Environmental　corporate　social　responsibility　is　important　for　firms　to　achieve　both　economic　benefits　and　the　sustainable　development　of　firms　and　the　environment,　which　are　of　great　concern　to　theorists　and　practitioners.　However,　the　relationship　between　environmental　corporate　social　responsibility　and　green　innovation　performance　is　still　unclear.　To　address　the　research　gap,　we　propose　a　research　model　that　incorporates　the　mediating　effect　of　shared　vision　capability,　and　the　moderating　effect　of　resource　slack,　to　investigate　whether　and　when　environmental　corporate　social　responsibility　affects　green　innovation　performance.　Data　were　obtained　from　351　respondents　of　Chinese　firms　through　a　questionnaire.　The　results　confirmed　that　environmental　corporate　social　responsibility　is　positively　associated　with　green　innovation　performance.　The　results　also　confirmed　that　shared　vision　capability　mediated　the　environmental　corporate　social　responsibility-green　innovation　performance　link.　Resource　slack　statistically　significantly　moderated　the　relationship　between　environmental　corporate　social　responsibility　and　green　innovation　performance.　These　findings　offer　novel　insight　for　managers　when　formulating　management　policies　about　environmental　corporate　social　responsibility,　shared　vision　capability,　and　green　innovation　performance,　which　can　help　enterprises　to　achieve　the　goal　of　sustainable　development　and　promote　environmental　friendliness　in　society　at　large.
