In　recent　years,　the　model　of　extensive　economic　development　at　the　expense　of　the　ecological　environment　has　been　gradually　abandoned　by　all　countries　in　the　world.　Green　economic　transformation　has　become　the　basic　consensus　of　societies　worldwide.　Capital　is　the　blood　of　enterprise　development.　The　rapid　development　of　the　green　economy　with　the　goal　of　supporting　the　green　transformation　of　the　economy　has　increased　the　financing　pressure　of　enterprises　caused　by　pollution.　This　paper　explores　the　internal　relationship　between　corporate　green　behavior　decision-making　and　corporate　green　financing　constraints　from　a　micro　perspective.　Based　on　the　data　of　China＇s　A-share　manufacturing　industry　from　2011　to　2019,　this　paper　examines　the　impact　of　corporate　ESG　performance　on　the　green　financing　constraints　for　it.　The　empirical　results　show　that　the　listed　companies　face　greater　green　financing　constraints　at　present.　The　overall　performance　of　corporate　ESG　is　conducive　to　easing　corporate　green　financing　constraints,　but　the　role　of　ESG　sub-performance　is　limited.　At　the　same　time,　there　are　regional　and　scale　differences　in　the　mitigation　effect　of　the　performance　of　corporate　ESGs　on　green　financing　constraints.　Finally,　this　paper　puts　forward　policy　suggestions　on　how　to　promote　the　alleviation　of　corporate　green　financing　constraints.　Namely:　(1)　enterprises　should　improve　themselves　by　improving　technological　innovation　and　utilization　rate　to　meet　the　requirements　of　green　development;　and　(2)　relevant　institutions　shall　formulate　appropriate　policies　and　conduct　reasonable　supervision　according　to　the　differentiated　requirements　of　enterprises　with　different　characteristics　in　different　regions.
