Abstract: As the world's most populous country, and because of the rapid economic development, China will inevitably increase the carbon dioxide emissions. According to statistics of 2007, China's carbon dioxide emissions are 6071.77 million tons which was over the United States and China became the world's largest emitter of carbon dioxide. China has formally proposed to be bound targets to reduce carbon dioxide emissions intensity, China's carbon dioxide emission intensity is 40% to 50% in 2005 to 2020. In order to study how to achieve this constraint in 2020, this paper analyzes the various factors to affect China's carbon dioxide emissions. Energy efficiency is the efficiency of the inhibition of carbon dioxide emissions factors. In recent years, China's energy use efficiency is steadily improving, but relative to developed countries, China's energy efficiency is still very low, there is room for growth. The efficiency of energy use can inhibit China's carbon dioxide emissions. Therefore, the efficiency of energy use can help study how to reduce carbon dioxide emissions. This paper first introduces the background of China's carbon emission constraints, this chapter elaborated the impact of carbon dioxide on the environment, into Seoul threatens human survival, as well as China's policies to deal with. Followed in the first chapter of the status quo of China's carbon dioxide emissions and the logarithmic mean Divisia decomposition method to analyze the impact of China's carbon dioxide emissions factors, and draw the conclusions that energy efficiency is an important factor in the suppression of China's carbon dioxide emissions. The second chapter estimates China's total factor productivity and use DEAP2.1 software, and total factor productivity in China to make the evaluation. Chapter III analyzes the binding targets of carbon emissions, energy intensity values measured in 2020 which China needs to achieve, and to analyze the factors that affect our energy efficiency. Finally, according to this analysis, we should adjust the industrial structure in the carbon emission constraints.
