| 摘 要： | 以滞量τ为分支参数,研究了具时滞的能源价格模型的动力学行为,这些行为包括：系统在平衡点附近的稳定性，局部Hopf分支的存在性，发生条件Hopf分支的方向，分支周期解的稳定性以及分支随参数变化其周期解的周期变化.最后通过数值模拟验证了理论分析结果，并用分支理论解释了能源价格模型产生且维持周期振荡的原因.

| Abstract: | This paper studied the dynamic behaviors of energy Price Model with the time delay as bifurcation parameter. These dynamic behaviors include the stability near the equilibrium, the existence of the local Hopf bifurcation, the direction of the Hopf bifurcation, the stability of the periodic solution, and so no. At last, some simulations were carried out to support our theory findings, and some explanations were given about why the energy Price Model would generate periodic oscillations. |
