在对区域经济空间极化相关文献研究综述的基础上,借鉴有关研究方法,遵循从过程到格局、机理,从整体到局部的研究思路,首先以人均GDP为测度指标,综合分析东北三省及其内部各区域经济差异与空间极化的过程与空间格局,接着以人均GDP的极化水平为应变量,以工业总产值、当年实际直接利用外资额、社会商品零售总额、全社会固定资产投资、全员劳动生产率和复合流量的极化水平为自变量,建立多元线性回归模型,分析区域经济空间极化的内在机理。结果表明:①区域经济发展存在空间极化现象,且整体呈现出南强北弱的态势;②哈长经济区和辽中南经济区已初步形成,其中哈长经济区处于明显的集聚阶段,而辽中南经济区扩散效应已开始发挥作用;③地区经济发展的位序排名及其变化表明区域经济发展中心逐步南移;④区域差异和空间极化总体变化趋势基本一致,呈现出先升后降,但总体水平呈上升的变化态势;⑤多元线性回归模型表明各动力因子的作用程度和作用趋势不尽相同,但工业总产值和全员劳动生产率是东北三省及其内部区域经济空间极化演变所共有的主导驱动因子,说明其区域经济发展是一个内生增长过程,并提出应强化市场体制转轨、国有企业改组改革、产业结构升级换代和政府政策的导向作用。

This paper uses some of the related analysis methods for reference to comprehensively analyze the regional economic differences and the spatial polarization of the Northeast of China and their inner areas The result shows that:(1) the regional economic development appears spatial polarization,and on the whole,it appears weaker in the north and stronger in the south; (2) Ha-Chang economic zone and central-south of Liaoning economic zone have initially taken shape,while central-south of Liaoning economic zone has begun to play a role in diffusion effects; (3) the order and its changes of the regional economic development show that the development centre has gradually moved to the south; (4) on the wholly,the evolution trend of the regional differences and spatial polarization have a common that ascending at first and reducing at last,but the whole level has increased; (5) the multivariable linear regression model indicates that these driving factors have a different effect degrees,the role of trend,but the gross industrial output value and the productivity of staffs are the same factors that dominant the Northeast of China and its inner areas' regional spatial polarization. From this perspective,the three northeastern provinces and internal regions achieve integrated development should break up present industrial system which takes state-own enterprises as a main manifestation,takes heavy chemical industry as main contents,takes old industrial bases as basic point to layout,and develop township enterprises,private economy and light industry,from pattern,content and form to achieve it.
