Jacquemin-Berry熵指数可以把金融产业总集聚程度分解为区域间集聚程度和区域内集聚程度。分解结果表明,1979-2010年间中国金融集聚程度经历了先下降后上升的过程,从总体上看是上升的,并且上升的主要原因来源于区域间集聚程度。中国金融总集聚水平的上升很大一部分原因是由于金融资源向东部转移造成的。利用单位根检验和协整检验对金融集聚与区域经济增长差距之间长期因果关系的经验分析表明,金融集聚与区域经济增长差距之间具有前者推动后者的单向长期因果关系。
Using Jacquemin-Berry entropy index, the total agglomeration level can be divided into inter-region agglomeration and inner-region agglomeration. Results show that over 1979-2010 the extent of financial agglomeration decreased first, and then rised, and on the whole it was rising. The rise of total financial agglomeration level mainly comes from the rise of the ex- tent of inter-region financial agglomeration. The rise of China’s financial industrial agglomeration is due to the transfer of financial resources from other regions to the east. Using the unit root tests and cointegration, we find there is a unidirectional long-term causality relationship between financial agglomeration and regional economic gap.
