在区域空间结构发展模式中,极核式空间结构占有重要地位。本文从宏观和微观的不同视角,以天体、原子等自然观类比区域经济发展中的极核关系,认为极与核无论从空间相对位置,还是从各自的功能特点来看都具有一定的差异,并在研究极核关系的基础上,探讨极核关系形成的原因、演化规律及极核体系的形成。 In the pattern of regional spatial structure development, polar nuclear space occupies an important position. From the perspectives of macroscopic and microcosmic, this paper takes polar relations in the economic development of analogy regions such as celestial bodies and atoms, believing that the polarities and nuclei have some differences in terms of relative spatial position or their respective functional features. Based on the study of polar-nuclear relationship, this paper explores the formation of polar-nuclear relationship and the formation of polar-nucleus system.
