摘　　要：从“收入”和“成本”双重角度将数字化纳入到银行风险偏好的理论框架,并在此基础上采用中国银行业的面板数据进行实证检验.结果发现:银行数字化显著提升了自身的风险偏好.机制检验表明,银行数字化通过提高收入端的风控效应和降低成本端的管理成本,进而提高自身的风险偏好.异质性分析发现,数字化对较小规模、资本充足率较低及处于金融业发展薄弱地区的银行风险偏好的影响更为显著.贷款配置方面,数字化驱动风险偏好提升会进一步对信用贷款和公司贷款具有显著的促进作用.进一步研究还发现,数字化有利于驱动银行“回归本源”更好地服务实体经济,同时对内部银行绩效也产生了较为积极的影响,不仅降低了破产风险还提高了收益.本文有助于深层次理解银行数字化的微观经济后果,从而为制定提高金融服务实体经济质效的经济政策提供经验支撑.This paper incorporates digitalization into the theoretical framework of bank risk preference from both the perspectives of income and cost.Based on this framework,it uses panel data from the Chinese banking industry for empirical testing.The results show that digitalization significantly enhances banks'risk preference.Mechanism testing suggests that digitalization improves risk preference by increasing the risk control effect on the income side and reducing management costs on the cost side.Heterogeneity analysis finds that the effect of digitization on risk preference is more significant for banks that are smaller,have lower capital adequacy ratios and are located in areas with weak financial sector development.In terms of loan allocation,digitalization significantly promotes credit loans and corporate loans,providing indirect evidence for the increase in risk preference.Further research also finds that digitalization helps drive banks to return to their roots and better serve the real economy,while also having a more positive impact on internal bank performance,reducing bankruptcy risks and increasing profits.This paper contributes to a deeper understanding of the micro-economic consequences of bank digitalization,thereby providing empirical support for economic policies designed to improve the quality and efficiency of financial services to the real economy.
