摘　　要：本文手工搜集了2007—2019年29家上市银行的金融科技(Fintech)投入数据,借助DEAMalmquist模型测度全要素生产率,对银行生产率悖论进行了验证,并从银行盈利能力视角解释这一现象。研究发现,现阶段商业银行金融科技投入对生产率的正向溢出并不显著,一定程度存在生产率悖论。金融科技投入通过降低成本收入比提升了上市银行总体盈利水平,但对各类银行的资产利用效率均影响甚微,其“降本”作用优于“增效”,生产率效应渠道存在阻滞。商业银行在提高金融科技投入的同时增进内部要素的互补性,贯通生产率效应渠道,是跨越金融科技投入生产率悖论的关键。本文研究结论为更好地配置金融科技资源来增强银行服务实体经济能力提供了政策启示。This paper manually collected Fintech input data of 29 listed Banks from 2007 to 2019,measured total factor productivity by DEA-Malmquist model,verified the paradox of bank productivity,and explained this phenomenon from the perspective of bank profitability.It is found that the positive spillover of fintech investment on productivity in commercial Banks is not significant at present,and there is a productivity paradox to some extent.Fintech investment improves the overall profitability of listed Banks by reducing the cost-income ratio,but it has little impact on the asset utilization efficiency of all kinds of Banks.Its“cost reduction”effect is better than“efficiency increase”,and the channel of productivity effect is blocked.It is the key for commercial Banks to overcome the paradox of fintech input productivity by increasing fintech input and the complementarity of internal factors and connecting the channels of productivity overflow.The conclusions provide policy enlightenment for better allocation of fintech resources to enhance the ability of Banks to serve the real economy.
