城市群战略对区域金融效率的影响——基于双重差分法的研究

Effects of Urban Agglomeration Strategy on Regional Financial Efficiency:Based on Double Difference Method

利用1997-2015年分省数据,基于多阶段DEA方法测度区域金融效率水平,进而构建双重差分模型实证研究了城市群战略对区域金融效率的影响。研究结果表明:城市群战略显著促进了区域金融效率的提高,该结论在进行稳健性检验后仍具有说服力。城市群对区域金融效率的推动作用在不同地区间表现出差异性,相比较于经济发达的东部沿海地区,经济发展相对落后的西部内陆地区金融效率获得了更大幅度的提升。可见城市群不仅能够提高区域金融效率,还有助于缩小区域金融发展不平衡,促进区域金融协调发展。

Based on the 1997-2015 provincial data and the measurement of regional financial efficiency via multi-stage DEA method,this paper constructs a double difference model and studies empirically the effects of urban agglomeration strategy on regional financial efficiency. The results show that the urban agglomeration strategy has promoted the regional financial efficiency,and this conclusion is persuasive after a robustness test. The promoting effect of urban agglomeration on regional financial efficiency is different in different regions,and compared with the economically developed eastern coastal areas,the financial efficiency in western inland areas with relatively backward economic development has been promoted more greatly. It can be seen that the urban agglomeration can not only improve the regional financial efficiency,but also help to reduce the imbalance of regional financial development and promote the coordinated development of regional finance.
