| 摘 要： | 通过建立城市竞争力综合指标评价体系,运用主成分分析计算江淮城市群11个城市在2 001～2 010年4个时间断面上城市竞争力主成份得分和综合得分,并对其进行评价和排序,依据评价结果揭示江淮城市群11个城市竞争力的综合演变、主成分演变特征,进而探究其时空演变趋势。通过分析4个时间断面上的城市竞争力等级分布图和空间插值图,揭示江淮城市群11个城市竞争力的空间分异特征和空间扩展演变规律。

| Abstract: | The paper establishes an evaluation index system of the urban competitiveness for Jianghuai Urban Agglomeration,and uses principal component analysis to evaluate four-year economic data of the urban competitiveness between 2001 and 2010.Moreover,the paper studies time evolvement of the urban competitivement.By using calculated results of the urban competitiveness,space expression method and space interpolation method,space evolvement of the urban competitiveness for Jianghuai urban agglomeration is researched.The paper selects of spatialpatulous of the competitiveness.Numerical value of interpolation points that are calculated will automatically created in the urban competitiveness map,and the effect maps are formaed about the competitiveness. |

| Keywords: | urban competitiveness principal component analysis spatial autoeorrelation spatial-temporal evolvement Jianghuai urban agglomeration |
