摘要:

城市群是区域经济发展的全球化趋势,综合交通系统是其基础条件.在构建综合交通运输系统承载力、协调性的结构模型后,讨论了数据包络分析(DEA)方法建模特点及带非阿基米德无穷小参数DEA模型求解思路.用DEA模型定义了综合交通系统基础设施、经济发展、潜在需求的承载力,以及系统协调效度、发展效度、综合效度.考虑各运输方式投入产出机制的共性与差别,利用DEA方法对输入输出数据去量纲处理的特点,选取了有别于一般的输入输出指标进行评价.以海西城市群为例的评价结果反映出的变化规律与实际情况一致,表明模型构建及指标选取有效.

Abstract:

Urban agglomeration (UA) is a global trend of the regional economic developing, and the integrated transportation (IT) system is a vital supporting fundament for UA. Two structure models of capacity and coordination in the IT system are composed firstly, and the data envelopment analysis (DEA) is selected as an evaluating method. The solving path of DEA model with non- Archimedes infinitesimal parameter is discussed. Then, the DEA method is used to define the capacity of infrastructure, or economic development and potential demand, as well as the validity of coordination, validity of development, and comprehensive validity in IT system. Considering the similarities and differences among various inputoutput mechanisms, and using the advantage of nondimensionalized-data processing in DEA, some indexes, great distinct with those of general, are selected. Finally, the calculated results from the IT system of Haixi UA show that reflected changes from the example are consistent with the real situation. It proves the models and indexes are powerful.

Key words: integrated transportation, carrying capacity, coordination, data envelopment analysis, urban agglomeration
