Abstract This paper takes the opening of public data platforms across diverse prefecture-level cities as a quasi-natural experiment to assess the influence of public data access on the within-firm income gap with a multi-period difference-in-differences model based on the data of A-share listed companies in China over the period 2009~2022. The research finds that access to public data significantly widens the within-firm income gap. Mechanism test shows that public data access expands within-firm income gap by enhancing managerial ability and risk compensation to increase the management salary. Further heterogeneous analyses suggest that the role of public data access in widening within-firm income gap is more pronounced in enterprises which are non-state-owned, with management teams having a digital background and those in capital- and technology-intensive industries. However, skill enhancement can bolster the bargaining power of general employees, thereby effectively mitigating the negative impact of public data access on corporate income distribution.
