【摘要】 在曾绍伦等人(2009)的研究基础上,针对多个决策单元同时处于效率前沿的情况,使用传统BCC和超效率BCC,评价了基于环境约束视角的燃煤电厂经营绩效,就如何在现有技术条件下稳步推进污染减排计划提出建议.研究认为:无论从传统BCC模型还是超效率BCC模型来看,标号为9和10的燃煤电厂的经营绩效都处于前列,是其他燃煤电厂效法的标杆,而标号为7的燃煤电厂的经营绩效最差;在现有技术水平条件下,推进污染减排计划将不可避免地带来经营绩效的下降,稳妥的计划推进路径应该是"废水→粉煤灰→SO2→烟尘→NO2".更多还原

【Abstract】 With the research foundation of Zeng et al.(2009),and given many DMUs on the frontier at the same time,both the traditional and the super efficiency models were used to evaluate the operational efficiency of coal-fired power plants from the perspective of environmental restriction,and the proposal to promote pollution reduction was also given.The results suggest that both power plant 9 and 10 have the best efficiency performance,which are the benchmarks of the other coal-fired power plants,while power plant 7 shows the worst performance.Given the current technology to promote pollution reduction will low the efficiency inevitably,while "wastewater→flying ash→SO2→smoke&dust→NO2"should be the best and safe path to be.更多还原
