运用阈值面板模型方法，在环境库兹涅茨曲线框架下，对我国经济增长与环境质量的关系进行再检验。研究表明，我国的经济增长与环境变量之间存在显著的阈值效应。在经济发展的不同阶段和时期，经济增长对环境负面影响的大小和作用机制不同。在收入较低的阶段，人均收入水平与环境质量之间是单调的线性关系；在收入较高的阶段，二者之间存在倒U型关系，但转折点会随着样本点平均收入水平的提高而上升。随着收入水平的提升而渐次进入更高发展阶段的省份越来越多，使得污染物随之而降低，区域之间发展水平的差异对我国环境问题有重要影响；同时，工业化程度的提升会显著地带来污染排放增加，而技术效率和对外开放水平的提高则有助于促进环境改善。

This paper uses threshold panel data model to verify the relationship between economic growth and environment quality under the framework of Environmental Kuznets Curve. The study shows that there is an significant threshold effect between China＇s economic growth rate and the envi- ronment variable. And in different phases and stages of economic development, economic growth~s negative impacts on environment differ, and the affecting mechanism varies. When in the lower in- come stage, per capita income level relates to environment quality in a linear way. However when in- come increased, an inverted U type correlation comes up, with its turning point at the increasing level of sample average income. The number of provinces gradually developing into a higher level is increas- ing as income level goes up, resulting in much less pollutants generated while income surges. There- fore differences among regions in terms of their development levels have significant importance to Chi- na＇s environment. In the meantime, industrialization brings in an increasingly serious pollution, while technical efficiency and opening up to the outside are beneficial to environmental improvement.
