7-3  能源生产弹性系数
Elasticity Ratio of Energy Production
指     标	Item	2009	2010	2011
能源生产增长速度(%)	Growth Rate of Energy Production over Preceding Year (%)	20.8	16.7	14.9
电力生产增长速度(%)	Growth Rate of Electricity   Production over Preceding Year (%)	5.7	23.4	11.7
生产总值增长速度(%)	Rate of Gross Domestic Product (GDP) over Preceding Year (%)	13.6	14.6	13.9
能源生产弹性系数	Elasticity Ratio of Energy Production	1.53	1.15	1.07
电力生产弹性系数	Elasticity Ratio of Electricity Production	0.42	1.62	0.84
注：生产总值增长速度按不变价计算，能源生产用等价值折算。
a) The growth rates of GDP are calculated at constant prices. Energy production are converted on the basis of equal value.
