This study aims to examine the validity of inverted U-shaped Environmental Kuznets Curve by investigating the relationship between economic growth and environmental pollution for the period from 1966 to 2013 in the USA. Previous studies based on the assumption of parameter stability and obtained parameters do not change over the full sample. This study uses bootstrap rolling window estimation method to detect the possible changes in causal relations and also obtain the parameters for sub-sample periods. The results show that the parameter of economic growth has increasing trend in 1982-1996 sub-sample periods, and it has decreasing trend in 1996-2013 sub-sample periods. Therefore, the existence of inverted U-shaped Environmental Kuznets Curve is confirmed in the USA.
本研究旨在检验倒 U 型环境库兹涅茨曲线的有效性，为此考察了 1966 年至 2013 年间美国经济增长与环境污染之间的关系。基于参数稳定性假设的先前研究获得了整个样本期间参数不变的结果。本研究采用自举滚动窗口估计方法来检测因果关系的可能变化，并为子样本期间获得参数。结果表明，在 1982-1996 年子样本期间，经济增长参数呈上升趋势，而在 1996-2013 年子样本期间，经济增长参数呈下降趋势。因此，在美国证实了倒 U 型环境库兹涅茨曲线的存在。
