中原城市群空间经济联系结构及其演变特征

The Spatial Economic Linkage Structure of the Central Plains Urban Agglomeration and its Evolution Characteristics

以中原城市群为例,应用城市群空间经济联系模型中的引力模型和区位度模型,分析中原城市群1995—2015年30个城市间的经济联系强度及区位度的时空演变特征.研究结果表明:近20年来,中原城市群以郑州为核心带动周围其他城市发展的趋势较为明显. 1995—2005年和2005—2015年各城市间的经济联系强度分别以6. 1倍和3. 8倍的速度增大,城市之间的空间联系逐渐加强,联系规模不断扩大. 1995—2015年中原城市群各城市间的区位度差距逐渐减小,呈现以郑州为中心的一体化发展趋势.

Taking the Central Plains Urban Agglomeration as an example,the gravitational model and the location model in the spatial economic linkage model of urban agglomeration are used to analyze the spatial and temporal evolution characteristics of the economic linkage intensity and location of the 30 cities in the Central Plains Urban Agglomeration from 1995 to 2015. The results show that in the past 20 years,the trend of the Central Plains Urban Agglomeration with Zhengzhou as the core to promote the development of other cities around is quite obvious. In 1995-2005 and 2005-2015,the intensity of economic linkages between cities increased by 6.1 times and 3.8 times respectively. The spatial connection between cities has gradually strengthened,and the scale of contacts has continued to expand. From 1995 to 2015,the location disparity between cities in the Central Plains Urban Agglomeration has gradually decreased,showing an integrated development trend centering on Zhengzhou.
