【摘要】 基于2011—2018年城市面板数据对金融业全要素生产率进行测算,以及运用DID和工具变量法检验数字普惠金融对金融业全要素生产率的影响,研究发现,第一,数字普惠金融的发展可以显著降低金融业全要素生产率,这一抑制效应还表现在对技术效率和科技进步效率的影响上。数字普惠金融的覆盖广度仅对金融业全要素生产率产生抑制效应,使用深度仅对金融业全要素生产率和技术效率产生抑制效应,而数字支持服务程度则对金融业全要素生产率、技术效率和科技进步率均产生抑制效应。第二,数字普惠金融抑制金融业全要素生产率的机制可以通过"资源竞争假说"解释。第三,城市行政级别不同,数字普惠金融与金融业全要素生产率之间的作用关系相同、作用机制不同。因此,需针对金融机构的特点实施差异化政策,推进金融机构数字化转型,提高金融业数字技术水平。更多还原

【Abstract】 Based on the urban panel data from 2011 to 2018, this paper calculates the total factor productivity of the financial industry. It also applies DID and instrumental variable method to test the impact of digital inclusive finance on the total factor productivity of the financial industry. The findings show that, firstly, the development of digital inclusive finance can significantly reduce the total factor productivity of the financial industry, and that this inhibitory effect is also reflected on the impact on technical efficiency and scientific and technological progress efficiency. The coverage of digital inclusive finance only has a restraining effect on the total factor productivity of the financial industry. The depth of the usage only has an inhibition effect on the total factor productivity of the financial industry and the technical efficiency, while the degree of digital support service has inhibitory effects on all the three, i.e., the TFP of the financial industry, the technical efficiency and the scientific and technological progress efficiency. Secondly, the mechanism that digital inclusive finance inhibits the total factor productivity of financial industry can be explained by the “resource competition hypothesis”. Thirdly, if the administrative levels of the cities are different, the interactive relationship between digital inclusive finance and total factor productivity of financial industry will be the same,but the interactive mechanism will be different. Therefore, it is necessary to carry out the different policies against the characteristics of the financial institutions, promote the digital transformation of the financial institutions, and improve the digital technological level of the financial sector.更多还原
