【摘要】：从投入产出角度,在采用主成分分析提取投入产出主成分的基础上,运用超效率三阶段DEA模型,修正了环境变量与随机因素的影响,对2013年中国各省域的综合运输效率进行测算,最后采用空间自相关检验和空间散点图分布分析了我国综合运输效率的空间集群特征。结果表明:1剔除外部环境变量和随机因素等影响后,我国总体综合运输效率有所下降(调整前0.87→调整后0.74),呈现东部高、中部次之、西部效率低的空间格局;2调整前后,我国均有10省域处于运输效率前沿面,调整前后效率最优的省域分别为广东(调整前4.34→调整后1)、天津(调整前0.72→调整后1.15),效率最低的省份为西藏(调整前0.06→调整后0.05);3我国各省域综合运输效率存在空间正相关性和空间集聚效应,主要表现为低低聚集,高效率地区聚集效应不显著。
[Abstract]:From the point of view of input and output, on the basis of principal component analysis (PCA) to extract the principal components of input-output, the effect of environmental variables and random factors was modified by using the super-efficiency three-stage DEA model. The comprehensive transport efficiency of Chinese provinces in 2013 was measured. Finally, spatial autocorrelation test and spatial scatter plot distribution are used to analyze the spatial cluster characteristics of China's integrated transport efficiency. China's overall integrated transport efficiency has declined (0.87 before the adjustment). 鈫扐fter the adjustment, the spatial pattern was high in the east, followed by the middle, and low efficiency in the west. 2 before and after the adjustment, 10 provinces in China are in the front of transportation efficiency, and the most efficient provinces before and after adjustment are Guangdong Province (4.34 before the adjustment). 鈫扐fter adjustment, 1, Tianjin (0.72 before adjustment). 鈫扐fter adjustment, 1.15% of the provinces with the lowest efficiency are Tibet (0.06 before the adjustment). 鈫扐fter adjustment, there exists positive spatial correlation and spatial agglomeration effect in the comprehensive transportation efficiency of different provinces in China, which is mainly shown as low concentration, but not significant in high efficiency areas.

【正文快照】： 综合运输效率是衡量整个运输系统运行状况和资源配置效果的综合性指标,是运输资源配置效率的重要反映。国外学者对运输效率的研究较早,1970年代,Costa、Fielding、Gilbert等构建了不同的评价指标体系,借助神经网络等模型对城市的公共交通效率进行评价[1-3];Apostolides采用Tor
