The Environmental Kuznets Curve Effects of Energy Intensity and Emission Intensity on Optimizing Chinese Emission-reduction under the Constraint of Energy-saving Policy

摘要

Using Environmental Kuznets Curve theory, this article examines the EKC effect of economic growth, energy intensity and carbon emission intensity on total quantity of carbon emission under the constraint of energy-saving policy. Optimizing energy-consuming structure and decreasing energy-consuming intensity can incline carbon emissions intensity and slow down the increasing speed of carbon emissions quantity. GDP per population and carbon emission intensity have significantly inverted U-shape EKC effect on carbon emission quantity at the confidence of 95% level from 2006 to 2015, accordingly optimizing energy-consuming structure and reducing energy intensity are helpful to incline carbon emission intensity and total quantity growth of carbon emission in eleventh-five and twelfth-five periods under the constraint of energy-saving and emission-reduction policy. However planning target of carbon emission intensity faces greater challenges and risks in the future, Chinese government should introduce a serial of energy-saving and emission-reduction advices and policies in the future.
