The　social　and　economic　development　in　China　has　not　only　made　a　series　of　great　achievements　but　also　suffered　from　increasingly　serious　air　pollution.　It　is　of　great　significance　to　explore　the　co-governance　mechanism　of　air　pollution　in　order　to　promote　high-quality　development　and　the　construction　of　＂beautiful　China.＂　Based　on　an　analysis　using　the　concept　of　co-governance,　this　paper　reviews　the　research　from　four　aspects:　the　multi-object　relationships,　multi-agent　framework,　and　the　co-governance　technical　tools　and　policy　tools.　The　results　show　that　the　current　research　has　many　deficiencies:　a　lack　of　research　on　the　size,　direction,　and　driving　factors　of　the　correlation　of　objects;　the　construction　of　the　multi-agent　framework　focused　only　on　concepts　and　lacking　the　design　of　core　mechanisms;　evaluating　only　the　effect　of　tools　but　ignoring　the　optimal　combination　of　governance　tools,　and　paying　attention　only　to　the　traditional　pollutants　and　disregarding　the　latest　air　pollution.　Accordingly,　this　paper　finds　that　the　research　should　be　expanded　from　four　aspects,　which　include　taking　into　account　the　co-governance　of　new　air　pollution,　clarifying　the　relationship　between　the　various　types　of　air　pollutants　and　the　driving　factors,　building　a　multi-disciplinary　research　framework　for　co-governance,　and　optimizing　the　combination　of　governance　policies　and　technical　tools　in　order　to　realize　high-quality　development　of　China.
