With GDP and TEC (Total Energy Consumption)data from 1953 to 2005,this paper establishes a nonlinear dy- namical system (GDP-TECNLDS) between GDP and TEC.It shows that there exists an accelerating relationship be- tween GDP and TEC mutually,and the Coupling mechanism between GDP and TEC puts a curb on the TEC growing. Therefore,we must adopt the measurement to change the movement track of GDP-TECNLDS,and if we adopt optimum control,then we will realize the target of TEC/GDP to descend 20% in the 1 l th programming well.Therefore,we must maintain quick but not excessive GDP growth.
