The Spatio-Temporal Evolution Characteristics and Mechanism of Yangtze River Delta City Logistics Development Efficiency
基于2002-2011年投入产出数据，用DEA方法分析长三角城市物流效率的演化趋势、结构及空间格局，发现效率整体上升但存在规模不经济，且与经济发展水平不匹配。
Based on the input-output index of city logistics,by using the method of DEA and exploring statistics,the paper has tried to analyze the whole evolution trend,structure and spatial pattern’evolutionary process and its evolutionary mechanism of Yangtze river delta City logistics development efficiency from 2002 to 2011.The analysis shows that: 1) the whole efficiency of Yangtze River delta City logistics development is increasing from 2002 to 2011,but there is a plenty of developing space for production factors and the Logistics industry investment is still in diseconomies of scale. 2) Each city logistics development efficiency shows the different features,and it can’t keep balance with the city’s economic developing level. 3)Spatial heterogeneity of logistics development efficiency in Yangtze River delta City is enhanced,but the coastal port cities and comprehensive transportation hub cities show the high efficiency of logistics development. The study suggests that: Location advantage base,economy policy,industrial transition and upgrade,investment of infrastructure construction,the progress of technology and consumption need’s stimulation promote the transformation of spatial pattern of city logistics development efficiency.
