地方政府的雾霾治理政策作用机制——政策工具、空间关联和门槛效应

雾霾治理作为"污染防治攻坚战"的重要内容,地方政府作为环境治理的核心主体,有效提升地方政府环境政策的治霾效果具有重要意义.从政府环境治理的政策工具差异、空间关联和门槛效应的3个视角出发,本文提出了地方政府环境治理降低雾霾污染的3个理论假说,并基于中国2003-2016年30个省(市、区)和2007-2016年217个城...

Environmental policy mechanism of local governments in the treatment of haze pollution:Policy tools,spatial correlations and threshold effects

Smog pollution reduction is an important part of the "tough battle for pollution prevention and control". As the key actor of environmental governance, local governments should play a key role in improving the effectiveness of their environmental policies for smog control.Based on the data of 30 provinces(municipalities, autonomous regions) in China’s mainland from2003 to 2016 and the data of 217 cities from 2007 to 2016, this study used dynamic spatial panels and dynamic panel threshold measurement methods to test relevant theoretical hypotheses. The results show that:(1) Different types of measures of the local governments for environmental governance have various degrees of success on smog pollution control. Specifically, environmental protection legislation and environmental protection investment of local governments have more significant effects in reducing smog pollution, while local governments’ environmental law enforcement has little effect on the suppression of smog pollution.(2) In terms of spatial correlation, the impact of different measures of local government environmental governance in neighboring areas on local smog pollution is also different. Environmental legislation of neighboring regions has increased local smog pollution through the escalation of coordination costs. Although government environmental law enforcement can reduce smog pollution, the effect is not significant;while environmental protection investment in neighboring areas can significantly reduce local smog pollution through the spatial spillover of smog pollution control.(3) The impact of local government environmental governance on smog pollution has a significant threshold effect. When the level of regional technological development or urbanization is high, local government environmental governance can effectively reduce smog pollution, and vice versa. This study divided government environmental governance into three measures: environmental legislation, law enforcement, and investment. This article detailed the mechanism of government environmental governance actions on smog pollution control, and provided a scientific basis for the government to further improve the environmental governance system and win the war of blue sky defense.
