摘　　要：城市竞争能力的强弱决定着城市的兴衰。全球流动的资本、创新知识与技能、高级人才、旅游者等都是当今经济全球化趋势下城市发展的宝贵要素,这些要素的有限性使城市之间的竞争愈加激烈。以省域城市群为背景区域,研究城市竞争力的评价与时空演变,对于完善我国城市竞争力研究体系、整合城市群各城市具有重要意义。本文建立了中原城市群城市竞争力评价的指标体系,运用主成分分析法评价1988年、1992年、1998年和2006年中原城市群的城市竞争力,进而研究了城市竞争力的时间演变和空间演变,计算了4个时间断面上中原城市群九城市的城市竞争力主成分得分与综合得分,并据此对城市竞争力进行评价、排序。根据评价结果揭示了中原城市群城市竞争力的总体演变、主成分演变和影响因素演变的规律与特征。通过分析不同时间断面上的城市竞争力等级分布图和插值效果图,揭示了中原城市群城市竞争力的空间分异和空间扩展的演变规律与特征。The paper established an evaluation index system of the city competitiveness of Zhongyuan Urban Agglomeration, and used principal component analysis to evaluate the city competitiveness in 1988, 1992, 1998 and 2006, respectively. Moreover, the paper studied time evolvement of the city competitiveness. The index system includes basic com- petitiveness, economic competitiveness, science and technology competitiveness, opening competitiveness, government function, environment competitiveness, and 15 element layer indexes, as well as 40 basic variable layer indexes. In actual problems, it is common that several maximal principal components are selected. The paper used calculated results of the city competitiveness, space expression method and space interpolation method to research space evolvement of the city competitiveness of Zhongyuan Urban Agglomeration. According to comprehensive scores, the cities are divided into four grades, 〉1.5, 1.5 to --0.5, --0.5 to --2 and 〈-2. Cities in different grades are expressed in the map of Zhengzhou Urban Agglomeration with different colors, and the evolution situation of spatial differentiation of the city competitiveness is expressed through different time sections. The paper selects brief and exact spatial interpolation method--IDM （Inverse Distance Weighted） to research the evaluation situation of spatial patulous of the city competitiveness. Numerical value of interpolation points that are calculated will be automatically created in the city competitiveness map, and the effect maps are formed about the city competitiveness. According to the analysis result, the basic points of view are obtained as follows： （1） Principal component and comprehensive scores of the city competitiveness of nine cities for four time sections were calculated, and the city competitiveness was evaluated and sorted. （2） According to the evaluation result, the rules and features of general evolution, principal component evaluation, influencing factors in evolution of the city compet
