Haze　pollution　has　become　one　of　the　most　serious　environmental　problems　in　China,　especially　in　Beijing-Tianjin-Hebei　region.　Chinese　government　has　issued　a　haze　control　policy　in　2013,　which　aims　to　alleviate　haze　pollution　through　reducing　emission　of　air　pollutants.　However,　there　is　a　doubt　whether　the　haze　concentration　target　can　be　achieved　through　implementation　of　the　air　pollutants　emission　reduction　plan.　This　paper　focused　upon　the　numerical　relationship　between　haze　concentration　and　air　pollutants　emission　based　on　data　analysis　approach　in　the　Beijing-Tianjin-Hebei　region.　The　haze　control　policy　in　the　Beijing-Tianjin-Hebei　region　should　shift　from　concentration　target　to　emission　control　target.　Tianjin　and　Hebei　should　reduce　much　more　air　pollutants　emission.　Beijing　should　consider　a　more　reasonable　concentration　target　and　emission　control　plan　for　joint-regional　efforts.
