摘要
一、极化效应与扩散效应理论区域经济成长在其空间结构演变上,始终存在着两种效应:即极化效应和扩散效应。二者既相互依存,又相互制约,并在一定条件下相互转化。极化效应使区域经济从孤立、分散的均质无序状态,走向局部聚集不平衡发展的低级有序状态。扩散效应则使聚集逐步向全区域推进,终而走向区域经济相对均衡发展的高级有序状态。极化与扩散效应的相互作用,是区域经济空间结构演变的主动因,其作用的结果,使区域经济空间不断扩大,非经济空间逐渐变小,生产部门、生产要素、生产环节的空间组合日趋复杂化和多样化。这是不以人的意志为转移的区域经济成长的一般过程和规律。
Polarization effect, diffusion effect and their mutual action are the main reasons ofregional economic space evolution. Bothactionstrength and way are quite different at different regional growth periods. Regional economic growth experiences three periods : (1) disperse even unorderly state; (2) part gath-ering and imbalanced development low - orderly state;(3) diffusion and relative balanced development high -orderly state. China is situated in the initial stage of regional economic growth, and its enormous regional differences are impossible to be eliminated in a short time.
