Enterprise　for　improving　corthe　s　face　fierce　market　competition　and　changing　business　environment　as　a　result　of　globalization　and　technological　advancements.　Digital　transformation　and　green　development　have　emerged　as　critical　strategies　degree　of　synergistic　transformation　of　digitalization　and　greening　by　using　the　coupled　coordination　model.　Moreover,　we　explore　the　influence　of　synergistic　transformation　oporate　competitiveness　and　achieve　sustainable　development.　This　study　delves　into　the　panel　data　of　Chinese　A-share　listed　companies　in　Shanghai　and　Shenzhen　from　2007　to　2022.　We　construct　an　index　of　f　digitalization　and　greening　(referred　to　as　＂dual　synergistic＂　transformation)　on　the　total　factor　productivity　(referred　to　as　TFP)　of　enterprises　by　using　the　fixed　effect　model.　Results　showed　a　significant　positive　relationship　between　the　degree　of　＂dual　synergistic＂　transformation　and　enterprise　TFP.　The　regression　results　remain　robust　after　a　series　of　robustness　and　endogeneity　discussions.　Government　subsidies　can　effectively　play　a　moderating　role,　which　strengthens　the　influence　of　＂dual-chemistry　synergy＂　transformation　on　firms＇　TFP.　Furthermore,　we　analyze　the　heterogeneity　of　the　study　sample　and　find　that　the　positive　influence　of　＂dual　synergistic＂　transformation　on　firms＇　TFP　is　more　significant　in　non-state-owned　enterprises,　heavily　polluting　industries,　and　non-high-tech　and　capital-intensive　firms.　This　positive　effect　is　weaker　for　SOEs,　non-polluting　industries,　high-tech,　and　labor-intensive　and　technology-intensive　firms.　In　addition,　our　study　reveals　that　R&D　investment　and　financing　constraints　play　critical　roles　in　the　＂dual　synergistic＂　transformation.　Therefore,　policy　subsidies　should　be　further　increased,　and　the　financing　environment　should　be　optimized　to　promote　the　productivity　improvement　of　enterprises　in　the　digital　and　green　transformation,　while　strengthening　the　support　of　green　social　work　for　corporate　social　transformation,　to　help　enterprises　achieve　environmental　benefits　while　also　addressing　social　responsibilities　and　community　development.
