中国城市投入产出有效性的数据包络分析

The Analysis about Dea-efficiency of China Cities' Input-Output

该文采用数据包络分析 (DEA)有效性方法对我国直辖市和省会城市的投入产出效率进行评价 ,得到的结果为 :西部地区相对于东部地区 ,其投入产出的效率要低得多 ;城市并非规模越大 ,其投入产出越有效。阐明西部地区投入产出方面与东部地区存在一定差距 ,因此 ,西部开发不单是要向西部投入大量资金 ,而是要从改善西部地区的投资环境 ,提高投入产出效率入手。

The aim of this paper is to evaluate input-output efficiency of the China thirty main cities quantitatively. Data Envelopment Analysis (DEA) approach is adopted. The conclusions are: firstly, the input-output efficiency of west region cities is much lower than that of east region cities; secondly, an efficient city should keep a moderate scale. Therefore, the key point about west exploit is to improve capital input-output efficiency.
