摘　　要：研究钢铁行业余热余压发电与传统火力发电组成的电力市场,分析钢铁企业余热余压发电上网电价策略.建立了有关钢铁企业、传统化石燃料发电企业和地方政府三方的斯坦克尔伯格博弈(Stackelberg)模型,比较余热余压发电技术上网电价的三种定价策略(固定价格、固定溢价和可变溢价),并进行了数值模拟分析市场规模、余热余压发电成本系数和钢铁企业环境成本对最优规制价格、最优钢铁企业利润和最优社会总福利的影响.结果表明:三种定价策略下最优规制价格、最优钢铁企业利润和最优社会总福利差异非常大.不同偏好的政策制定者会从不同的风险性和补贴选择不同的定价策略.其中,风险性大和补贴高是最优规则价格中的可变溢价策略、最优钢铁企业利润中的固定溢价策略和最优社会总福利中的可变溢价策略;风险性低和补贴低是最优规则价格中的固定价格策略、最优钢铁企业利润中的固定价格策略和最优社会总福利中的固定溢价策略;其他情形的风险性和补贴位于这两种情况之间.This study analyzes the feed-in tariff strategy of steel enterprises in the context of the steel industry’s electricity market,which is composed of waste heat and pressure(WHP)power generation and traditional thermal power generation.A Stackelberg game model was developed to compare three pricing strategies(i.e.,fixed price,fixed premium,and variable premium)for the feed-in tariff of WHP power generation technology among steel enterprises,traditional fossil fuel power generators,and local governments.Three pricing strategies for WHP generation feed-in tariffs are compared,and numerical simulations are run to examine the effects of market size,WHP generation cost coefficients,and steel firm environmental costs on optimal regulated prices,optimal steel firm profits,and optimal total social welfare,respectively.The following findings are obtained.(1)For optimal price regulation,increasing the market size and the coefficient of WHP generation cost has little effect on the optimal price regulation under the fixed price policy.The only way to increase the price of the fixed price policy is to increase the environmental cost of steel enterprises.Moreover,increasing the market size and the coefficient of WHP generation cost will reduce the price of fixed premia.Additionally,increasing the market size and the coefficient of WHP generation cost will reduce the price of fixed premia.Increases in market size and WHP generation costs will raise the price of variable premium insurance,whereas increases in enterprise environmental costs will lower and maintain the price of variable premium policy.(2)For optimal steel enterprise profit,increasing the market size and the cost coefficient of WHP generation will increase the profit of steel enterprises under the fixed premium policy.However,it will have little effect on the profit of the fixed price and variable premium policies.Moreover,increasing the environmental cost of enterprises will reduce the profit of the fixed premium policy,but it will have little effect on the profit
