With　growing　concern　about　social　impacts　and　environmental　protection,　sustainable　supply　chain　management　has　become　a　focus　of　interest　for　business　practitioners　and　academics.　This　study　examines　the　driving　forces　of　sustainable　supply　chain　management　practices.　Drowning　on　institutional　theory　and　the　resource-based　view,　this　study　empirically　examines　the　driving　effects　of　institutional　pressures　(in　terms　of　governance　pressure,　customer　pressure,　and　competitive　pressure)　and　internal　sustainability　capabilities　(in　terms　of　top　management　leadership　and　technical　capability)　and　their　interactions　on　sustainable　supply　chain　management　practices.　Based　on　empirical　analysis　of　data　from　172　Chinese　firms,　the　findings　reveal　that　institutional　pressures　and　sustainability　capabilities　simultaneously　and　jointly　motivate　the　implementation　of　sustainable　supply　chain　management　practices.　Interestingly,　the　interactions　of　technical　capabilities　with　governance　pressures　and　customer　pressures　significantly　and　negatively　influence　sustainable　supply　chain　management　practice　adoption,　while　the　interactions　of　top　management　leadership　with　competitive　pressures　positively　affect　the　pursuit　of　sustainable　supply　chain　management　practices.　©　2021　Institution　of　Chemical　Engineers
