摘要
主要针对如何测量石化企业环境绩效进行了研究。为兼顾企业的经济利益与环境绩效,引用了生态效率的概念,并在此基础上提出了能源生态效率和环境生态效率的概念。在计算方法上,尝试根据特征污染物对环境的影响程度计算权重系数,再分别计算水、气、固废的环境影响,最后采用数据包络分析方法计算生态效率、能源生态效率和环境生态效率。
This paper studies on how to calculate the petro- chemical enterprises' environmental performance. In order to assure the enterprises' economy benefit and environmental performance, it cites the conception of ecology efficiency, and offers the conceptions of energy ecology efficiency and environmental ecology efficiency based the ecology efficiency. It attempts to calculate the weighted coefficient according to the environmental impact of character pollutants. Then, it calculates the environmental impact of water, gas and solid waste. At last, it uses the data envelopment analysis method to calculate the ecology efficiency, energy and environmental ecology efficiency.
