A Grey relevancy analysis on the relationship between energy consumption and economic growth in Henan Province

摘要

Energy development and utilization play an important role in Henan's economic growth. During more than past 20 year, energy use efficiency has been improved greatly, but there is still a large potential for energy and emission reduction. Firstly, using the method of Grey relevancy analysis to get the model between energy consumption and economic growth in Henan before and after 1990.Secondly, we analysis the correlation of energy consumption and economic growth from the sides of total energy consumption, energy consumption structure and elasticity of energy consumption. Finally, we got the conclusion that four factors are associated with the dominant energy in Henan Province. The correlation of total energy consumption and coal consumption are greater than unit GDP correlation and the elasticity of energy consumption correlation. It is difficult to change the status that Henan Province's completely depend on coal resources in the short term.
