摘要
沈阳经济区作为国家新型工业化综合配套改革试验区,对其区域差异的研究具有重要的意义。通过研究区域自1992年以来经济重心的动态演化过程,得出该地区经济发展县际差异的动态变化规律,并且就其演化的机制因子进行了分析。研究表明:沈阳经济区经济重心主要介于沈阳市苏家屯区和辽阳市灯塔县之间,基本接近几何中心,并与几何中心的距离呈现不断缩小的趋势,表明区域经济发展的不平衡性在减弱。19年来,经济重心总的移动趋势为先由东北向西南移动,再由西南向东北推进,但移动轨迹呈现出一定的曲折和波动,其年移动距离和方向与区域经济发展水平、速度及政策等显现正相关关系,反映出区域不同时期发展战略政策的变化。
Based on the application of the methods of spatial analysis, with taking Shenyang Economic Zone as the object of study, this article introduces the concept of regional gravity center, analyses the temporal evolution of the internal economic center of gravity and the trace of evolution from 1992 to 2010, reveals the dynamic changes of economic development and the question of unbalanced spatial development, then discusses the causes of economic gravity evolution and driving mechanism. The results of the study are as followed： （1） the economic center of Shenyang Economic Zone mainly distributed in between Shenyang Sujiatun District and Liaoyang Dengta County close to the geometric center. It has obvious phase characteristics moving from southwest to northeast. In terms of latitude and longitude direction, the moving process of economic gravity presents the obvious non-constant velocity characteristics, especially in the year 2003--2006; （2）mobile phase of the Shenyang Economic Zone economic center has a distinct signature. Compared with the geometric center, it is far from the economic center and then close to it later. This character indicates that the disproportion economic development of Shenyang Economic Zone is weakening, that is consistent of the reality of economic development; （3） for 19 years, the mobile trend of economic center of Shenyang Economic Zone moves from northeast to southwest, then moves from southwest to northeast, but the moving track is tortuous. Its annual moving distance and direction has a positive correlation with regional economy development level, speed and policy, showing the changes of development strategy and policy in different period and the strategic orientation of economic development in Liaoning province and Shenyang City.
