Relations Between Total Factor Energy Efficiency and Environmental Pollution
Energy and environmental issues have become the focus of the world.By literature review,we found that most of previous studies just analyzed one of the environmental issues separately,but a few studies were on the relations between energy and environment(especially energy efficiency and environmental pollution).There is a close link between the energy efficiency and environmental pollution,so a in-depth and comprehensive study of the relations is necessary.Firstly,we use the methods of DEA and the cost of pollution clearance to calculate Chinese total factor energy efficiency and economic loss caused by environment pollution in 1989-2007.On the basis of the evaluation of relations between the two,by using the cointegration test and Granger causality test,we draw the conclusions of this article: A long-term equilibrium relationship exists between Chinese total factor energy efficiency and economic loss caused by environmental pollution,and the former is the latter's Granger cause.And we find that the short-term energy efficiency fluctuation has an obvious impact to reducing economic loss caused by environmental pollution and the impact is bigger than long-term energy efficiency fluctuation caused by environmental pollution economic loss.This means that the improvement of total factor energy efficiency plays an important role in reducing environmental pollution,which is also important to the goals of energy-saving and emission reduction.
