中文摘要：

运用SPSS和Arc GIS分析技术,从城市职能互补和水平联系两种关联机制入手,对中原经济区2004,2009,2014年城市之间相互关联特征展开研究。结果表明：（1）中原经济区各个城市之间职能互补性不强,且城市潜在的职能互补性不断减弱,多数城市趋于综合化发展,九大职能部门中仅采掘业表现出专业化发展的趋势,其他职能部门均趋于综合化发展;（2）水平联系格局以郑州和邯郸为中心,中原城市群城市之间的联系强度大于其他两类区域（中原城市群以外主体区和中原经济区非主体区）,呈现出“中心-外围”的空间格局;（3）从经济因素、区位因素、政策因素3个方面对中原经济区城市相互关联格局的形成进行了分析。

英文摘要：

Using SPSS and ArcGIS to research the correlation of cities of Center Plains Economic Region in 2004, 2009 and 2014 from functional complementation and horizontal connection. Firstly, cities functional comple- mentation of Center Plains Economic Region is very weak and the potential functional complementation of cities is continue reduce, most cities tend to be more comprehensive development. In addition, only extractive industry shows the development trend of specialization in nine function department, other function departments tend to be more comprehensive development. Secondly, horizontal connection pattern presents dual core development model with the center of Zhengzhou and Handan. The connection between the city of Zhongyuan Urban Agglomeration is greater than the other two kinds of area, and presents the spatial pattern of ＂core-periphery＂. Finally, from eco- nomic factors, location factor, policy factor to analysis the correlation pattern of Center Plains Economic Region.
