The　aim　of　this　study　is　to　investigate　the　decision-making　mechanism　of　reusable　mobile　phone　trading　behaviors　by　using　the　extended　theory　of　planned　behavior.　In　this　study,　based　on　the　survey　data　of　964　residents　in　Beijing,　China　and　structural　equation　modeling　method,　the　main　factors　that　affect　consumers＇　reusable　mobile　phone　trading　behavior　and　their　degree　of　influence　were　analyzed,　followed　by　discussion　on　decision-making　mechanisms.　The　findings　show　that　consumers＇　behavioral　selection　has　been　significantly　related　to　four　intrinsic　subjective　factors　and　fifteen　external　objective　factors,　and　the　combined　effect　of　the　latter　ones　is　nearly　triple　of　that　of　the　former　ones.　Moreover,　the　observed　variables　of　environmental　awareness,　information　leakage　sensitivity,　trading　convenience　and　consumer　trading　returns　are　the　four　most　significant　factors.　The　impact　of　active　trading　behavior　is　not　significant.　However,　this　may　be　because　that　there　were　no　great　trading　rewards,　lack　of　trading　awareness　and　regulations.　Finally,　the　study　put　forward　relevant　policy　recommendations　for　improving　the　comprehensive　management　of　recycling　reusable　mobile　phones,　and　provides　a　theoretical　reference　for　improving　the　recycling　rate　of　reusable　mobile　phones.
