| 摘 要： | 以我国15个副省级城市为研究样本,首先构建了基于效率的副省级城市的投入产出评价指标体系,采用超效率的数据包络分析模型,克服了一般文献中由于通常使用数据包络分析的DI,BC2和DEC2R模型,而陷入对有效的决策单元无法做进一步分析评价的困惑,比较客观地评价了1995-2005我国15个副省级城市效率的演变特征:其一,超效率DEA值变化呈倒U字型.且超效率值有趋同性的态势;其二,超效率DEA值大于1的副省级城市数量逐年增多;其三,超效率DEA值整体变化比较稳定,但少数某些城市的超效率值变化剧烈.

| Abstract: | This paper has set up the input-output evaluation index system of China's 15 sub-provincial cities based on the efficiency. The simple model of DEA,such as C2R and BC2 model,are compared with super-efficiency model of DEA first in this paper,and then 15 sub-provincial cities in China are evaluated by the three models. The results indicate that super-efficiency model of DEA has advantages in the use.The evolution characteristic of 15 sub-provincial cities' efficiency are conclused that:firstly,the changes of... |
