In　an　increasingly　globalised　business　environment,　optimising　manufacturing　and　market　strategies　has　become　crucial　for　multinational　firms　(MNFs)　seeking　competitive　advantages　over　local　firms.　Of　particular　significance　is　understanding　how　intervention　in　emerging　economies　impacts　cross-border　supply　chains.　Therefore,　this　study　examines　a　cross-border　supply　chain　featuring　an　MNF　from　an　industrialised　nation　and　a　rival　from　an　emerging　economy.　Under　different　government　interventions,　the　analysis　encompasses　two　manufacturing　strategies–offshore　manufacturing　(OFM)　and　onshore　manufacturing　(ONM)–across　four　distinct　marketing　structures.　Key　findings　reveal　that:　(1)　In　the　absence　of　government　intervention:　(i)　under　ONM,　newly　introduced　metrics　of　cost　pressure　and　competition　pressure　effectively　determine　market　access　criteria　for　both　the　MNF　and　its　rival;　(ii)　a　clear　threshold　emerges　for　manufacturing　strategy　selection,　with　the　MNF　opting　for　ONM　below　this　threshold　and　OFM　above　it.　(2)　Government　interventions　yield　varying　effects:　(i)　while　government　subsidies　(GS)　do　not　influence　the　MNF＇s　manufacturing　strategy　choice,　it　creates　two　distinct　scenarios　regarding　the　rival＇s　revenue　sources;　(ii)　technical　trade　barriers　(TB)　implementation　increases　the　likelihood　of　OFM　adoption　by　the　MNF,　and　their　combined　effect　may　compel　the　MNF　to　withdraw　from　the　emerging　market　under　certain　conditions.　©　2024　Informa　UK　Limited,　trading　as　Taylor　&　Francis　Group.
