通过构建城市效率评价指标体系,采用DEA交叉评价模型对处于西北干旱区的甘肃河西地区5个地级市的城市效率进行评价研究,以克服传统DEA无法区分有效单元之间的优劣.结果表明:河西地区城市效率总体水平不高,工矿型城市效率高于非工矿型城市,人口规模与城市效率的相关性尚不显著,从规模效率的角度看河西地区的城市目前还具有很大的发展潜力.在此基础上提出了提高河西地区城市效率及城市未来发展的对策.
通過構建城市效率評價指標體繫,採用DEA交扠評價模型對處于西北榦旱區的甘肅河西地區5箇地級市的城市效率進行評價研究,以剋服傳統DEA無法區分有效單元之間的優劣.結果錶明:河西地區城市效率總體水平不高,工礦型城市效率高于非工礦型城市,人口規模與城市效率的相關性尚不顯著,從規模效率的角度看河西地區的城市目前還具有很大的髮展潛力.在此基礎上提齣瞭提高河西地區城市效率及城市未來髮展的對策.

An urban e?ciency evaluation index system was established and the urban e?ciency of 5 cities in the Hexi corridor was evaluated based on DEA cross-evaluation model, for the purpose of distinguishing the advantages and disadvantages between the decision making units. The results show that general level of urban e?ciency of 5 cities in the Hexi corridor is not so high and has not achieved the desired state;the urban e?ciency presents a diminishing trend from the mining-based cities to non-mining-based cities; urban e?ciency and city size are positively related; the correlation between urban population size and urban e?ciency is not significant and, in an overall sense urban e?ciency and city size are negatively correlated. The comparative analysis results show that the urban e?ciency of the Hexi corridor presents a rising tendency. In order to increase the urban e?ciency and promote the future development of cities in the Hexi corridor, some optimization measures are given at the end of the paper based on the above analysis.
