ABSTRACT

With the development of China's economy, the research on the relationship between economic growth and environmental quality has become a hot issue in ecological economics. The analysis of Chinese Environmental Kuznets Curve (EKC) was conducted from the perspective of empirical research and theoretical research, and the problems and deficiencies in existing research were explored in this paper. The following can be found from the review of the academic literatures related to Chinese Environmental Kuznets Curve. Firstly, there are different conclusions in different regions. EKC of most provinces is inverted U-shape, some provinces are inverted N-shape and inverted U-shape + positive U-shape, and the results of eastern, central and western provinces are also different. Secondly, different indicators lead to different conclusions such as inverted U-shape, inverted N-shape, inverted U-shape + positive U-shape. Thirdly, different econometric models lead to different conclusions. In research using quadratic polynomial and logarithmic equation, the EKC appears to be inverted U-shape, while the model combined with cubic equation and multiple equations has both inverted U-shape curve and inverted N-shape curve. Fourthly, the existing research lacks the discussion of the formation mechanism of EKC. This paper points out that Chinese scholars should strengthen the theoretical and methodological research on Environmental Kuznets Curve, and forecasts the further relevant key areas.
