文章建立了低碳经济背景下的铅锌企业低碳生产水平评价指标体系,并同时结合BP网络和DS证据理论的优点与最新研究成果,提出了我国铅锌企业低碳生产水平的“DS-BP”评价模型。实证检验表明:该模型具有很好的有效性和普适性,能有效避免和改善现有其他评价方法难以面对的“信息残缺”、“信息模糊”和“信息容错”等问题,从而从一个崭新的角度较好地解决了铅锌企业低碳生产水平评价问题,为铅锌企业低碳战略的制定及实施提供了一种有用的分析工具和决策支持。
The paper establishes a low carbon production level evaluation index system for lead and zinc enterprises under the background of low carbon economy. At the same time, combining the advantages of BP network and DS evidence theory and the latest research results, -BP “evaluation model. The empirical test shows that the model has good effectiveness and universality, and can effectively avoid and improve the ”informational defects“, ”information ambiguity“ and ”informational fault tolerance“ that other existing evaluation methods are difficult to confront. ”And other issues, so as to solve the low-carbon production level evaluation of lead-zinc enterprises from a brand-new perspective and provide a useful analytical tool and decision support for the formulation and implementation of low-carbon strategies for lead and zinc enterprises.
