The Dynamic Relationship between Economic Growth and Energy Consumption——Based on Non-parametric Pointwise Regression Estimation

This paper analyzes the dynamic relationship between economic growth and energy consumption using Chinese interprovincial panel data from 1990 to 2010 by non-parametric pointwise regression estimation.The result shows that: there is a N-shaped curve between per capita GDP and energy consumption,and in the process of the per capita GDP from low to high,there is a steady decreased interval where the per capita income significantly facilitates the increase of energy consumption before and after it,thus the EKC of energy consumption doesn't exist in china.Further study in China's eastern,central and western region shows that high-income areas have an inverted U-shaped relationship between economic growth and energy consumption,and the energy consumption of low-income areas will continue to increase.At last,it gives some suggestions based on these conclusions.
