Abstract: The relationship between the economic growth and environmental quality is a hot issue in the environmental economics, and the Environmental Kuznets Curve is a widespread approach. The Traditional Environmental Kuznets Curve model presupposes the existence of curve, then uses a fixed model to fit it, but the inadequacies of this approach is that we are not able to identify every country or regional has such relationship. Therefore, at the background of today's "low carbon economy", we introduce the non-parametric model and makes use of carbon dioxide as the environment index to study this issue. The study results show that: China's economic growth and environment do not exist inverted "U" type curve, FDI and urbanization have a significant statistic effect and non-significant economic effect on China’s environmental quality, trade, energy intensity and urbanization would be harm to the environment.
