摘要
将电网投资所取得经济、环境、社会效益分别作为超效率数据包络分析法的输出,电网发展中的人、财、物三方面选取其输入指标,分别计算经济、环境、社会效益的投资子效率。运用熵权法和专家法计算得到的子效率权重计算电网投资综合效率,运用斯皮尔曼等级相关系数对电网投资效率影响因素进行定量分析,找出其中的关键因素,据此制定投资效率优化措施。以某区域电网为例进行分析计算,得到了区域内各省级电网的投资效率,找出了其中的关键影响因素,从而证明了所提方法的适用性和有效性。
Taking the economic ,environmental and social benefits as the output of the super-efficiency data envelopment analysis, the human,financial and material resources as the input of the power grid development, the investment sub-efficiency of economic, environmental, and social benefits are calculated respectively. Finally the expert and entropy method are used to calculate the weights of the sub-efficiency and then the comprehensive efficiency of the power grid investment is gotten .The Spearman rank correlation coefficient is used to do the quantitative analysis of the power grid investment efficiency’s influencing factors ,and find out the key factors, then the improvement measures are given accordingly .The data of five province grids are analyzed to make out the investment efficiencies of each province and also find the key influencing factors to prove the adaptivity and effectivity of the proposed method.
