Timely disclosure of accounting information is helpful to promote investor protection and maintain the stable operation of the market. Taking A-share listed companies from 2011 to 2021 as research samples, this paper discusses the impact of the development of digital finance on the delay on scheduled annual report disclosure. It finds that the development of digital finance can reduce delays on scheduled annual report disclosure. The mechanism test results show that digital finance exerts a “supervision effect” by restraining executive violations and a “financial support effect” by easing corporate financing constraints, thereby reducing delays on scheduled annual report disclosure. Further research shows that digital finance “complements” corporate culture, external supervision “drives” digital financial governance function, and digital finance plays a supervisory role in audit compromise behavior, that is, in enterprises with low level of business culture, low level of integrity culture, high level of CSRC supervision, high level of financial market supervision, and high level of customer importance, digital finance has a more significant inhibitory effect on the delay on scheduled annual report disclosure.
