摘要:

环境质量的改善不仅是环境政策单独作用的结果,通常还与政策作用下产业结构的调整密切相关。本文基于中国2006—2016年197个地级及以上城市的PM2.5年均浓度面板数据,以“大气十条”政策作为环境规制的代理虚拟变量,结合双重差分法,研究“大气十条”政策的实施是否有利于降低京津冀晋鲁蒙、长三角、珠三角3个目标区域内城市的雾霾污染水平,并通过构建产业结构升级指标,探索该政策如何通过产业结构升级影响雾霾污染治理。进一步,采用面板门槛回归模型,验证“大气十条”政策实施背景下产业结构合理化与产业结构高度化对雾霾污染治理是否存在门槛效应。回归结果显示:①双重差分回归中,全样本下,“大气十条”的政策效果不显著;分区域样本下,政策对京津冀晋鲁蒙区域产生了显著的雾霾治理效应,而对长三角和珠三角区域没有产生明显的政策效果。②中介效应模型中,京津冀晋鲁蒙区域“大气十条”政策主要通过产业结构高度化的“量”作用于雾霾污染治理,且为部分中介效应;长三角区域产业结构高度化的“量”作用于雾霾污染治理则为完全中介效应;珠三角区域产业结构升级不具有显著的中介效应。③面板门槛回归中,京津冀晋鲁蒙与周边区域样本、长三角与周边区域样本下产业结构合理化与高度化均存在门槛效应。

Abstract:

The improvement of environmental quality is not only the result of environmental policy, but closely related to the adjustment of industrial structure under the effect of policy. Based on the panel data of the average annual concentration of PM2.5 in 197 prefectural-level and above cities in China from 2006 to 2016, this study took the Air Pollution Prevention and Control Action Plan as the proxy dummy variable of environmental regulation, and combined the difference in differences method to examine whether the implementation of the action plan is conducive to reducing the level of haze pollution in three target areas. By putting the industrial structure upgrading indicators (including industrial structure optimization, the “quantity” of industrial structure supererogation, and the “quality” of industrial structure supererogation) into the model, this study explored how the policy affected the haze pollution control through the upgrading of industrial structure. In addition, a panel threshold regression model was used to examine whether there is a threshold effect of industrial structure optimization and industrial structure supererogation on haze pollution control under the background of the implementation of the action plan. The regression results show that: (1) Using the full sample, the policy effect is not significant. In the subregional samples, the policy has a significant haze control effect in Beijing, Tianjin, Hebei and the surrounding areas, but has no significant policy effect on the Yangtze River Delta and the Pearl River Delta; (2) In the mediation effect model, in Beijing, Tianjin, Hebei and the surrounding areas the policy mainly acts on haze pollution control through the “quantity” of industrial structure supererogation, and the effect is partial intermediary. The “quantity” of industrial structure supererogation in the Yangtze River Delta is complete intermediary when it acts on haze pollution control and the industrial structure upgrading variables in the Pearl River Delta region do not have a significant mediating effect; (3) In the panel threshold regression, threshold effects of industrial structure optimization and industrial structure supererogation are observed in the samples of Beijing-Tianjin-Hebei-Shanxi-Shandong-Inner Mongolia and surrounding areas, and the samples of the Yangtze River Delta and surrounding areas.
