新经济地理学视角下电子商务对人口流动的影响

The Influence of E-Commerce on Population Flow in the Perspective of the New Economic Geography

通过对新经济地理学中的线性模型加以修改,本文将跨区域交易的商品种类增加了服务品,修改冰山运输成本为更合理的单位可变成本,最后建立大-小城市模型,使用区域间相对吸引力来描述人口流动的方向与强度。通过数值模拟分析,本文得出结论,电子商务的发展使得服务品提供方式多样化,加上电子商务带来的跨地区交易成本降低,有利于增强中小城市对人口的吸引力。文章最后指出,电子商务的发展有利于改变我国区域人口不平衡的现象,但在短期内不平衡仍将存在。

By amending the linear model of New Economic Geography,this paper adds service products to the category of cross regional trading,turns iceberg transport cost into more reasonable variable cost,finally builds big and small city models and describes the direction and strength of population flow by the relative interregional attraction. By numerical simulation analysis,this paper draws the conclusion: the development of e-commerce makes the providing means of service products diversified. It is conductive to strengthening the attraction of small and middle cities to population. Finally,this paper points out that the development of e-commerce is conductive to changing the regional population imbalance phenomenon of China but in the short term,the imbalance still exists.
