In　view　of　recycling　and　reuse　of　used　clothing,　after　analysis　of　the　recycling　mode　of　used　clothing,　established　the　economic　model　of　the　processors　recycling　independently　(PRI)　and　the　third　party　recycling　(TPR)　based　on　the　consumer　recycling　awareness,　and　made　the　comparative　analysis　of　two　models.　The　results　show　that　the　two　models　have　the　optimal　solution,　recycling　quantity　decides　the　optimal　profit　scale　of　two　models,　the　price　of　the　used　clothes　that　the　third　party　enterprise　pays　and　the　amount　of　the　back　box　that　the　enterprise　established　decide　two　models　of　the　pros　and　cons.　The　scale　economy　effect　of　enterprise　recovery　by　itself　is　more　obvious,　externality　and　rent-seeking　profit　existence　cause　the　model　dividing　line　shift.　Developing　the　value　evaluation　criteria　for　used　clothing　and　improving　the　recycling　awareness　of　resident　is　the　key　point　to　promote　the　popularization　of　the　used　clothing　models　in　the　country.　©　2016,　Editorial　Board　of　Journal　of　Systems　Engineering　Society　of　China.　All　right　reserved.
