在应用数据包络分析方法进行评价时,要求所有指标必须具有偏好性,即所有指标必须越大越好或者越小越好.然而,当评价指标体系中含有中性(即没有偏好性)指标时,传统的数据包络分析方法则不能解决该类问题.因此,本文以经济效率与产业结构调整为背景,从系统性的角度出发提出了一种用于评价含有中性指标的数据包络分析模型.该模型不仅能给出一个经济系统的效率大小,而且还能给出该系统应如何通过产业结构调整来提高经济系统的效率.最后,应用本文提出的方法分析了天津市经济结构调整的有效性问题.
In the application of data envelopment analysis for evaluation, it is required that all indicators must have a preference, that is, all indicators must be bigger and better or smaller as possible.However, when the evaluation index system contains a neutral (ie, no preference) indicator , The traditional data envelopment analysis method can not solve this kind of problem.Therefore, in the context of economic efficiency and industrial restructuring, this paper presents a data envelopment analysis for evaluating neutral indicators Model.The model can not only give the efficiency of an economic system but also give the system how to improve the efficiency of the economic system by adjusting the industrial structure.Finally, using the method proposed in this paper, the author analyzes the economic structure adjustment of Tianjin Validity question.
