摘要：The relationship between economic growth and CO2 emission is an important indicator in the construction of low-carbon economy.Yangtze River economic belt (YREB)is one of China's″three supporting belts″.Thus,it is of great importance to study the relationship between economic growth and CO2 emission in YREB. Tapio decoupling model and improved WCDM (weighting complete decomposition model)are applied to study the decoupling relationship between economic growth and CO2 emission and its driving factors in 1995-2013 in YREB.The results show that:the three industrial CO2 emission amount in YREB roughly increases year by year in 1995-2012 and decreases slightly in 2013 while taking one third of the total CO2 emission amount of the whole country.The second industry is main resource of CO2 emission accounting for about 80％ of total amount.The relationship between economic growth and CO2 emission shows weak decoupling state in most years of the study period,strong decoupling state and expansive negative decoupling state exist in the other years.The economic factor is the main factor leading to the negative decoupling state and the energy intensity factor is the most crucial factor facilitating the decoupling process.The economic structural factor prevents the economic growth decoupling from CO2 emission and the effect of CO2 emission factor is unstable.
