投入产出理论与DEA方法的结合使用,为评价各个系统的投入产出效率提供了重要的理论依据和技术手段,同时在当今社会,安全投入产出的研究也越来越重要。因此,本文对近期的相关文献进行了总结整理,发现基于DEA的投入产出模型应用广泛,但基于DEA模型的安全投入产出评价模型还处于发展的初级阶段,应用范围狭窄。
The combination of input-output theory and DEA method provides important theoretical basis and technical means for evaluating the input-output efficiency of each system. At the same time, the research of safety input-output is more and more important in today’s society. Therefore, this paper summarizes the recent literature and finds that the input-output model based on DEA is widely used. However, the evaluation model of safety input-output based on DEA model is still in the initial stage of development and has a narrow application scope.
