Sustainable　social　responsibility　(SSR)　toward　multiple　stakeholders　is　proclaimed　as　an　obligation　of　firms　rather　than　a　voluntary　deed.　Keeping　in　view　the　stipulation　of　sustainability,　this　paper　examines　the　influence　of　SSR　on　sustainable　competitive　position　(SCP)　and　firm　performance　(FP)　in　the　context　of　307　Chinese　small-　and　medium-sized　enterprises.　The　results　indicate　a　significant　influence　of　aggregated　and　segregated　SSR　on　SCP　and　FP.　With　the　exception　of　SSR　toward　owners,　the　dimensions　of　SSR　toward　employees,　the　environment,　the　community,　suppliers,　and　customers　exhibit　a　significant　positive　influence　on　SCP　and　FP.　Simultaneously,　the　results　show　that　SCP　has　a　mediating　role　in　the　relationship　between　SSR　and　FP.　The　findings　of　the　study　inculcate　the　managers　to　stretch　substantial　consideration　to　the　interests　of　multiple　stakeholders　rather　than　owners　only.　Based　on　the　evaluation,　theoretical　and　practical　implications　are　presented　for　managers,　owners,　and　local　governments.
