The spatial spillover of air pollution in Beijing - Tianjin - Hebei region makes the territorial governance model inefficient. At the same time, it is facing the contradiction between environmental governance and economic development. So far, there is still no regional long-term mechanism for coordinated governance of air pollution. Ecological compensation theory is becoming an effective guiding theory to coordinate economic and environmental benefits. There is relatively little research on ecological compensation mechanism in the coordinated control of regional air pollution. Ecological compensation mechanism is an effective tool to promote air pollution control. At the same time, regional cooperation can realize the efficient control of air pollution. Scientifically constructing the cross regional cooperative control model of Beijing, Tianjin and Hebei is a favorable way to implement comprehensive Control of air pollution. This paper discusses the necessity of ecological compensation mechanism for regional coordinated control of air pollution. Referring to practical experience of provinces and cities that have implemented the ecological compensation mechanism for air pollution control, and the effective way to distribute the compensation amount, compensation subject and compensation standard determination method that can be implemented in Beijing - Tianjin - Hebei region are analyzed, further proposing an effective way to establish an ecological compensation mechanism for regional air pollution collaborative control according to its reality.
