摘　　要：在数字技术与传统金融业融合的背景下,探究传统商业银行如何通过数字金融的发展来稳定信贷供给、推动金融高质量发展具有重要意义。本文基于2011—2021年200家商业银行的数据,实证考察数字金融发展对商业银行信贷供给的影响。研究发现,第一,整体上数字金融对商业银行的溢出效应大于挤出效应,进而显著地提升了商业银行信贷供给;第二,机制检验结果表明,数字金融通过技术溢出效应、经济溢出效应增加银行信贷供给,通过挤出效应降低银行信贷供给,具体包括夺取长尾客户、加剧市场竞争两条路径;第三,异质性分析显示,相较于地方性、中西部地区商业银行,数字金融对全国性、东部地区商业银行信贷供给的促进作用更为明显。In the context of the integration of digital technology and traditional finance,it is of great significance to explore how traditional commercial banks can stabilize credit supply and promote high-quality financial development through the advancement of digital finance.This paper,based on data from 200 commercial banks from 2011 to 2021,empirically examines the impact of digital finance development on the credit supply of commercial banks.The research finds that,first,overall,the spillover effect of digital finance on commercial banks is greater than the crowding-out effect,thereby significantly enhancing the credit supply of commercial banks;second,the results of the mechanism examination indicate that digital finance increases bank credit supply through technical and economic spillover effects while reducing it by capturing long-tail customers and intensifying market competition;third,the heterogeneity research results show that,compared to local and and mid-western banks,the promotion of digital finance on credit supply is more pronounced in national and eastern region banks.
