Based on the data of A-share listed companies from 2009 to 2024, this paper explores the impact of data resource information disclosure on corporate leverage manipulation. The results show that data resource information disclosure can significantly curb corporate leverage manipulation, and exerts a governance effect on off-balance-sheet liabilities and leverage manipulation in the form of nominal equity with substantive debt. Mechanism analysis reveals that relying on the information effect, resource effect and governance effect, data resource information disclosure substantially improves corporate information transparency, eases financing constraints and mitigates two types of agency problems, thereby suppressing firms' incentives for leverage manipulation. Heterogeneity analysis indicates that the inhibitory effect is more pronounced in non-state-owned enterprises, enterprises with high leverage ratios and high reliance on long-term debt, enterprises with high digital transformation, as well as firms located in regions with higher marketization and greater banking competition. The test of economic consequences finds that the restraining effect of data resource information disclosure on corporate leverage manipulation further reduces enterprises' financial risks. This research expands the literature on the economic consequences of data resource information disclosure from the perspective of governance functions, and provides important references for the prevention and governance of corporate leverage manipulation.
