产业集聚与雾霾污染的门槛效应研究——以73个PM2.5重点监测城市为例

Study on the threshold effect of industrial agglomeration and haze pollution——taking 73 PM2.5 key monitoring cities as an example

摘要:

经济高速发展带来的环境污染问题,制约了经济的可持续发展,从产业集聚外部性出发结合产业发展周期理论,借助2008-2015年73个PM2.5重点监测城市的面板数据,实证检验产业集聚对雾霾污染的门槛效应,研究发现：(1)产业集聚对雾霾污染具有显著双重门槛效应,当产业集聚水平位于第一、第三区间时,产业集聚具有显著正外部性；当产业集聚水平位于第二门槛区间时,产业集聚对雾霾污染表现为正向影响,但并不显著。(2)环境规制力度与雾霾污染显著负相关。进而提出注重产业集聚动态演进变化,动态调整产业集聚水平；制定严苛环境规制政策,引导产业绿色转型的政策建议。

Abstract:

The problem of environmental pollution brought about by rapid economic development, which restricts the sustainable development of economy, agglomeration externalities of combination of industry from the industrial development cycle theory, with panel data of 73 years 2008-2015 PM2.5 focus on monitoring the city, an empirical test of industrial agglomeration threshold effects, on the haze pollution research found that: (1) the industrial agglomeration has significant dual threshold effect of haze pollution, when the industrial agglomeration level in the first and third interval, industrial agglomeration has significant positive externalities; when the level of industrial agglomeration in the second threshold interval, industrial agglomeration on haze pollution showed positive effects, but not significantly. (2) The intensity of environmental regulation was negatively correlated with the fog and haze pollution. Then we put forward policy recommendations that focus on the dynamic evolution of industrial agglomeration, dynamically adjust the level of industrial agglomeration, formulate harsh environmental regulation policies, and guide industrial green transformation.
