运用空间经济学理论与方法,通过空间极化评价指标,分析延边地区内外部经济空间极化特征和趋势。分析结果显示,1985—2009年,吉林省内增长极得到强化,逐渐形成长春和吉林双核心的增长极。延边地区受到来自区域内的极化效应影响,经济增长速度相对缓慢。延边地区内部,以延吉为经济增长极,但经济资源聚集总量过少,难以发挥区域规模经济。 Using the theory and method of space economics, this paper analyzes the polarization characteristics and trends of the economic space inside and outside Yanbian through spatial polarization evaluation index. The results of the analysis show that in 1985-2009, the growth pole in Jilin Province was strengthened and a dual-core growth pole in Changchun and Jilin was gradually formed. The Yanbian area is affected by the polarization effect in the region, and its economic growth rate is relatively slow. Yanbian region to Yanji as the economic growth pole, but the total amount of economic resources gathered too small, it is difficult to play a regional economies of scale.
