Abstract: Taking Beijing-Tianjin-Hebei region as an example， such cooperative types as industrial transfer， environmental claims of central cities and temporary cooperation in big events could improve the air quality in some indicators or in a certain period of time. However， they fail to sustain due to such management dilemmas as scarcity of interest links and lack of stimulation and supervision， which might intensify regional inequality. The features of new air pollution compounds call for the theoretical claim and practical necessity of constructing a sustainable cooperative governance mechanism. It is suggested that the system improvement and mechanism innovation of Beijing-Tianjin-Hebei regions sustainable collaborative governance on air pollution should be made through organizational cooperation， interest coordination， effective stimulation， policy implementation and various participation.

Key words: air pollution, sustainable collaborative governance, mechanism innovation, Beijing-Tianjin-Hebei region
