摘要
Shanxi Province is a typical resource-based region. After years of economic transformation, the air quality has been at a low level for a long time. The rationalization of industrial structure can measure the effect of economic transformation and whether it has an important impact on air quality. Therefore, it is necessary to study the non-linear impact that the rationalization of industrial structure has had on air quality at different stages, which is of positive significance for the continuing transformation and upgrading of resource-based regions. This study constructs a threshold regression model based on the panel data of 11 provincial cities in Shanxi Province from 2004 to 2016. The results show that the rationalization of industrial structure had a double threshold effect on air quality under different threshold variables. On the whole, optimizing the rationalization of industrial structure in Shanxi Province can improve air quality, and the improvement effect dropped first, and then began to rise. As a result, the current energy transformation and upgrading process should focus on the rationalization of industrial structure to solve the conflict between air quality and economic development.
山西省属于典型的资源型省份,历经多年的经济转型发展,空气质量仍长期处于全国较低水平。产业结构合理化能够对经济转型的效果进行测度,且对空气质量产生重要影响,因此有必要研究不同阶段产业结构合理化对空气质量的非线性影响,这对资源型区域转型升级具有积极意义。本文利用2004–2016年山西省11个省辖市的面板数据构建门限回归模型展开研究。结果显示,不同的门限变量下,产业结构合理化对空气质量均具有双重门限效应,整体上看山西省产业结构合理化程度的提升能够促进空气质量的改善,改善的效果呈现先降后升的趋势。因此目前的能源转型升级过程中应着重提升产业结构合理化程度以解决空气质量与经济发展之间的矛盾。
