指    标	Item	2009	2010	2011
能源消费增长速度(%)	Growth Rate of Energy Consumption over Preceding Year (%)	8.44	10.43	9.86
电力消费增长速度(%)	Growth Rate of Electricity Consumption over Preceding Year (%)	4.53	16.09	14.34
生产总值增长速度(%)	Growth Rate of Gross Domestic Product (GDP) over Preceding Year (%)	13.60	14.46	13.90
能源消费弹性系数	Elasticity Ratio of Energy Consumption	0.62	0.72	0.71
电力消费弹性系数	Elasticity Ratio of Electricity Consumption	0.33	1.11	1.03
注：生产总值增长速度按不变价计算，能源消费用等价值折算。
a) The growth rates of GDP are calculated at constant prices. Energy consumption are converted on the basis of equal value.
