【摘要】:空间界面理论已显示出强大生命力,但其理论架构还不完善。现有研究基本上是建立在"空间界面确实存在"这一经验判断的前提下进行的,对于其存在性还缺乏理论验证。在提炼空间界面唯象理论的基础上,构建了空间界面的数理模型,并以城乡界面为例,以空间为内生变量,空间中的元素如经济、社会、文化等为外生变量,构建联立方程模型,以河南省108个县域为空间单元,采用三阶段最小二乘法和迭代三阶段最小二乘法进行参数估计,建构了城市系统和乡村系统的函数,并进行了数理推导与求解。研究表明,城市函数与乡村函数存在着交集,且其交集为无穷多个点组成的域面,即存在一个城市与乡村系统空间及其要素相互交织而成的独立系统,进而从理论上证明"城乡界面是存在的"。
[Abstract]:The theory of spatial interface has shown great vitality, but its theoretical framework is not perfect. On the basis of abstracting the phenomenological theory of spatial interface, the mathematical model of spatial interface is constructed. Taking the urban and rural interface as an example, the space is taken as an endogenous variable, and the elements in space such as economy and society are taken as examples. Taking 108 counties in Henan Province as spatial unit, the paper constructs a simultaneous equation model by using the three-stage least square method and iterative three-stage least square method to estimate the parameters, and constructs the functions of urban and rural systems. The results show that there exists an intersection between the urban function and the country function, and the intersection is a domain of infinitely many points. That is, there is an independent system which interweaves urban and rural system space and its elements, and proves theoretically that "urban-rural interface exists".
