城市群时代中心城市的影响腹地界定研究——以济南市为例

STUDY ON THE HINTERLAND AREA OF CENTER CITIES IN URBAN AGGLOMERATIONS ERA——A Case Study of Jinan

进入21世纪,我国进入城市群快速发展时期,而中心城市的辐射和带动是城市群形成发展的重要基础。本文以济南市为例,通过构建多指标体系,在测算城市中心性强度值的基础上,利用扩展断裂点模型在GIS软件支持下勾勒济南在区外、区内两个层次的影响腹地范围。研究表明:受不同城市作用力影响,济南在区外城市间的影响腹地范围基本吻合山东省西部行政边界,与当前济南都市圈的范围基本一致;而区内腹地范围明显大于济南行政区划,形成了中心城市的高地效应。结合研究成果,对济南城市发展提出诸如合理调整行政区划、改善基础设施和加强都市圈建设等发展建议。

In 21 st Century, China entered a period of rapid growth of agglomerations based on the radiation from center cities. At the same time, regional hinterland is the development foundation of center city. So it is very important to measure the radiation ability and hinterland of center city. Taking Jinan city as an example, based on calculation of central-strength values with index system which includes 16 indicators, urban hinter- land of Jinan is defined by applying of the extended breaking point theory. Then, comprehensive countermea- sures are put forward to promote health growth of Jinan. Results show that the extended breaking point theory is a good method to define the hinterland of center cities. Hinterlands of Jinan are different by effect of differ- ent cities. As the core city of a regional agglomeration, the actual radiation function of Jinan is too weak to promote quick development of Jinan agglomeration. Jinan is sixth in the 10 center cities for comparison al- though it is first in Jinan agglomeration Therefore, it is necessary to increase the central-strength value of Ji- nan and improve the radiation driving force for regional development. Comprehensive countermeasures should be implemented. First of all, rationally readjusting of administrative division is necessary to meet the need of Jinan because its jurisdiction area is too small and the shape is not suitable for its function. Secondly, infrastructure such as transportation should be improved and integrated to expand the channel of radiation to promote the industrial division and cooperation. And finally, comprehensive competitiveness of Jinan should be strengthened by transfer of developing mode and industrial structure to foster a powerful center city to lead rapid development of Jinan agglomeration.
