基于DEA-CCR模型的交通运输效率评价分析──以浙江省嘉兴市为例

Assessment and Analysis of Transport Operational Efficiency Based on DEA-CCR Model——A Case Study of Jiaxing City in Zhejiang Province

运用数据包络分析法(Data Envelopment Analysis,简称DEA)中的CCR模型,首先确定对交通运输效率分析的决策单元(Decision Making Units,简称DMUs)和输入输出指标体系,其次,以浙江省嘉兴市2001年至2015年期间的交通运输状况为例,通过DEA-CCR模型的建立对其营运效率分别从投入冗余和产出不足两方面进行定量评价,并借助DEA-Solver Pro 5.0数学软件对评价模型进行编程求解,最后分析得到该地区历年来交通运输发展变化特点和趋势,进而提出改善嘉兴市公路及航运运输有效性的建议,为提高交通运输营运效率、协调不同运输方式发展、优化综合运输结构提供了可靠依据。

Using CCR model in DEA, the research makes a quantitative assessment of transport operational efficiency from 2001 to 2015 of Jiaxing city, so that firstly the target system of DMUs in input and output should be determined, and then evaluating the operating efficiency form input redundancy and output deficiency by DEA-CCR model. Then, analyingthis area？ s transpor-tation developmental situation and characteristicsover the years through math software programming and solution. According to the results and analysis,the paper putforwards suggestion about improving the transportation efficiency, whicli provided a re- liable basis for improving transport operational efficiency, coordinating the development of different transport modes and opti-mizing the comprehensive transportation structure.
