To reduce air emissions of polycyclic aromatic hydrocarbons （ PAHs）, which impose health threats and risk of cancer to humans, it is necessary to control the behavior of production and emission of enterprise, and by source apportionment, it is possible to make sure the PAHs emissions type of discharge contamination enterprises. By applying bilevel decision - making theories and methods of a hierarchy system, this paper presents bilevel decision models to collect charges due to emission of PAHs for different decision - makers of upper -level government and lower -level enterprises. This model has in some degree solved the inconsistent information happened in previous studies between government and enterprises, and can be used to better con- trol the PAH emissions from enterprises and improve the air quality.
