While　identification　of　the　drivers　of　eco-innovation　in　firms　is　a　popular　topic　in　the　literature,　many　questions　about　these　drivers　in　developing　countries　remain　unanswered.　The　present　study　aims　to　determine　empirically　the　primary　factors　that　influence　adoption　of　eco-innovation　in　Chinese　firms.　To　achieve　this,　a　conceptual　model　is　developed　and　tested　on　a　large　database　of　firms　from　various　industries,　using　hierarchical　regression　analysis.　The　study　reveals　that　eco-innovation　is　triggered　by　a　mixture　of　internal　and　external　drivers.　However,　in　China,　the　external　pressures　from　environmental　regulations,　customers＇　green　demands,　and　competitors　affect　eco-innovation　partially　through　internal　drivers.　The　analysis　further　shows　that　firms＇　integrative　capability　-　the　ability　to　adopt　appropriate　eco-innovative　responses　by　combining　internal　and　external　capabilities　-　partially　mediates　the　relationship　between　drivers　and　eco-innovation　performance.　Moreover,　firms　that　have　more　efficient　external　networks　tend　to　conduct　more　eco-innovative　activities.　This　study　contributes　to　a　more　detailed　understanding　of　the　factors　that　initiate　and　boost　eco-innovation.　©　2014　Elsevier　Ltd.　All　rights　reserved.
