摘要
本文选择2011—2018年中国城市经济发展数据,利用3SLS估计联立方程模型,探索数字普惠金融、银行业竞争和金融深化三者间的耦合关系,并深入分析数字普惠金融深层结构、银行类型和东中西部区域异质效应。结果发现,一是数字普惠金融与金融深化、银行业竞争与数字普惠金融两两间存在显著正向耦合关系,而银行业竞争与金融深化间存在显著负向耦合关系。二是数字普惠金融覆盖广度和使用深度二级指标与总指数效应表现一致,而数字支持起到明显的负向作用。三是数字普惠金融发展和金融深化有利于国有大行和股份制商业银行市场份额提升,而前期可能相对不利于农村商业银行,且国有大行集中度提升对数字普惠发展和金融深化有显著正向作用。四是东部、中部区域银行业竞争、金融深化和数字普惠金融的关系表现呈一致性,而西部区域不同。如西部城市数字普惠金融发展降低了银行业市场竞争,而东部、中部区域则相反。五是数字普惠金融的正向作用较为确定,而银行业竞争、金融深化的作用因境而异。
In order to explore the coupling relationship among digital Inclusive Finance,banking competition and financial deepening,this paper selects the economic development data of China’s prefecture level cities from 2011to 2018,uses the 3SLS estimation simultaneous equation model,and examines the deep structure of digital Inclusive Finance,bank types and regional heterogeneity in the East,central and western regions.The results show that,first,there is a significant positive coupling relationship between digital Inclusive Finance and financial deepening,banking competition and digital Inclusive Finance,while there is a significant negative coupling relationship between banking competition and financial deepening.Second,the coverage and use depth of digital inclusive finance are consistent with the overall index effect,while digital support plays a significant negative role.Third,the development and financial deepening of digital inclusive finance are conducive to the increase of market share of large state-owned banks and joint-stock commercial banks,but not conducive to rural commercial banks.Moreover,the increase of concentration of large state-owned banks has a significant positive effect on the development and financial deepening of digital Inclusive Finance.Fourth,the relationship between banking competition,financial deepening and digital Inclusive Finance in the eastern and central regions is consistent,while the western regions are different.For example,the development of digital Inclusive Finance in western cities has reduced the competition in the banking market,while the eastern and central regions have the opposite.Fifth,the positive role of digital Inclusive Finance is relatively certain,while the role of banking competition and financial deepening varies from country to country.
