Abstract: Aiming at the coordination relationship between carbon emission and economic growth, the annual data of 10 major carbon emitting countries (China, United States, India, Russian Federation, Japan, Germany, Korea, Saudi Arabia, Canada and United Kingdom) have been chosen to conduct an empirical study. The main research results include: The results of coordination analysis on carbon emissions and economic growth in different countries vary a lot. The EU countries share better coordination in low-carbon economy with lower carbon emission per capita and higher GDP per capita. However, some developing countries such as China and India need to be enhanced. EKC hypothesis and decoupling theory are unified measurement of low-carbon(when studying the carbon intensity by these two methods, the consistent elasticity and similar results can be obtained), and the EKC regression coefficients β and Tapio decoupling elasticity e can be taken advantage of respectively to build low-carbon indicators of long-term and short-term goals. In the respect of promoting low-carbon economy development, developing countries should learn from EU countries in the pursuit of coordination between lower carbon emissions and higher economic growth.
