山西省环境库兹涅茨曲线的实证分析

Empirical Analysis of Environmental Kuznets Curve in Shanxi Province

选取山西省2007—2021年的人均GDP与工业“三废”排放量数据,建立计量模型,验证环境库兹涅茨曲线对山西省的适用情况。结果表明,山西省“三废”排放量的环境库兹涅茨曲线不符合“U”型或倒“U”型,废水排放量、废气排放量与人均GDP的拟合曲线均为指数模型,一般工业固体废物产生量与人均GDP的拟合曲线为对数模型。

The per capita GDP and industrial waste emissions data of Shanxi Province from 2007 to 2021 are selected to establish an econometric model to verify the application of the environmental Kuznets curve to Shanxi Province.The results show that the environmental Kuznets curve of the three waste emissions in Shanxi Province does not conform to the'U'type or inverted'U'type.The fitting curves of waste water discharged,waste gas emission and per capita GDP are exponential models,and the ftting curves of common industrial solid wastes generated and per capita GDP are logarithmic models.
