摘要
从城市群公路交通系统的输入和输出角度出发,给出城市群公路交通效率的输入输出指标体系,建立数据包络分析(data envelopment analysis,DEA)模型及带偏好DEA(A-prefer-DEA,PDEA)模型,进而对长株潭、长三角和珠三角城市群公路交通效率进行有效计算和综合评价.传统DEA模型的评价结果表明:长株潭城市群公路交通效率为DEA弱有效,长三角和珠三角公路交通效率为DEA有效;PDEA模型评价结果更直观,长三角、珠三角和长株潭公路交通效率值分别为1.678 2、1.577 9和0.866 2,长株潭公路交通效率与长三角和珠三角的差距比较明显.
The input-output index system of urban agglomeration highway traffic efficiency was provided from the perspective of urban agglomeration highway transportation system based on the input-output aspects, the data envelopment analysis (DEA) model and the A-prefer-DEA (PDEA) model were then established in this paper. Furthermore, the highway traffic efficiency of the three urban agglomerations called Chang-Zhu-Tan, Yangtze River Delta and Pearl River Delta was effectively calculated and comprehensively evaluated. Traditional DEA model shows that the highway traffic efficiency of Chang-Zhu-Tan urban agglomeration is DEA weak efficiency, however, the highway traffic efficiency of Yangtze River Delta and Pearl River Delta are DEA efficient. The evaluation results based on PDEA model are more intuitive, the highway traffic efficiency value of Yangtze River Delta, Pearl River Delta and Chang-Zhu-Tan is 1. 678 2, 1. 577 9 and 0. 866 2, respectively. Therefore, the gap between Chang-Zhu-Tan highway traffic efficiency and those of Yangtze River Delta, Pearl River Delta is apparent based on PDEA model.
