为准确评价铁路客运专线的运输效益,采用了比较先进的DEA的C2R模型,计算出经济有效利用率、社会就业带动率两大指标值。所选的投入因子的特征根λi解释了总体方差信息的83.7%,确保了DEA的适用性,进而得到了经济和社会两方面的运输效益综合评价结果。
In order to accurately evaluate the transportation benefit of the railway passenger dedicated line, the C2R model of the more advanced DEA is adopted to calculate the two index values of economic effective utilization rate and social employment-driven rate. The eigenvalue λ i of the selected input factors explains 83.7% of the overall variance information, which ensures the applicability of DEA, and then obtains the comprehensive economic and social evaluation results of transport benefits.
