摘要
考虑物流对城市群建设的推动作用,运用DEA模型分析了扬子江城市群8个城市的物流业效率。结果表明:扬子江城市群整体物流效率不高,存在着发展不均衡的现象。具体表现为物流业发展的地区性差异明显,苏南地区的整体物流业效率高于苏中地区;经济发达的城市,物流效率并未都达到DEA有效;非DEA有效的城市,存在着盲目扩大物流规模的现象,表现为扬州等城市物流规模效率无效但规模收益却呈现递减趋势。通过对计算结果的分析评价,提出了扬子江城市群的协调发展优化建议。
In this paper, considering the promoting effect of the logistics industry on the construction of the city group, we used the DEA model to analyze the efficiency of the logistics industry in the eight cities of the Yangtze River city group. The result indicated that the logistics industry was less than efficient and balanced in the city group. It was specifically shown as the significant regional difference in the development of the industry： the overall efficiency was higher in southern Jiangsu than in central Jiangsu; not all economically developed cities reached DEA efficiency; and cities not DEA efficient had the tendency of blind scale expansion as evidenced by the increasingly lower return to scale of cities such as Yangzhou which were low in scale efficiency in terms of the logistics industry. At the end, through the analysis and evaluation of the calculation results, we put forward some suggestions for the coordinated development and optimization of the Yangtze River city group.
