We　investigate　the　effect　of　corporate　digitalization　capabilities　on　green　innovation　among　Chinese-listed　firms.　Using　a　panel　dataset　of　2908　companies　from　2011　to　2020,　we　use　textual　analysis　and　entropy　weighting　on　corporate　annual　reports　to　construct　a　yearly　corporate　digitalization　index.　Our　findings　show　that　corporate　digitalization　promotes　green　innovation,　as　evidenced　by　patent　applications　and　grants.　This　relationship　is　stronger　for　firms　with　fewer　financial　constraints　and　in　provinces　with　strong　intellectual　property　protection.　We　also　find　the　national　digital　policy　of　the　＂Internet　Plus＂　strategy　has　a　stronger　positive　effect　on　corporate　green　innovation　for　corporations　with　a　higher　degree　of　digitalization.　Our　results　are　robust　to　various　alternative　measures,　econometric　models,　and　different　samples.
