摘要:根据长三角城市群26个城市2005,2010,2018年面板数据,采用因子分析评价城市历年金融集聚程度,以金融开放指标对各市进行基于特征提取的K均值动态聚类划分,实证分析了金融开放对长三角各城市金融集聚的影响.结果发现,总体上金融对外开放对城市金融集聚程度有显著正向影响,但这种促进作用主要集中于自身金融开放水平较高的发达城市,在开放层次低的欠发达城市中表现为负向抑制作用,从而显示出地区间明显的异质性.

Abstract: According to the panel data of 26 cities in the Yangtze River Delta urban agglomeration from 2005 to 2018,this paper uses factor analysis to evaluate the degree of financial agglomeration of cities over the years,and uses the financial openness index to conduct the K-means dynamic clustering division based on feature extraction,and empirically analyzes the impact of financial openness on the financial agglomeration of cities in the Yangtze River Delta.The results show that,on the whole,financial opening up has a significant positive impact on the degree of urban financial agglomeration,but this promoting effect is mainly concentrated in the developed cities with higher level of financial opening up,and shows a negative inhibitory effect in the less developed cities with lower level of opening up,which shows obvious heterogeneity among regions.

Key words: financial openness, financial agglomeration, factor analysis, feature extraction, cluster analysis
