In　recent　years,　China　has　gradually　become　one　of　the　countries　with　the　largest　levels　of　foreign　direct　investment　(FDI).　FDI　has　played　a　significant　role　in　promoting　Chinese　economic　development,　and　the　FDI　technology　spillover　effect　is　one　of　the　core　forces　driving　China　towards　reaching　new　growth　milestones.　Therefore,　due　to　the　country＇s　interest　in　development,　there　is　competition　for　FDI　throughout　China.　However,　the　existing　imperfect　environmental　protection　system　cannot　prevent　FDI　from　flowing　into　China＇s　highly　polluting　and　resource-intensive　industrial　chain,　possibly　causing　serious　environmental　problems.　Therefore,　the　topic　of　properly　introducing　foreign　capital　to　promote　development　and　effectively　end　China＇s　current　environmental　pollution　crisis　has　become　a　research　focus.　To　explore　FDI＇s　impact　on　China＇s　economic　growth,　technological　innovation,　and　environmental　pollution,　we　use　Chinese　provincial　panel　data　for　2004-2016　to　construct　a　dynamic　panel　simultaneous-equation　model.　Considering　the　interrelationships　between　the　equations,　we　construct　economic　models　of　economic　growth,　technological　innovation,　and　pollution　emissions,　and　incorporate　them　into　the　same　research　system　for　generalized　method　of　moments　(GMM)　estimation.　Our　results　show　that　FDI　has　a　significant　and　positive　direct　impact　on　China＇s　economic　growth　and　technological　innovation,　and　can　furthermore　have　a　significant　pull　effect　on　the　domestic　economy　through　the　backward　spillover　channel.　At　the　same　time,　FDI　has　a　direct　and　significant　impact　on　the　increase　in　regional　waste-water　discharge,　while　exhibiting　a　pollution　halo　effect　on　the　emission　of　sulfur　dioxide　(SO2)　and　chemical　oxygen　demand　(COD)　emissions　directly.　In　addition,　we　observe　＂benign　feedback　mechanism＂　between　technological　innovation　output　and　these　three　types　of　pollution,　namely　SO2　emission,　COD　emissions,　and　ammonia　and　nitrogen　discharge.
