协同发展视角下长春经济辐射力研究

Research on Changchun’s Economic Radiation Capacity from the Aspect of Coordinated Development

通过引入经济重心模型、引力模型及断裂点模型,结合因子分析法及GIS软件分析图,研究吉林省2002—2016年经济重心迁移位置及经济重心城市对周边城市的经济辐射力度。结果表明:2002—2016年期间,吉林省经济重心一直徘徊在长春境内,较为稳定,可确定长春市作为吉林省中部城市群经济增长极的重要地位。长春市对吉林市的引力值和断裂点距离影响均较大,吉林市可作为吉林省副增长极城市。随后是四平市和辽源市,其他城市受经济辐射力影响一般,松原市经济后发优势显著,经济辐射距离大于城市间距离。因此,积极发挥长春市经济增长极作用、促进吉林省中部城市群协调快速和共同发展是亟需解决的问题。

Based on the economic gravity model,gravity model and breakpoint model,combined with factor analyzing method and GIS software,the paper analyzed the relevant economic indicators of Jilin Province from 2002 to 2016. The results show that from 2002 to 2016,the economic center of gravity of Jilin Province is stable and hovering in Changchun. Changchun is the economic growth pole of Jilin Province. The gravity value and the breakpoint distance show that Jilin City is affected strongly by Changchun,following it is Liaoyuan and Siping City,the others are affected more generally,furthermore, Songyuan City has the advantage in the future. Overall,Changchun play an actively growth pole in economic growth,coordinating the urban agglomeration in-Jilin Province developing harmoniously is urgency.
