Green　finance　is　an　important　aspect　of　the　modern　Chinese　financial　system　with　high-quality　development,　but　best　practices　in　promoting　its　rapid　development　have　yet　to　be　robustly　explored.　This　study　first　analyzes　the　difficulty　in　the　current　development　of　green　finance　in　China　and　its　causes,　and　then　analyzes　the　impact　mechanism　of　new　governance　measures　based　on　the　results　of　an　enterprise　environmental　credit　evaluation　conducted　on　green　finance.　Using　the　panel　data　of　280　cities　from　2010　to　2021,　we　take　43　credit　construction　demonstration　cities　that　have　been　approved　by　the　state　as　quasinatural　experiments　for　the　construction　of　a　multiple-timepoint　double-difference　model.　The　study　finds　that　the　environmental　credit　governance,　as　represented　by　a　credit　construction　demonstration　city,　significantly　promotes　the　local　green　finance　level,　and　the　mechanism　test　confirms　that　this　positive　effect　was　achieved　by　accelerating　the　data　factorization.　In　addition,　we　find　that　the　effect　of　environmental　credit　governance　is　more　obvious　in　cities　with　higher　administrative　levels　and　more　advantageous　geographical　locations.　We　provide　further　micro　theoretical　support　for　China＇s　goal　of　achieving　the　two　major　political　tasks　of　ecological　environmental　protection　and　social　credit　construction,　and　provide　new　inspiration　for　optimizing　environmental　governance　strategies.
