城市间经济联系的定量计算

城市之间经济联系的准确判断和度量是制定城市和区域发展战略的重要依据.本文考察了空间相互作用模型在实际应用中存在的问题,提出了改进的途径.经济联系是个不可能精确表述的量,本文通过逻辑思辩和数学推导,梳理了相关概念和模型,给出了描述经济联系相对量的表达式.实践证明,本文所提出的模型是可行的,也是比较可靠的,而且我们还发现,经典引力模型中的人口因素并不那么重要.

An attempt to calculate economic links between cities

Right judge and measurement on economic links between cities is the foundation of putting forward the development stratagem of cities or regions. In this paper, some questions about the model of reciprocity in space were talk about, and some methods to resolve them were put forward. It is nearly impossible to describe economic links exactly, but in this paper, some concepts and model were reviewed through logical considering and mathematic deducing, and then the expression of comparative economic links came out . The example in this paper proved that the model put forward was credible and feasible. And we also found that the factor of population in the classic gravitation model is not so important.
