本文运用经济学原理及古诺博弈模型对电力市场的排污收费制度进行研究,分析排污收费前后电力市场均衡的变化,推导出了古诺博弈均衡的通用解,分析了企业排污系数(βi)、企业边际生产成本(bi)和政府施行的排污收费税率(r)对均衡结果的影响,分析了征收排污费过程中发电企业的行为选择过程,认为电力企业从自身利益出发,会根据排污收费税率(r)来调整其排污量。最后提出了政府如何制定排污税率的建议。
The paper researches the system of effluent charge in power market with the economics theory and Cournot game model. Analysis the change of balanced result after effluent charge and finds out the currency results. Paper also analysis how the coefficients (βi, bi and r )influence the currency results. At last paper gives some advice to the government on how to establish the coefficient.
