Corporate　digital　transformation,　primarily　driven　by　data　and　leveraging　digital　technologies　and　mathematical　algorithms　such　as　Internet+,　big　data,　cloud　computing,　artificial　intelligence,　and　blockchain,　is　a　crucial　enabler　of　sustainable　development.　This　transformation　integrates　various　aspects　of　corporate　production　and　operations,　enhancing　the　level　of　digital　operations　and　ultimately　contributing　to　high-quality　and　sustainable　development.　This　paper,　based　on　data　from　listed　companies　in　China＇s　A-shares　from　2007　to　2021,　theoretically　articulates　the　intrinsic　mechanism　between　corporate　digital　transformation　and　corporate　governance　level,　with　a　focus　on　sustainability.　It　empirically　finds　that　a　higher　degree　of　digital　transformation　correlates　with　an　improved　level　of　corporate　governance,　fostering　sustainable　practices.　Further　investigation　reveals　that　digital　transformation　elevates　corporate　governance　by　enhancing　innovation　capabilities,　reducing　information　asymmetry,　and　promoting　sustainable　strategies.　This　paper　provides　policy　insights　for　promoting　corporate　digital　transformation　as　a　means　to　achieve　sustainability　goals　and　optimizing　management＇s　corporate　governance　level　for　long-term　sustainable　success.
