Since the21st century, climate problem has become one of the major challenges facing humanity, how to achieve carbon reduction, as well as the hot topic of common concern. Intergovernmental panel on climate change (IPCC) specifies the main developed countries between2008and2012of the emission reduction task, but the provision of the responsibility to reduce emissions in developing countries such as China. As the first big emitters, China promised to achieve in2020per unit of GDP carbon emissions (carbon dioxide emissions intensity) on the basis of2005fell by40%-45%of the target, achieve this goal, must pay a very large economic cost, and carbon dioxide in fully understand the provinces domain, on the basis of efforts to improve the efficiency of carbon dioxide emissions, is the best path to achieve emission reduction efficiency.This article is divided into five parts. First of all, through the literature research summary of relevant research methods and conclusions; The second part, comparing China’s overall carbon dioxide emissions to other countrys’ and calculating the provinces’ carbon dioxide emissions, And on this basis to choose the appropriate decomposition method to analyze their variation characteristics; The third part, expounding the theoretical definition of efficiency of carbon dioxide emissions, and the research methods of later for detailed instructions, providing theoretical basis for later study; The fourth part, using stochastic frontier function method, calculates the provinces domain efficiency of1995-2010carbon dioxide emissions, analyzing carbon dioxide emissions efficiency characteristics and comparing difference based on the results of the calculation,and using kernel density estimation method to convergence of the differences between the provinces domain emission efficiency test,select suitable efficiency influence factors index, analyzed the influence factors of co2emission efficiency; The fifth part; Policy and advice.Main conclusions are:(1) the efficiency of China’s overall carbon dioxide emissions on the rise, but the efficiency value is low, average efficiency value during the entire study sample was only0.703, there are emission efficiency differences between the domain provinces, the eastern region emission efficiency is significantly higher than the central and western region, the central region close to the national average level, higher than in the west of the provinces;(2) government intervention, R&D input and efficiency of carbon dioxide emissions are related, and openness, urbanization, coal consumption proportion in total energy consumption, the second industry output value proportion in GDP are negatively related to the efficiency of carbon emissions;(3) The emission efficiency of the provinces domain difference slightly narrowing trend after2002.
