This paper examines the relationship between population aging and corporate digital transformation from the perspective of demographic changes. Generally, the findings indicate that population aging notably contributes to corporate digital transformation, mainly through increasing labor costs, including expected and actual labor costs. Further analysis suggests that the above effects are significantly weakened in samples of firms with lower levels of regional intellectual property protection, higher corporate financial constraints, and shorter-sighted managerial decision-making. Moreover, the economic consequences test implies aforementioned favorable effects can enhance corporate total factor productivity.
