提出采用C~2R模型和C~2GS~2模型相结合的方法测算石化行业相对生态效率,通过应用该模型对石化行业相对生态效率的测算结果分析,进一步验证该模型的实用性、适用性和可行性,为石化行业提供判断、评价行业生态效率的理论工具。测算结果分析表明,该方法有助于发现石化行业企业间经营效率和生态效率的差异,确定企业生态效率的改进方向和目标,有助于开发DEA模型新的应用领域,为相关行业管理者制定可持续发展战略决策提供基础。
The relative ecological efficiency of petrochemical industry is estimated by the combination of C ~ 2R model and C ~ 2GS ~ 2 model. The application of this model to the calculation of relative ecological efficiency in petrochemical industry is analyzed to verify the practicability, applicability and Feasibility for the petrochemical industry to provide judgment, evaluation of the ecological efficiency of the industry’s theoretical tools. The results of the calculation show that the method can help to find out the difference between business efficiency and eco-efficiency among enterprises in petrochemical industry, determine the direction and goal of improvement for eco-efficiency of enterprises, help to develop new application fields of DEA model, Sustainable development strategy to provide the basis for decision-making.
