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。
The Jacquemin-Berry entropy index can decompose the total concentration of financial industry into the degree of regional agglomeration and the degree of regional agglomeration. The decomposition results show that during the period of 1979-2010, the degree of financial agglomeration in China experienced a process of first increasing and then decreasing, and generally speaking, the degree of financial agglomeration increased. The main reason for the increase was the degree of regional agglomeration. A large part of the rise in China’s total level of financial agglomeration is due to the transfer of financial resources to the east. The empirical analysis of the long-term causal relationship between financial agglomeration and regional economic growth using unit root test and cointegration test shows that there is a one-way long-term causal relationship between the former and the latter in the gap between financial agglomeration and regional economic growth.
