The　question　of　how　to　improve　green　management　(GM)　is　very　important　for　the　sustainable　development　of　the　world.　While　this　topic　has　been　extensively　investigated　at　the　single　firm　level　in　the　developed　countries,　it　was　insufficiently　examined　in　the　context　of　interfirm　alliances,　especially　in　developing　countries　like　China.　The　current　study　examines　how　different　sources　of　resources　(internal　resource　accumulation　and　external　resource　acquisition)　affect　the　level　of　alliance　green　management　(AGM).　In　addition,　entrepreneurial　orientation　(EO)　that　represents　the　willingness　of　firms　to　adopt　new　practices　has　moderating　effects　on　the　above　relationships.　Moreover,　the　effect　of　AGM　on　alliance　performance　is　also　examined.　We　collected　multisource　data　from　164　alliance　firms　in　Chinese　manufacturing　industry.　The　results　generally　support　the　proposed　hypotheses.　This　study　contributes　to　both　GM　and　alliance　research　by　identifying　the　internal　and　external　resource　factors　that　influence　firms　from　emerging　economies　to　practice　GM　in　their　alliance　operations.　(C)　2016　Elsevier　Ltd.　All　rights　reserved.
