中文摘要：

核心城市与周边城市的经济联系潜力可以反映经济区的发育程度.利用2012年河南省的省会、中原城市群的核心城市郑州和周边8个城市的非农业人口、地区生产总值、高速公路距离,运用引力模型来计算城际经济联系潜力.利用资本形成总额、国内生产总值、地区职工工资总额、地区国内生产总值、第二产业总产值、第三产业总产值数据,根据测度地区间地缘经济关系的方法—欧式距离,分析郑州市地缘经济关系对开展区域合作的重要作用,对郑州与中原城市群其他8个城市的地缘经济关系进行定量分析.结果得出：从经济联系潜力上看,周边8个城市与郑州市均呈强度等级.从地缘经济关系上看,许昌、漯河、济源三市与郑州表现为强互补型地缘经济关系;平顶山市与郑州表现为弱互补性地缘经济关系;焦作市与郑州市具有不明确型的地缘经济关系;开封、新乡两市与郑州具有一般竞争型地缘经济关系;洛阳市与郑州市具有强竞争型地缘经济关系.最后提出区域合作发展策略.

英文摘要：

The economic contact potential between the core city and surrounding cities can reflect the degree of development of economic zone. Using the capital of Henan Province, the core city of Zhengzhou and the nonagricultural, the GDP and the motorway of surrounding eight cities, we use the gravity model to calculate the inter urban economic contact. Geo-economic relation, which is categorized into complementary ones and competitive ones, influences regional economy through the inter connection of local geography, economy, politics, culture and social custom. As the most important city among the Central Plains Urban Agglomeration, Zhengzhou has the advantages of regional cooperation in multi-position with other eight cities. This article, based on the geo-economic measuring tool, namely the Euclidean distance model, measures and assesses the geo-economic relationship between Zhengzhou and other cities in the Central Plains Urban Agglomeration. Finally, the article proposes the development strategy for regional cooperation in accordance with the results of quantitative analysis.
