Abstract: Firstly, this paper analyzes the influence mechanism of internet finance on traditional commercial banks from the perspectives of bank assets, liabilities and payment and settlement. Then, based on the data of 79 commercial banks in China from 2010 to 2018, a variety of estimation methods are used to conduct empirical analysis. The results show that internet finance has obvious negative impact on the performance of commercial banks in China. The financial development level and other factors also produce important impacts from different aspects. The test results of impact mechanism confirm that the development of internet finance has brought significant negative impact on banks' net interest income and noninterest income, which further influences bank's performance. The heterogeneity tests show that the impact of internet finance on agricultural commercial banks' and city commercial banks' performance is greater than that on stateowned large and mediumsized banks. Banks located in the eastern regions, carrying out crossregional operations and with higher innovative abilities can better respond to the impact of internet finance. In the new financial ecology, the deepening integration of information technology, and accelerating transformation and innovation of Fintech are the important strategic approaches of further sustainable development for traditional commercial banks.

摘要： 本文首先从银行资产、负债以及支付结算等方面分析了互联网金融对传统商业银行的影响机理，然后选取中国2010—2018年79家商业银行数据，通过建立多元面板回归模型，对互联网金融发展与银行绩效之间的具体关联进行实证分析。结果表明：互联网金融对我国商业银行绩效具有明显的负面冲击作用，货币政策、金融发展程度等因素也对银行绩效有重要影响。影响机理的检验结果证实：互联网金融发展给银行的净利息和非利息收入都造成了显著的负面冲击，进而影响银行绩效。异质性检验结果表明：互联网金融对农商行、城商行等小型银行绩效的影响要大于全国性的大中型银行。位于东部地区、开展跨区域经营、创新能力强的银行能更好地应对来自互联网金融的冲击。在新的金融生态下，深度融合信息技术，积极向金融科技转型创新是传统商业银行可持续发展的重要战略途径。
