摘　　要：煤炭是中国最重要的能源,而电煤是我国煤炭消耗中的主要组成部分,排放大量的温室气体;在低碳经济模式下,征收碳税将成为实现低碳的一种重要手段.本文通过构建火电行业的利润最大化模型,采用比较静态分析方法分析了碳税对我国火电行业产业的影响.结果表明:1)碳税税率A的增加,火电行业的生产成本(碳税)将增大,为了获得最大化利益,火电企业将采取措施降低碳排放量,减少支出;2)降低碳排放系数α,增加发电机组、人力、物流运输等投入,更新机组,采用低碳能源发电,减少碳税成本.Used in power generation, coal is one of the most important energy in Chinese energy con- struction. Lots of greenhouse gases are produced during the power generation. Under the low-carbon e- conomy environment, taking the carbon tax is an important mean to achieve low-carbon purpose. By con- structing profit-maximizing model, the article discusses how the carbon taxes impact Chinese coal industry by using comparative static analysis. The result indicate that： 1） as the rate of carbon tax, A, is in- creased, the thermal power companies will reduce the carbon emissions to get the maximized profit for the production cost is a/so increased. 2） by decreasing the carbon emission factor a, increasing the investiga- tion of generators, manpower and transportation, and using low-carbon energy in generation, the cost of carbon tax will be reduced.
