从发生学角度试图证明,区域空间结构模型由区位论、双核论、海港论3大理论所组成,分别基于内生型、过渡型、外源型的区域发展背景。具体而言,均质平原是上述3个理论共同的假设条件,其实也是所有区域空间结构模型提炼的必要条件,但充分条件则各不相同。区域发展过程的不同,衍生出不同的区域空间结构形态及相应的区域空间结构模型。由此,至少从发生学角度而言,这3个理论模型构成了区域空间结构模型的基本理论体系框架。区域双核结构模式的理论地位也得以科学地确立。
From the point of view of genesis, it is tried to prove that the model of regional spatial structure is composed of three theories of location theory, dual-core theory and seaport theory, respectively based on the endogenous, transitional and exogenous regional development background. Specifically, Homogeneous Plains is a common assumption of the above three theories, which is actually a necessary condition for the refinement of all regional spatial structure models, but the sufficient conditions are different. Different regional development process leads to different forms of regional spatial structure and corresponding regional spatial structure models. Thus, at least from the perspective of genetics, these three theoretical models form the basic theoretical framework of the model of regional spatial structure. The theoretical status of regional dual-nuclear structure model has also been established scientifically.
