摘要: 由苏北、皖北、豫东、鲁南4大板块组成的淮海经济区,长期处于经济发展洼地。目前,淮河生态经济带建设正式上升为国家战略,其中北部淮海经济区的建设将促进该区域经济的协同发展。文章通过引力模型,研究淮海经济区城市群的空间结构特征。结果表明,淮海经济区城市综合质量的变化范围为218.16~1 062.58。在淮海经济区内,徐州市对其他城市的引力值最高,但是,徐州市与江苏省、山东省、河南省各城市的断裂点均值相对较大,而对安徽省各城市的断裂点均值相对较小,说明徐州市对安徽省各城市的辐射作用不强。综上得出以下结论:淮海经济区内各城市发展不均衡,徐州市在淮海经济区处于中心城市地位,但是徐州市对其他城市吸引能力有限;徐州市与其他各城市间的经济引力仍存在较大差异;区域内经济往来和交通网络还需进一步完善,不仅要充分发挥徐州市中心城市的辐射功能,还需利用临沂、淮安等次中心城市的扩散作用,促进区域经济的协调一体化发展。

Abstract: Huaihai economic zone, composed of northern Jiangsu, northern Anhui, eastern Henan and southern Shandong, has been underdeveloped for a long time. Now its development upgrades to a national strategy. Construction of the northern part will promote a co-integrated development of the whole zone. This paper uses gravity model to study the spatial structure of urban group of Huaihai economic zone with its results showing a urban comprehensive quality range from 218.16 to 1 062.58. Xuzhou city has the largest gravity within the zone, but has larger fault point average value with Jiangsu, Shandong and Henan, while smaller with Anhui, indicating a weak radiation of Xuzhou to Anhui's cities. Cities in Huaihai economic zone develop at uneven rates with XuHou as the center but with limited attraction and variable economic attractive force to other cities. Economic exchange and communication in the economic zone need to be improved, not only on Xuzhou's radiation, but also on Linyi and Huaian's diffusion as sub-centers, which boosts the integration of regional economy.

Key words: spatial pattern, urban co-integrated development, gravity model, Huaihai economic zone, economic integration
