volatility drop stage during (1997-2000) and (2005-2008);steady rise stage during (2000-2005). To analyze the carbon emissions change and economic output, the energy structure, industrial structure, and efficent use of energy resourcesk, the results show that : carbon emissions will generally increase with economy, among them the local consumption on the contribution of carbon emissions is the highest and dominant , average contribution rate is 79%. In the second industry, the emission of work is reflected in energy consumption, the reduction in energy consumption has important role in the decrease of carbon emissions. In the future, industrial structure adjustment should focus on the second and third industry and construction, improve the industry on energy efficiency. The main way to reduce the emissions of the future is to optimize the energy structure, raise the proportion of clean energn;to optimize the industrial structure and reduce the energy consumption;to improve energy consumption structure and raise the use efficience; to increase vegetation cover, and improve soil carbon sequestration ability; to advocate low carbon life and build low carbon society;to improve policy and regulations system and strengthen management.
