煤电运营商最重要的一类生产决策，是如何将运营成本在燃料成本支出、节能创新投入和环保创新投入之间做出相对合理的配置，在达到污染排放标准的同时实现企业利润最大化。基于寡头垄断市场结构的煤电厂商两期动态博弈，存在三类典型竞争策略下的最优创新水平和最优产量水平的市场均衡。均衡创新水平和均衡产量均随着节能环保创新比例的增大而增大，而节能创新技术溢出对均衡产量有正向影响，对均衡创新水平的影响随着市场结构的不同而变化。基于三类不同社会福利函数设定的福利经济学分析，如果考虑环保创新及其技术溢出效应，则更深程度和更广范围的各类电力市场竞争能带来更大的社会福利。

China has become the country with the largest total energy consumption nowadays, and is also one of the largest county of coal reserves, coal-fired power generation capacity and electricity production in the world. Chinese regional electric power market structure, which seems to be oligopolistic competitive one, shows an important characteristic in the process of the market-oriented reform of Chinese electric power system. For thermal power firms such as coal-fired plants（CFP）, one of the most important production decisions to make is how to allocate the operating costs among fuel costs, innovation expenditures for energy saving and those for environmental protection in order to achieve firms＇ maximum profits and reduce pollutant emissions as well. The purpose of this paper is to study the market equilibrium, its influence factors and welfare implications of those decisions, and to show the policy implications which may throw light on the rnarket-oriented reform of Chinese electric power system at present.
