基于重力模型的中国金融中心体系识别

Discernment of Chinese Financial Center System： Gravity Model Approach

金融中心是新经济地理学研究的重要领域，金融中心识别是金融中心研究的基础性工作。沿袭金融地理学的分析脉络，从“信息”的角度解释金融中心的形成与演化机制，探究金融中心与信息腹地的关系，以及技术进步和放松管制对不同类型金融中心的影响。引人“重力模型”，将空间要素纳入到金融中心体系识别框架中，对我国金融中心体系进行识别。通过模拟全国、省域两大尺度城市空间金融联系，确定金融中心及其腹地范围，识别并划分我国南、北两大区域金融中心体系，最终得到区域金融中心4个，省域金融中心27个。通过对两大区域体系的对比分析，结果显示南部体系在金融规模、腹地范围、体系结构、发展趋势等四个方面都优于北部体系。

The Financial Center （FC） is one of the most important topics in New Economic Geography, in which the discernment of FC is the primary task and basic work. This paper is focus on the formation and discernment of FC based on the Financial Geography Theory. Firstly, it＇ s discussed that the relationship between FC and its information hinterland to find different effects of technical progress and deregulation on two types of financial center on the basis of information category. Then, geographic element is added to traditional methodology used to only containing scale elements by means of ＂gravity model approach＂. Finally, take China's Mainland as a case to explore the discernment method of FC system, and the results showed as followed： （1）Concerning Chinese FC system, two major regional FC system have formed, the southern system centralized with Shanghai and northern one with Beijing, containing 4 regional FCs and 27 local FCs.（2） Almost every province has 1 or 2 FCs, except Hebei and Inner Mongolia in the northern system, geographical proximity to Beijing.（3）Comparing to Northern system, Southern one have absolute advantage in financial scale, hinterland size, structure complexity and evolution trend, and have formed muti-layer structure inside.
