摘　　要：基于区域差异化发展战略,利用北京大学数字普惠金融指数与泰尔指数构建面板分位数模型,探索长江经济带如何科学发展数字普惠金融体系收敛城乡收入差距,研究显示:长江经济带数字普惠金融对泰尔指数的收敛效应主要来源于金融覆盖广度,金融使用深度缺乏显著性,数字化程度甚至扩大泰尔指数;数字普惠金融三大层次在长江经济带上、中、下游对泰尔指数具有明显异质性影响;分位数回归表明,总体上长江经济带数字普惠金融对泰尔指数大于20%分位省份发挥收敛效应,覆盖广度使拐点提升至30%以上,使用深度使拐点恢复至20%,但不利于70%以上分位省份发挥收敛功能,数字化程度则显著扩大40%以上分位省份收入差距。因此,数字普惠金融建设应按地区实际进行动态调整,提升农村居民金融素养,创新农村金融产品与服务供给。Constructing a panel quantile model based on regional differentiated development strategies using Peking University Digital Inclusive Finance Index and Theil Index to explore how the Yangtze River Economic Zone can scientifically develop a digital inclusive finance system to converge the urban-rural income gap.The study shows that the convergence effect of digital inclusive finance in the Yangtze River Economic Zone on the Theil Index stems mainly from the breadth of financial coverage,the lack of significance of the depth of financial use and the degree of digitization even expanding the Thayer Index;the three major levels of digital inclusive finance have significant heterogeneous effects on the Theil Index in the upper,middle and lower reaches of the Yangtze River Economic Belt;quantile regressions show that overall digital inclusive finance in the Yangtze River Economic Zone exerts a convergence effect on provinces in the greater than 20%quantile of the Theil Index,the breadth of coverage raises the inflection point to more than 30%,the depth of use restores the inflection point to 20 percent,but is not conducive to the convergence function in provinces in the greater than 70 percent quantile,and the degree of digitization significantly widens the income gap in provinces in the greater than 40 percent quantile.Therefore,the construction of digital financial inclusion should be dynamically adjusted according to regional realities,to improve the financial literacy of rural residents,and to innovate the supply of rural financial products and services.
