The complexity of the governance of haze can be seen from the formation of haze，because it is far more complex than general pollution emissions，and the difficulty of governance is beyond imagination. When we collect the policy measures which have been passed，it is easy to find that these measures are too single and mechanical，which lack organic connections between each other，with more component force and less resultant force.China’s haze pollution may be more complicated than the fog event in London and photochemical smog events in Los Angeles. As there is still lack of scientific explanation of the cause of haze，perfecting the policy mechanism of preventing and governing haze from the policies and measures’ decision，combination，operation and effect will expand ways of thinking，facilitate governance and multiply efficiency. The governance of China’s urban haze requires scientific environmental and economic considerations，and the path must be balanced with the target. We should not only abandon the negative act，but also prevent extreme actions. A successfully designed governance strategy should strike a balance between governance cost and environmental and economic benefits. Government must play a key role in the governance of the urban haze.
