The energy is the important material foundation of a country's economic growth, and social development, economic development and energy use are closely related. EMD method is used for the first time to comparatively analyze the correlation of the increase of energy consumption and that of GDP in China. This paper tries to find out the correlation of the fluctuations between them in new ways. It reveals the relationship between energy consumption and GDP. Consequently, this will provide us some reference to the long -term socio -economic planning, energy development strategy and the formulation of relevant policies and regulations. The result shows that the increase of GDP reveals the time-scale fluctuations of about 4 years, 11 years, 18 years and 31 years. The increase of energy consumption reveals the time -scale fluctuations of about 4 years, 10 years, 18 years and 27 years, and the cycles of them match basically. We make a comparative analysis of their IMFs, and discover that energy consumption and GDP are interdependent. The conclusion shows that the theory of economics, energy consumption can advance economic growth, and energy development should take economic growth as the prerequisite. The shortage of energy will constraint on economic development. Therefore, using every means to increase energy supply and improve efficiency of energy use would be a major task to ensure China's sustainable and stable economic development.
Key words： EMD; IMF; the increase of energy consumption; the increase of GDP
