随着电力市场的建立，销售电价的市场化改革成必然趋势，本文借鉴Stackelberg微分博弈方法，并基于政府规制的思想，建立政府与电网企业间两阶段微分博弈模型，运用逆向归纳法与Hamilton-Jacobi—Bellman方法求解，得出政府和电网企业的最优策略；模型的数值仿真表明：随着电力行业市场化改革的推进，销售电价、电网企业的供电量与政府的转移支付量均收敛于某特定值。

英文摘要：

With the establishment of the electricity market, the market-oriented reform of electricity price becomes an inevitable trend. In view of Stackelberg differential game and based on the idea of Government regulation, a two-stage game model between Government and Power Enterprise was established in this paper. By using backwards induction and Hamilton-Jacobi-Bellman approach, the optimal strategies of government and the power grid enterprises are obtained. The numerical simulation of the model shows：with the development of market-oriented reform,electricity price,the power supply of Power Enterprise and the transfer payments of the government are convergent in a certain value.
