Intelligent　transformation　plays　a　crucial　role　in　advancing　sustainable　development　in　manufacturing　while　also　enhancing　the　information　environment.　This　study　examines　the　role　of　intelligent　transformation　in　China＇s　manufacturing　sector,　spanning　theoretical　and　empirical　dimensions　and　being　anchored　in　the　context　of　capital　market　information　efficiency.　The　theoretical　framework　highlights　how　intelligent　transformation　mitigates　information　asymmetry,　aligning　a　firm＇s　valuation　with　its　intrinsic　value,　thereby　elevating　the　information　efficiency　of　capital　markets.　Leveraging　annual　reports　from　China＇s　A-share　manufacturing　firms,　this　study　employs　textual　analysis　to　construct　indicators　assessing　the　extent　of　intelligent　transformation　across　these　entities.　The　empirical　findings　of　this　study　harmonize　with　the　theoretical　constructs.　Notably,　intelligent　transformation　emerges　as　a　pivotal　driver　in　enhancing　information　efficiency　in　capital　markets,　substantiated　by　a　negative　correlation　between　intelligent　transformation　and　stock　price　synchronicity　within　the　manufacturing　domain.　This　correlation　withstands　a　battery　of　robustness　tests　and　endogeneity　treatment.　The　mechanism　driving　this　transformative　impact　lies　in　intelligent　transformation＇s　ability　to　enhance　productivity　and　magnify　market　attention,　thereby　positively　influencing　capital　market　information　efficiency.　The　insights　not　only　provide　empirical　support　but　also　offer　practical　guidance　for　improving　real-world　company　operations　and　developing　high-quality　capital　markets.
