Based on such statistical data from 1997-2007 as GDP, total energy consumption, industrial structure of energy consumption and energy consumption types, drawing on gray relevance, this thesis establishes three models to computationally analyze the correlation between energy consumption and economic development, and on this basis puts forward ways to imply energy conservation measure, increase energy utilization efficiency; develop agriculture and service industry, reduce the dependence on energy; develop the clean new energy, promote structure of energy consumption multiplication and so on 
